Product Benefits

The Newtowne Hyperbarics C4-40 is the largest residential mild hyperbaric chamber Newtowne makes — and the most comfortable hard-shell option available for home HBOT. At 40 inches in diameter and 9 feet long, this FDA-cleared Class II portable hyperbaric chamber gives you room to lie flat, sit upright, or share a session with a second person. Designed for adults up to 6’3” and 250 lbs, it is built from double-laminated ballistic-grade nylon on a reinforced steel frame and engineered for daily home use without the space constraints or durability trade-offs of cheaper soft-shell chambers. If you want the best hyperbaric chamber for home use and you want it made in the USA, this is the chamber to buy.

Prescription required — A physician or chiropractor prescription is needed to purchase this chamber. See the prescription guidance section below. Need one fast? Dr. Garry Warner offers telehealth HBOT consults at support@goofitness.com.

Why GooFitness Carries the Newtowne C4-40

Newtowne is the only major hyperbaric chamber brand manufacturing in the United States — every other brand at this price point is built in China. After 20+ years in production, Newtowne's track record of zero safety incidents and direct factory support is what separates it from imported alternatives. We carry Newtowne because clients who need a chamber for serious, daily use need one that is going to hold pressure cleanly, support their weight comfortably, and not degrade after 100 sessions. The C4-40 is the choice when a buyer wants maximum space and USA build quality without paying clinical-grade prices. Our team can also help with prescription referrals, setup guidance, and ongoing support — not just the sale.

Who Typically Buys the C4-40

Athletes and coaches doing daily recovery protocols — the 9-foot length allows a full lie-flat session without compromise

Larger adults and taller users — the 40″ diameter and 9-foot length comfortably accommodate adults up to 6’3” and 250 lbs, where smaller models may feel tight

Families with a child or dependent who needs hyperbaric therapy — the 40″ diameter fits one adult plus a child comfortably

Clinics and wellness centers that want a residential chamber at a fraction of multi-place clinical hardware costs

Buyers upgrading from a smaller soft-shell who want a hard-shell chamber with proper structure and better pressure consistency

Military veterans and first responders — Newtowne offers direct discounts to service members and families with proof of ID (ask at checkout)

What the C4-40 Delivers at 1.3 ATA

Pressurizes to 4 PSI (1.3 ATA) — the level cleared for mild HBOT general wellness use at home

Supports 60–90 minute sessions; a session timer is included for easy tracking

Works with prescription oxygen concentrators at 10 LPM @ 20 PSI to increase dissolved oxygen delivery

Four accessory valve ports allow oxygen monitoring, communication devices, or pass-through accessories

FDA-cleared Class II medical device, clearance #1000402893 — same regulatory status as chambers used in outpatient wellness clinics

Two 9″ reinforced viewing windows — one at the head, one at the feet — reduce enclosed-space anxiety during sessions

120L whisper-quiet compressor with in-line air filtration keeps ambient noise below disruptive levels — comparable to a standard air purifier

Built-in power outage alarm sounds immediately if the compressor stops or power is interrupted — sufficient time to exit the chamber using normal procedures
