FDA-Cleared, Portable Hyperbaric Chamber for Home and Wellness Use
Newtowne’s C4-40 Hyperbaric = Clinical-Grade Comfort & Maximum Space
Experience recovery, wellness, and comfort in the largest residential mild hyperbaric chamber on the market. The Newtowne Hyperbarics C4-40 is an FDA-cleared Class II portable class 4 mild monoplace chamber engineered for home use, clinics, and wellness centers. Crafted from double laminated ballistic grade nylon with welded bulkheads and a buckles exterior steel frame, it’s built for long-term durability and safety. The chamber runs on just 200 watts for energy-efficient operation. This class 4 mild hyperbaric chamber features hypoallergenic medical grade material, including 46 oz heavy-duty, double-laminated ballistic-grade nylon, making it ideal for long-term wellness routines and sensitive users. Additionally, it includes exclusive port pressure covers that prevent 'bug-eye' effects, enhancing safety and stability during use.
At 40" in diameter and 9 feet in length, this Newtowne Hyperbarics 40" chamber is the company’s most spacious model — perfect for individuals who value roominess or want to share sessions with a partner, child, or caregiver. The semi-translucent white interior and large reinforced windows reduce claustrophobia, while the 4" contoured Fortis memory foam mattress ensures comfortable overnight therapy. Side or top entry, floor-level access, and the exclusive dual safety zippers, custom airtight zipper, and triple zipper entry system provide seamless, self-managed operation. Additionally, the chamber features large view ports and precise pressure gauges for easy monitoring during sessions.
This mild hyperbaric chamber rests on a reinforced steel frame that requires no stabilizers. In some setups, the chamber may be slightly elevated for easier access. The 120L whisper-quiet compressor, along with in-line air filtration, creates a calm and hygienic environment. Exclusive port pressure covers prevent bulging and offer extra safety assurance during sessions, ensuring a secure and stable experience. The chamber also includes a session duration timer, allowing users to easily track their therapy time.
With over 20 years of manufacturing expertise, Newtowne continues to lead in affordable, medical-grade hyperbarics. The C4-40 comes with flexible payment plans, a 2-year standard warranty (with extended warranty options), and special military and first responder discounts. Military personnel can receive discounts on rentals, purchases, or lease-to-own hyperbaric chambers.

Newtowne Hyperbarics C4 40 FAQ'S
1. Is the Newtowne C4-40 too large for a single user?
Not at all. The 40" diameter provides extra comfort, allows you to sit upright, and reduces feelings of claustrophobia. Even for solo users, it’s a worthwhile upgrade — and perfect if a family member or child may join later.
2. Can two people use the chamber at once?
Yes. The C4-40 is large enough to accommodate two adults or an adult and child, making it ideal for shared use, families, or caregivers.
3. How does the C4-40 compare to other Newtowne models or brands like Summit to Sea?
While both brands are respected, Newtowne's buckles exterior steel frame, triple zipper entry system, and exclusive dual safety zippers make the C4-40 more durable and easier to operate. It also offers more interior space than smaller models like the C4-27.
4. Is the C4-40 safe to use at home?
Yes. It’s an FDA-cleared class 4 mild hyperbaric chamber with a 100% safety record. Follow the manual, secure all zippers, and ensure proper airflow. Always consult your physician before starting therapy.
5. What is included with the purchase?
Your order includes the chamber, buckles exterior steel frame, 120L compressor, 4" memory foam mattress, hoses, and precise pressure gauges.
Note: Oxygen concentrator is sold separately.
6. How long does it take to see results from HBOT?
Some users feel improvements within a few sessions. For most, 40 sessions lasting 60–90 minutes are recommended for measurable benefits. Results vary, but consistency is key.
7. How loud is the compressor?
It’s whisper-quiet — comparable to a home air purifier. Most users find it non-disruptive, especially when placed on a soft mat to reduce vibrations.
8. What warranty is included?
The C4-40 includes a 2-year standard warranty, with extended warranty options available. It covers material defects and workmanship.

FDA Compliance & Product Use Disclaimer
At RecovAthlete, we are deeply committed to transparency. We believe in empowering you with the information you need to make informed decisions. Some products are FDA-cleared, while others are not intended or marketed as FDA-approved medical devices.
FDA-Cleared vs. FDA-Registered vs. Non-Approved Products
Our selection includes recovery and wellness equipment that has received FDA clearance for specific medical uses. These products have undergone safety and effectiveness evaluations by the FDA.
Other items — such as soft hyperbaric chambers and performance technologies — may be FDA-registered but not FDA-cleared.
FDA registration means the manufacturer has notified the FDA of the product's existence.
It does not imply approval, endorsement, or evaluation for medical use.
In contrast, FDA clearance (or approval) means the product has passed FDA review for its intended medical claims.
Hyperbaric Chambers & Off-Label Use
The FDA has cleared soft hyperbaric chambers operating at 1.3 ATA only for treating altitude sickness.
Using these chambers for other purposes — such as general wellness, athletic recovery, or chronic condition management — is considered off-label.
Off-label use is not illegal, but it means the product's safety or effectiveness for that use has not been evaluated by the FDA, even if the chamber is FDA-registered.
Chambers operating at 1.4 to 2.0 ATA, especially hard-shell models, may be considered Class II medical devices and require a prescription and PVHO-1 compliance for legal sale and use in the U.S.
No Medical Claims
Unless explicitly stated otherwise for specific FDA-cleared products:
The FDA has not evaluated the products or statements on RecovAthlete.com.
Our products are not intended to diagnose, treat, cure, or prevent any disease.
All information provided is for educational and informational purposes, not a substitute for medical advice.
Consult a Healthcare Professional
We strongly encourage you to consult with a licensed healthcare provider before:
Starting any new recovery or wellness regimen
Using any equipment sold on our site for medical purposes
Treating existing conditions or symptoms
This is especially important if you are:
- Pregnant
- Managing a pre-existing medical condition
-
Taking prescription medications
Results May Vary
Individual results will vary depending on your health, product use, and other lifestyle factors.
We do not make any claims of guaranteed results.
Limitation of Liability
RecovAthlete and its affiliates are not liable for any harm, injury, or adverse outcome resulting from using or misusing our products.
