Lie flat, pull the triple zipper closed, and the 80 L compressor brings the Newtowne C4-27 to 4 PSI in 10 to 20 minutes. This is a mild hyperbaric chamber for home use, sized for one average-sized adult, arms at the sides, with one viewport for light and a view out. It is the lowest priced hyperbaric chamber Newtowne makes, built in Pocomoke City, Maryland, and the one most first-time buyers start with. At about 19 lb the bladder is portable and folds into the frame between sessions.
✓ RecovAthlete is an authorized Newtowne Hyperbarics dealer. Every order ships from the Maryland factory with the Newtowne warranty and direct factory support.
Read this before you order: width, final sale, prescription
27 inches is the narrowest Newtowne cylinder, rated for an average-sized adult lying flat. Broad frame, or want to sit up? See the C4-34 or C4-Shoe first. All sales are final.
A prescription is required. Order first if you like; we cannot ship until it is verified. See the FAQ tab.
Why buy the C4-27 from RecovAthlete
Financing and military pricing
Financing options spread the affordable C4-27 across monthly payments for qualified US buyers, home or clinic. Call 866-861-6317 for current rates.
Military, veteran, and first responder pricing is available with valid ID. Email a copy to support@recovathlete.com after you order; the chamber ships once it is verified.
Before you order
Confirm three things. You are comfortable lying flat in 27 inches. You have floor space for the frame plus the rounded ends, and a grounded 120 V outlet near the compressor. You have a prescription, or a plan to get one.
If you are an average-sized adult who is fine lying flat, want a US-built FDA cleared hyperbaric chamber, and want to spend the least to get one, the C4-27 is the Newtowne model to buy. Call 866-861-6317, 9am to 6pm EST, Monday to Friday, and we will check the fit before you order.

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 away with slack in the air hose. Pressure raises the inside temperature 5 to 10 F during a session. Between sessions the frame stands on end with the folded chamber inside it.
Power is a standard grounded 120 V outlet. The compressor has no switch; you plug it in to start. Replace the compressor filter once a year and lubricate the horseshoe end stops on the airtight zipper every 10 to 20 uses with the tube Newtowne supplies. Newtowne provides a manual, video training, and setup help by video call.
Safety: read before first use
Newtowne's stated indication for the C4-27 is acute mountain sickness. Any other use is off label, and your session schedule is set by your prescriber, not by Newtowne or RecovAthlete.
Need a replacement part or a spare filter? Call 866-861-6317 and we will order it from the factory.
Delivers oxygen through the mask or cannula while the chamber runs on room air. Needs its own prescription; RecovAthlete asks for it on the same prescription as the chamber.
Replaces the included chamber mat with a shaped 4 in foam mattress and cover for a longer session lying flat.
Adds a gauge you read from inside the chamber, alongside the external gauge fitted as standard.
| Option | Price | What it adds |
|---|---|---|
| 4 in curved foam mattress | $275 | Shaped 4 in mattress with cover |
| Internal pressure gauge | $150 | Gauge read from inside the chamber |
| Extended warranty, year 3 | $440 | Material and workmanship cover, year 3 |
| Extended warranty, year 4 | $540 | Material and workmanship cover, year 4 |
| Extended warranty, year 5 | $640 | Material and workmanship cover, year 5 |
Extended years are added inside the first 2 years. Add the concentrator and warranty from the options at the top of this page; add the gauge and mattress as products to your cart.
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 callCompare the three Newtowne mild hyperbaric chambers by diameter. Sessions run about an hour, so the wider the chamber, the more room you have to stay comfortable lying flat. The C4-27 is the entry model for home use; the C4-Shoe is the seated option if lying flat is not for you.
Newtowne's lowest priced chamber. Lie flat, arms at the sides.
More room to accommodate a broader frame, with the gauge and mattress already in the box.
Sit upright inside, or lie down if you are under 5 ft 4 in.

The current price is at the top of this page, and shipping is included with no sales tax. The C4-27 is the lowest priced chamber Newtowne makes. The oxygen concentrator, internal gauge, and 4 in mattress are separate; their prices are in the upgrades tab. Financing is available for qualified buyers, and military, veteran, and first responder pricing is available by phone at 866-861-6317.
The C4-27 price covers the chamber bladder, the steel frame, an 80 L compressor, the oxygen kit, and factory setup support, all built in Maryland. It is the entry point in the Newtowne range; the wider C4-34 and C4-40 cost more because they add diameter, a faster compressor, and more ports. RecovAthlete price includes shipping and no sales tax, so the number you see is close to the number you pay.
Yes, for qualified US buyers. RecovAthlete works with Brickhouse Capital, Reliant Capital, Acorn Finance, and KWIPPED to spread the C4-27 across monthly payments. Both home buyers and clinics qualify. Call 866-861-6317 for current rates and terms, since they change with the lender and your approval.
Newtowne rates the C4-27 for an average-sized adult lying flat, with arms at the sides. It does not publish a height or weight limit. If you have a broad frame or dislike enclosed spaces, the wider C4-34 mild hyperbaric chamber 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.
Plan around the frame, which is 29.75 in wide by 67.5 in long, plus room for the rounded ends of the chamber at full pressure and for the compressor 4 to 6 ft to one side. Keep the chamber at least 3 ft from heat or open flame. Between sessions the frame stands on end with the chamber folded inside, so storage takes less room than the running footprint.
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 frame length plus the rounded ends.
A standard grounded 120 V, 60 Hz household outlet. The compressor has no on/off switch; you plug it in to start and it runs the whole session. First inflation takes 10 to 20 minutes. Keep the compressor running for the entire session, and if power stops, open the deflate valve, depressurize, and exit.
No. The oxygen kit is included: valve, hose, mask, and 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, and RecovAthlete asks for the chamber and concentrator on one prescription.
Federal law restricts sale of this device to the order of a physician, dentist, or other qualified professional, so RecovAthlete cannot release the C4-27 until the prescription is verified. You may place your order first. If you have no prescriber, Dr. Garry Warner offers HBOT consults by telehealth at (303) 915-4813, drgarrywarner.com. His fee is paid to him directly. Email your prescription to info@recovathlete.com.
We ship Newtowne chambers within the US only. For Canadian buyers, we ship to the UPS Store nearest you on the US side of the border, and 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 in the manuals tab.
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 upgrades tab. The owner pays shipping to and from the factory for warranty work. 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.
The C4-27 is pressurized with room air only, never oxygen, and has two chamber relief valves plus a compressor relief valve and a power outage alarm. Keep the compressor running for the whole session, do not bring electrical or static-producing devices inside, and do not open the zippers until the material is soft. Follow the Newtowne manual on clothing, permitted items, cleaning, and supervision.
Newtowne's manual lists conditions where the chamber should not be used, or only after a doctor clears you: a cold or flu, blocked Eustachian tubes, anything blocking the outer ear canal, signs of decompression sickness, being under the influence of alcohol, exposure to high CO2, pregnancy (consult your physician), and COPD with existing oxygen dependence. This is Newtowne's list, not medical advice from RecovAthlete. Clear any condition with your prescriber before you use the chamber.
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.
