The Newtowne C4-27 is the lowest priced chamber Newtowne makes and the one most first-time buyers start with. At full pressure it is 27 inches across and 84 inches long, on a 29.75 x 67.5 inch steel frame. One average-sized adult lies flat inside. It runs at 4 PSI, about 1.3 ATA, is FDA cleared under 510(k) K051759, and is built by Newtowne Hyperbarics in Pocomoke City, Maryland. Shipping is included. A prescription is required to buy it.
RecovAthlete is an authorized dealer for Newtowne Hyperbarics. Every order ships from the Newtowne factory with the Newtowne warranty and direct factory support.

Most people shopping for a hyperbaric chamber for sale ask one thing: what does a US-built, FDA cleared chamber cost at the entry point? The C4-27 is that answer. Same 4 PSI, same triple zipper, same relief valves, same Maryland factory as the larger Newtowne cylinders. What you give up is width. At 27 inches it fits an average adult lying flat with arms at the sides.
27 inches is the narrowest Newtowne cylinder. Newtowne rates it for an average-sized adult. If you have a broad frame, dislike enclosed spaces, or want to sit up, look at the Newtowne C4-34 before you order. All Newtowne chambers are final sale, so the size check matters.
Federal law restricts this device to sale on the order of a physician, dentist, or other qualified professional. You may place your order before submitting a prescription, but RecovAthlete cannot release the chamber for shipment until the documentation has been verified. Details are in the prescription section below.
Newtowne sells through authorized dealers. What changes when you buy here is what comes with the order.
Newtowne's product page gives the C4-27 as 27 inches in diameter and 84 inches long at full pressure. Sessions run about an hour, and 27 inches means your arms stay at your sides the whole time. If that sounds tight, it probably is; the C4-34 adds 7 inches of diameter. The Class 4 manual lists the chamber at 92 inches, which is the flat length before the ends round off under pressure. Plan your floor space on the 67.5 inch frame plus the rounded ends. The bladder weighs about 19 lb.
Operating pressure is 4 PSI, or 1.3 ATA, the same as every Newtowne Class 4 chamber. The 80 L compressor inflates slower than the 120 L on the C4-34, but reaches the same 4 PSI. It has its own relief valve, and the chamber has two more preset at the factory to 4 to 4.4 PSI. One viewport, two accessory ports, top or side zipper placement, and a power outage alarm are standard. The internal gauge and the 4 inch mattress are upgrades; a half inch chamber mat is included.
Position the chamber and frame at least 3 ft from heat or open flame, in a cool room. Place the compressor 4 to 6 ft from the chamber with slack in the air hose. Pressure raises the inside temperature 5 to 10 F during a session. The frame stands on end with the folded chamber inside it between sessions.
Power is a standard grounded 120 V outlet. The compressor has no switch; you plug it in to start. First inflation takes 10 to 20 minutes. Newtowne supplies a manual, video training, and setup help by video call. Replace the compressor filter once a year and lubricate the horseshoe-shaped end stops on the airtight zipper every 10 to 20 uses with the tube Newtowne supplies.
| What you get | The feature behind it |
|---|---|
| The lowest priced way into a Newtowne. | Same 4 PSI, zipper system, relief valves, and factory as the C4-34 and C4-40. Narrower bladder, 80 L compressor. |
| Fits where the bigger cylinders will not. | 67.5 in frame. Frame stands on end with the chamber folded inside for storage. |
| Enter from the top or the side. | Two hanger positions on the frame. Pick whichever suits your mobility. |
| Controls reachable from inside and outside. | Triple zipper and air deflate valve work from both sides. A power outage alarm sounds if the pump stops. |
| Redundant pressure control. | Two pressure relief valves on the chamber plus a relief valve on the compressor. Only one is needed; the others are backups. |
| You control how fast your ears adjust. | The internal air deflate valve lets you pause or slow pressurization from inside. |
| Light and a view out. | One viewport with a hard port cover that stops bulging under pressure. |
| Ready for an oxygen concentrator. | Oxygen kit in the box: valve, hose, adult mask, adult cannula. Two accessory ports; the oxygen valve uses one when installed. |

Confirm three things. You are comfortable lying flat in 27 inches; if in doubt, call us. You have floor space for the 67.5 in frame plus the rounded ends and a grounded 120 V outlet near where the compressor will sit. You have a prescription, or a plan to get one.
The oxygen concentrator is a separate purchase and needs its own prescription. The internal gauge and 4 in mattress are upgrades. A concentrator and extended warranty can be added from the options at the top of this page.

Diameter is the decision. Sessions run about an hour, so the wider the chamber, the more room you have to stay comfortable. The C4-27 is 27 inches across; the C4-34 is 34 inches across with the gauge, mattress, and a faster 120 L compressor included. The Newtowne C4-Shoe is a seated alternative if lying flat is not for you.

Yes. Newtowne chambers are FDA cleared and registered under 510(k) number K051759. Newtowne's stated indication for use is acute mountain sickness. Any other use is off label, and your session schedule is set by your prescriber, not by Newtowne or RecovAthlete.
Newtowne rates the C4-27 for an average-sized adult lying flat. It does not publish a height or weight limit. You lie with your arms at your sides. If you have a broad frame or dislike enclosed spaces, the C4-34 adds 7 inches of width and a second viewport. Call 866-861-6317 and we will talk it through before you order, because Newtowne chambers are final sale.
Newtowne's product page gives 84 inches at full pressure. The Class 4 manual gives 92 inches, which is the flat length before the ends round off. Both are Newtowne figures for the same chamber. Plan your space on the 67.5 inch frame plus the rounded ends.

Newtowne publishes a guide for pet and veterinary use of its chambers. For a 27 inch chamber it suggests a crate with a girth (2W + 2H) of no more than 64 inches and a length of no more than 30 inches. Newtowne states a veterinary prescription is not required for pet use. Talk to your vet first. The pet guide is linked below.
No. The oxygen kit is included: valve, hose, adult mask, and adult cannula. The concentrator is sold separately and needs its own prescription. Newtowne recommends a 10 L unit run at 7 to 9 LPM. You can add one from the options at the top of this page.
Newtowne covers defects in material and workmanship for 2 years. Years 3, 4, and 5 can be added inside the first 2 years; the prices are in the spec table. The owner pays shipping to and from the factory. Zipper damage from misuse and any use of sealants, adhesives, or solvents are not covered. Full terms are in the warranty tab on this page.

You may place your order before submitting a prescription, but RecovAthlete cannot release the chamber for shipment until the documentation has been verified. Details are in the prescription section below.
Newtowne sells through authorized dealers. What changes when you buy here is what comes with the order.
Newtowne's product page gives the C4-27 as 27 inches in diameter and 84 inches long at full pressure. Sessions run about an hour, and 27 inches means your arms stay at your sides the whole time. If that sounds tight, it probably is; the C4-34 adds 7 inches of diameter. The Class 4 manual lists the chamber at 92 inches, which is the flat length before the ends round off under pressure. Plan your floor space on the 67.5 inch frame plus the rounded ends. The bladder weighs about 19 lb.
Operating pressure is 4 PSI, or 1.3 ATA, the same as every Newtowne Class 4 chamber. The 80 L compressor inflates slower than the 120 L on the C4-34, but reaches the same 4 PSI. It has its own relief valve, and the chamber has two more preset at the factory to 4 to 4.4 PSI. One viewport, two accessory ports, top or side zipper placement, and a power outage alarm are standard. The internal gauge and the 4 inch mattress are upgrades; a half inch chamber mat is included.
Position the chamber and frame at least 3 ft from heat or open flame, in a cool room. Place the compressor 4 to 6 ft from the chamber with slack in the air hose. Pressure raises the inside temperature 5 to 10 F during a session. The frame stands on end with the folded chamber inside it between sessions.
Power is a standard grounded 120 V outlet. The compressor has no switch; you plug it in to start. First inflation takes 10 to 20 minutes. Newtowne supplies a manual, video training, and setup help by video call. Replace the compressor filter once a year and lubricate the horseshoe-shaped end stops on the airtight zipper every 10 to 20 uses with the tube Newtowne supplies.
| What you get | The feature behind it |
|---|---|
| The lowest priced way into a Newtowne. | Same 4 PSI, zipper system, relief valves, and factory as the C4-34 and C4-40. Narrower bladder, 80 L compressor. |
| Fits where the bigger cylinders will not. | 67.5 in frame. Frame stands on end with the chamber folded inside for storage. |
| Enter from the top or the side. | Two hanger positions on the frame. Pick whichever suits your mobility. |
| Controls reachable from inside and outside. | Triple zipper and air deflate valve work from both sides. A power outage alarm sounds if the pump stops. |
| Redundant pressure control. | Two pressure relief valves on the chamber plus a relief valve on the compressor. Only one is needed; the others are backups. |
| You control how fast your ears adjust. | The internal air deflate valve lets you pause or slow pressurization from inside. |
| Light and a view out. | One viewport with a hard port cover that stops bulging under pressure. |
| Ready for an oxygen concentrator. | Oxygen kit in the box: valve, hose, adult mask, adult cannula. Two accessory ports; the oxygen valve uses one when installed. |

Confirm three things. You are comfortable lying flat in 27 inches; if in doubt, call us. You have floor space for the 67.5 in frame plus the rounded ends and a grounded 120 V outlet near where the compressor will sit. You have a prescription, or a plan to get one.
The oxygen concentrator is a separate purchase and needs its own prescription. The internal gauge and 4 in mattress are upgrades. A concentrator and extended warranty can be added from the options at the top of this page.

Diameter is the decision. Sessions run about an hour, so the wider the chamber, the more room you have to stay comfortable. The C4-27 is 27 inches across; the C4-34 is 34 inches across with the gauge, mattress, and a faster 120 L compressor included. The Newtowne C4-Shoe is a seated alternative if lying flat is not for you.

Federal law restricts sale of this device to the order of a physician, dentist, or other qualified professional. Practitioner and clinic purchases are subject to the same license and prescription verification. You may place your order first, but RecovAthlete cannot release the chamber for shipment until the documentation has been verified.
Need a prescriber? Dr. Garry Warner offers HBOT consults by telehealth at (303) 915-4813, drgarrywarner.com. His fee is paid to him directly; RecovAthlete is not part of that transaction. Email your prescription to info@recovathlete.com. If you are buying a concentrator, RecovAthlete asks for both items on one prescription.
The current price is at the top of this page and shipping is included. It is the lowest priced chamber Newtowne makes. The oxygen concentrator, internal gauge, and 4 in mattress are separate; their prices are in the upgrade table above. Financing is available for qualified buyers, and military, veteran, and first responder pricing is available by phone.
Yes. Newtowne chambers are FDA cleared and registered under 510(k) number K051759. Newtowne's stated indication for use is acute mountain sickness. Any other use is off label, and your session schedule is set by your prescriber, not by Newtowne or RecovAthlete.
Newtowne rates the C4-27 for an average-sized adult lying flat. It does not publish a height or weight limit. You lie with your arms at your sides. If you have a broad frame or dislike enclosed spaces, the C4-34 adds 7 inches of width and a second viewport. Call 866-861-6317 and we will talk it through before you order, because Newtowne chambers are final sale.
Newtowne's product page gives 84 inches at full pressure. The Class 4 manual gives 92 inches, which is the flat length before the ends round off. Both are Newtowne figures for the same chamber. Plan your space on the 67.5 inch frame plus the rounded ends.
We ship Newtowne chambers within the US. For Canadian buyers, we ship to the UPS Store nearest you on the US side of the border. You collect it there and carry it across yourself. Call 866-861-6317 to set this up. We do not ship to PO boxes.
Newtowne publishes a guide for pet and veterinary use of its chambers. For a 27 inch chamber it suggests a crate with a girth (2W + 2H) of no more than 64 inches and a length of no more than 30 inches. Newtowne states a veterinary prescription is not required for pet use. Talk to your vet first. The pet guide is linked below.
No. The oxygen kit is included: valve, hose, adult mask, and adult cannula. The concentrator is sold separately and needs its own prescription. Newtowne recommends a 10 L unit run at 7 to 9 LPM. You can add one from the options at the top of this page.
Newtowne covers defects in material and workmanship for 2 years. Years 3, 4, and 5 can be added inside the first 2 years; the prices are in the spec table. The owner pays shipping to and from the factory. Zipper damage from misuse and any use of sealants, adhesives, or solvents are not covered. Full terms are in the warranty tab on this page.
Not sure 27 inches is right for you? Call 866-861-6317, 9am to 6pm EST, Monday to Friday. We will check the fit, the floor space, and the prescription steps with you before you order.

Buying for yourself, spread the cost through Affirm at checkout. Buying for a gym, clinic, spa, or studio, apply with one of four business lenders and put the whole room on a single application.
RecovAthlete has no control over any financing decision. Approval is based on your creditworthiness and is solely the lender's decision.
Affirm at checkout. Rates run 0% to 36% APR based on your credit profile. Soft check to prequalify, so no impact on your score. No prepayment penalty.
Brickhouse Capital, Reliant Capital, Acorn Finance, or KWIPPED. Apply with two of the four and compare. Financed equipment can qualify for a Section 179 deduction. Confirm with your accountant.
Every page below has real prices, real monthly payment examples, and the lender comparison for that category. Pick the one you are buying.
Most business buyers are not buying one machine. They are building a room. Sauna, cold plunge, red light, vibration, hyperbaric, cryotherapy, and halotherapy all finance on the same paper through the same four lenders, and RecovAthlete quotes every category on one purchase order.
That means one freight schedule, one install window, and one financing application instead of six. It also gets you a better rate, because a bigger number on one application beats six small ones with six hard inquiries.
See commercial recovery equipment financing, or call 866-861-6317 and we will price the room.
| Lender | Type | Amount | Speed | Best for |
|---|---|---|---|---|
| Affirm | Consumer, at checkout | Order total | Seconds | Personal purchases. 0% to 36% APR based on credit. Soft check to prequalify. |
| Brickhouse Capital | Direct equipment lender | Up to $250K on a one-page application, $1M+ with financials | ~24 hours | A full room or a full floor. Credit decisions made in-house. Tied to the business, not your personal credit report. |
| Reliant Capital | Lender and broker | Up to $500K application-only, $5M with financials | 2 to 4 hours | Medical, aesthetic, and wellness. Deferred payment options. New or used equipment. |
| Acorn Finance | Lending marketplace | $1,000 to $100,000 | 60 seconds to prequalify | Comparing offers. One application goes to 30 or more lenders with no impact to your score. |
| KWIPPED (APPROVE) | Lender marketplace | Minimum $1,500 equipment value | 60-second application | Larger commercial orders. Lenders compete, which usually returns the best APR. Businesses only. |
Apply with two of the four and compare. It costs nothing and the spread between offers is often significant.

Pay in 4 splits the purchase into four interest-free payments charged every two weeks. Monthly installments spread the cost over a longer term, with rates from 0% to 36% APR depending on your credit profile. You see the exact terms before you agree to anything. No origination fees, no prepayment penalty, no late fees.
Prequalification does not. Affirm and Acorn Finance both run a soft check to show you offers, which has no impact on your score. Proceeding with a monthly installment plan or a business loan may involve a hard inquiry. That is why it pays to prequalify with more than one lender first and only proceed with the best offer.
Yes, and for most business buyers it is the better route. Brickhouse funds up to $250,000 on a one-page application with no financial statements. Reliant approves in 2 to 4 hours. Business financing is usually tied to the business rather than your personal credit report, and financed equipment can qualify for a Section 179 deduction. Confirm the tax position with your accountant.
No. This is the most common and most expensive mistake. Separate applications mean separate hard inquiries, separate payments, and a worse rate on each, because every individual ticket is small. Get one quote from RecovAthlete covering everything you are buying, including freight, and put that single number on one application.
Financed equipment can qualify. Section 179 lets US businesses deduct the cost of qualifying equipment in the year it is placed in service, and financing the purchase does not by itself disqualify it. The equipment must be in service, not merely ordered, within the tax year. Annual limits and eligibility rules are set by the IRS and change year to year, so consult your accountant.
Freight, yes. On Affirm it is part of the order total at checkout. On business financing, put freight on the RecovAthlete quote and the whole quote amount goes on the application. Installation and room construction are harder, because some equipment lenders will not fund non-equipment costs. Ask the lender before you sign.
Yes. Affirm charges no prepayment penalties. Acorn Finance and most business lenders also allow early payoff without penalty.
Tell us what you are buying and whether it is personal or for a business. We will point you at the right two lenders and quote freight and install as one number, which is also the number that goes on the application.
Call 866-861-6317 Book a 30 minute callThe Newtowne C4-27 is the lowest priced chamber Newtowne makes and the one most first-time buyers start with. At full pressure it is 27 inches across and 84 inches long, on a 29.75 x 67.5 inch steel frame. One average-sized adult lies flat inside. It runs at 4 PSI, about 1.3 ATA, is FDA cleared under 510(k) K051759, and is built by Newtowne Hyperbarics in Pocomoke City, Maryland. Shipping is included. A prescription is required to buy it.
RecovAthlete is an authorized dealer for Newtowne Hyperbarics. Every order ships from the Newtowne factory with the Newtowne warranty and direct factory support.

Most people shopping for a hyperbaric chamber for sale ask one thing: what does a US-built, FDA cleared chamber cost at the entry point? The C4-27 is that answer. Same 4 PSI, same triple zipper, same relief valves, same Maryland factory as the larger Newtowne cylinders. What you give up is width. At 27 inches it fits an average adult lying flat with arms at the sides.
27 inches is the narrowest Newtowne cylinder. Newtowne rates it for an average-sized adult. If you have a broad frame, dislike enclosed spaces, or want to sit up, look at the Newtowne C4-34 before you order. All Newtowne chambers are final sale, so the size check matters.
Federal law restricts this device to sale on the order of a physician, dentist, or other qualified professional. You may place your order before submitting a prescription, but RecovAthlete cannot release the chamber for shipment until the documentation has been verified. Details are in the prescription section below.
Newtowne sells through authorized dealers. What changes when you buy here is what comes with the order.
Newtowne's product page gives the C4-27 as 27 inches in diameter and 84 inches long at full pressure. Sessions run about an hour, and 27 inches means your arms stay at your sides the whole time. If that sounds tight, it probably is; the C4-34 adds 7 inches of diameter. The Class 4 manual lists the chamber at 92 inches, which is the flat length before the ends round off under pressure. Plan your floor space on the 67.5 inch frame plus the rounded ends. The bladder weighs about 19 lb.
Operating pressure is 4 PSI, or 1.3 ATA, the same as every Newtowne Class 4 chamber. The 80 L compressor inflates slower than the 120 L on the C4-34, but reaches the same 4 PSI. It has its own relief valve, and the chamber has two more preset at the factory to 4 to 4.4 PSI. One viewport, two accessory ports, top or side zipper placement, and a power outage alarm are standard. The internal gauge and the 4 inch mattress are upgrades; a half inch chamber mat is included.
Position the chamber and frame at least 3 ft from heat or open flame, in a cool room. Place the compressor 4 to 6 ft from the chamber with slack in the air hose. Pressure raises the inside temperature 5 to 10 F during a session. The frame stands on end with the folded chamber inside it between sessions.
Power is a standard grounded 120 V outlet. The compressor has no switch; you plug it in to start. First inflation takes 10 to 20 minutes. Newtowne supplies a manual, video training, and setup help by video call. Replace the compressor filter once a year and lubricate the horseshoe-shaped end stops on the airtight zipper every 10 to 20 uses with the tube Newtowne supplies.
| What you get | The feature behind it |
|---|---|
| The lowest priced way into a Newtowne. | Same 4 PSI, zipper system, relief valves, and factory as the C4-34 and C4-40. Narrower bladder, 80 L compressor. |
| Fits where the bigger cylinders will not. | 67.5 in frame. Frame stands on end with the chamber folded inside for storage. |
| Enter from the top or the side. | Two hanger positions on the frame. Pick whichever suits your mobility. |
| Controls reachable from inside and outside. | Triple zipper and air deflate valve work from both sides. A power outage alarm sounds if the pump stops. |

| Ready for an oxygen concentrator. | Oxygen kit in the box: valve, hose, adult mask, adult cannula. Two accessory ports; the oxygen valve uses one when installed. |

Confirm three things. You are comfortable lying flat in 27 inches; if in doubt, call us. You have floor space for the 67.5 in frame plus the rounded ends and a grounded 120 V outlet near where the compressor will sit. You have a prescription, or a plan to get one.
The oxygen concentrator is a separate purchase and needs its own prescription. The internal gauge and 4 in mattress are upgrades. A concentrator and extended warranty can be added from the options at the top of this page.

Diameter is the decision. Sessions run about an hour, so the wider the chamber, the more room you have to stay comfortable. The C4-27 is 27 inches across; the C4-34 is 34 inches across with the gauge, mattress, and a faster 120 L compressor included. The Newtowne C4-Shoe is a seated alternative if lying flat is not for you.

Yes. Newtowne chambers are FDA cleared and registered under 510(k) number K051759. Newtowne's stated indication for use is acute mountain sickness. Any other use is off label, and your session schedule is set by your prescriber, not by Newtowne or RecovAthlete.
Newtowne rates the C4-27 for an average-sized adult lying flat. It does not publish a height or weight limit. You lie with your arms at your sides. If you have a broad frame or dislike enclosed spaces, the C4-34 adds 7 inches of width and a second viewport.

The Newtowne C4-27 is the lowest priced chamber Newtowne makes and the one most first-time buyers start with. At full pressure it is 27 inches across and 84 inches long, on a 29.75 x 67.5 inch steel frame. One average-sized adult lies flat inside. It runs at 4 PSI, about 1.3 ATA, is FDA cleared under 510(k) K051759, and is built by Newtowne Hyperbarics in Pocomoke City, Maryland. Shipping is included. A prescription is required to buy it.
RecovAthlete is an authorized dealer for Newtowne Hyperbarics. Every order ships from the Newtowne factory with the Newtowne warranty and direct factory support.

Most people shopping for a hyperbaric chamber for sale ask one thing: what does a US-built, FDA cleared chamber cost at the entry point? The C4-27 is that answer. Same 4 PSI, same triple zipper, same relief valves, same Maryland factory as the larger Newtowne cylinders. What you give up is width. At 27 inches it fits an average adult lying flat with arms at the sides.
27 inches is the narrowest Newtowne cylinder. Newtowne rates it for an average-sized adult. If you have a broad frame, dislike enclosed spaces, or want to sit up, look at the Newtowne C4-34 before you order. All Newtowne chambers are final sale, so the size check matters.
Federal law restricts this device to sale on the order of a physician, dentist, or other qualified professional. You may place your order before submitting a prescription, but RecovAthlete cannot release the chamber for shipment until the documentation has been verified. Details are in the prescription section below.
Newtowne sells through authorized dealers. What changes when you buy here is what comes with the order.
Newtowne's product page gives the C4-27 as 27 inches in diameter and 84 inches long at full pressure. Sessions run about an hour, and 27 inches means your arms stay at your sides the whole time. If that sounds tight, it probably is; the C4-34 adds 7 inches of diameter. The Class 4 manual lists the chamber at 92 inches, which is the flat length before the ends round off under pressure. Plan your floor space on the 67.5 inch frame plus the rounded ends. The bladder weighs about 19 lb.
Operating pressure is 4 PSI, or 1.3 ATA, the same as every Newtowne Class 4 chamber. The 80 L compressor inflates slower than the 120 L on the C4-34, but reaches the same 4 PSI. It has its own relief valve, and the chamber has two more preset at the factory to 4 to 4.4 PSI. One viewport, two accessory ports, top or side zipper placement, and a power outage alarm are standard. The internal gauge and the 4 inch mattress are upgrades; a half inch chamber mat is included.
Position the chamber and frame at least 3 ft from heat or open flame, in a cool room. Place the compressor 4 to 6 ft from the chamber with slack in the air hose. Pressure raises the inside temperature 5 to 10 F during a session. The frame stands on end with the folded chamber inside it between sessions.
Power is a standard grounded 120 V outlet. The compressor has no switch; you plug it in to start. First inflation takes 10 to 20 minutes. Newtowne supplies a manual, video training, and setup help by video call. Replace the compressor filter once a year and lubricate the horseshoe-shaped end stops on the airtight zipper every 10 to 20 uses with the tube Newtowne supplies.
| What you get | The feature behind it |
|---|---|
| The lowest priced way into a Newtowne. | Same 4 PSI, zipper system, relief valves, and factory as the C4-34 and C4-40. Narrower bladder, 80 L compressor. |
| Fits where the bigger cylinders will not. | 67.5 in frame. Frame stands on end with the chamber folded inside for storage. |
| Enter from the top or the side. | Two hanger positions on the frame. Pick whichever suits your mobility. |
| Controls reachable from inside and outside. | Triple zipper and air deflate valve work from both sides. A power outage alarm sounds if the pump stops. |
| Redundant pressure control. | Two pressure relief valves on the chamber plus a relief valve on the compressor. Only one is needed; the others are backups. |
| You control how fast your ears adjust. | The internal air deflate valve lets you pause or slow pressurization from inside. |
| Light and a view out. | One viewport with a hard port cover that stops bulging under pressure. |
| Ready for an oxygen concentrator. | Oxygen kit in the box: valve, hose, adult mask, adult cannula. Two accessory ports; the oxygen valve uses one when installed. |

Confirm three things. You are comfortable lying flat in 27 inches; if in doubt, call us. You have floor space for the 67.5 in frame plus the rounded ends and a grounded 120 V outlet near where the compressor will sit. You have a prescription, or a plan to get one.
The oxygen concentrator is a separate purchase and needs its own prescription. The internal gauge and 4 in mattress are upgrades. A concentrator and extended warranty can be added from the options at the top of this page.

Diameter is the decision. Sessions run about an hour, so the wider the chamber, the more room you have to stay comfortable. The C4-27 is 27 inches across; the C4-34 is 34 inches across with the gauge, mattress, and a faster 120 L compressor included. The Newtowne C4-Shoe is a seated alternative if lying flat is not for you.

Need a prescriber? Dr. Garry Warner offers HBOT consults by telehealth at (303) 915-4813, drgarrywarner.com. His fee is paid to him directly; RecovAthlete is not part of that transaction. Email your prescription to info@recovathlete.com. If you are buying a concentrator, RecovAthlete asks for both items on one prescription.
The current price is at the top of this page and shipping is included. It is the lowest priced chamber Newtowne makes. The oxygen concentrator, internal gauge, and 4 in mattress are separate; their prices are in the upgrade table above. Financing is available for qualified buyers, and military, veteran, and first responder pricing is available by phone.
Yes. Newtowne chambers are FDA cleared and registered under 510(k) number K051759. Newtowne's stated indication for use is acute mountain sickness. Any other use is off label, and your session schedule is set by your prescriber, not by Newtowne or RecovAthlete.
Newtowne rates the C4-27 for an average-sized adult lying flat. It does not publish a height or weight limit. You lie with your arms at your sides. If you have a broad frame or dislike enclosed spaces, the C4-34 adds 7 inches of width and a second viewport. Call 866-861-6317 and we will talk it through before you order, because Newtowne chambers are final sale.
Newtowne's product page gives 84 inches at full pressure. The Class 4 manual gives 92 inches, which is the flat length before the ends round off. Both are Newtowne figures for the same chamber. Plan your space on the 67.5 inch frame plus the rounded ends.
We ship Newtowne chambers within the US. For Canadian buyers, we ship to the UPS Store nearest you on the US side of the border. You collect it there and carry it across yourself. Call 866-861-6317 to set this up. We do not ship to PO boxes.
Newtowne publishes a guide for pet and veterinary use of its chambers. For a 27 inch chamber it suggests a crate with a girth (2W + 2H) of no more than 64 inches and a length of no more than 30 inches. Newtowne states a veterinary prescription is not required for pet use. Talk to your vet first. The pet guide is linked below.
No. The oxygen kit is included: valve, hose, adult mask, and adult cannula. The concentrator is sold separately and needs its own prescription. Newtowne recommends a 10 L unit run at 7 to 9 LPM. You can add one from the options at the top of this page.
Newtowne covers defects in material and workmanship for 2 years. Years 3, 4, and 5 can be added inside the first 2 years; the prices are in the spec table. The owner pays shipping to and from the factory. Zipper damage from misuse and any use of sealants, adhesives, or solvents are not covered. Full terms are in the warranty tab on this page.
Not sure 27 inches is right for you? Call 866-861-6317, 9am to 6pm EST, Monday to Friday. We will check the fit, the floor space, and the prescription steps with you before you order.

Here is exactly how OxyRevo equipment fits within U.S. and international standards, followed by the full list of manufacturer certification and test documents behind every chamber we sell.
OxyRevo chambers are CE certified and UKCA verified, but not FDA cleared for medical use in the United States. They are designed for wellness and recovery applications. If you need an FDA cleared chamber, call us and we will point you to the models that carry that clearance.
The FDA clears soft chambers only up to 1.3 ATA for altitude sickness. Using any chamber for wellness or recovery is off-label use: legal, but not FDA evaluated. Chambers at 1.4 to 2.0 ATA are typically Class II devices requiring a prescription and PVHO-1 compliance in the U.S.
Unless stated for an FDA cleared product, the FDA has not evaluated products or statements on RecovAthlete.com, our products do not diagnose, treat, cure, or prevent any disease, and all content is educational only. Consult a licensed provider before use, especially if you are pregnant, managing a medical condition, or taking prescription medication.
Results vary and are not guaranteed. RecovAthlete and its affiliates are not liable for injury, harm, or adverse effects from the use or misuse of our products, and users assume full responsibility for product use.
OxyRevo chambers are made by Zhuji Belecon Health Technology Co., Ltd. The manufacturer holds 21 certification and test documents covering the chambers, compressors, tanks and inflatable bags. RecovAthlete has been an authorized OxyRevo dealer since 2023 and sells 11 models in the US. Certificates are issued to the manufacturer and cover the full range, including models we do not stock.
CE certification (issued by Ente Certificazione Macchine, Italy) covers European machinery, electrical and pressure equipment safety rules. UKCA verification (ICR Polska) covers the equivalent UK regulations. ISO 13485:2016 is the medical-device quality standard. EMC testing confirms no interference with home electronics, and RoHS and REACH testing confirms the foam, seals and fabric contain no restricted chemicals.
