The Perfect Balance of Comfort, Space, and Performance.

Experience the next level of recovery and wellness at home with the C4-34 Mild Hyperbaric Chamber, Newtowne Hyperbarics’ most popular and versatile model. Engineered to comfortably accommodate a larger adult—or a parent and young child—this chamber combines generous interior space with medical-grade construction, ensuring every session is as safe as it is restorative.

Built entirely in the USA and cleared by the FDA, the C4-34 represents the gold standard in mild hyperbaric technology. Whether used for personal recovery, performance optimization, or general wellness, it delivers clinical-quality results in the comfort of your own space.

Crafted from 46 oz. heavy-duty, double-laminated ballistic-grade nylon, the C4-34 is built for long-term durability and safety. Its reinforced steel external frame provides unmatched stability without the need for extra supports, while its white interior and dual viewports create a calming, open atmosphere to reduce any feeling of confinement.

With intuitive internal and external controls, users can easily operate the chamber independently, while a quiet, energy-efficient compressor system ensures a smooth and relaxing experience every time.

Each chamber includes a 2-year comprehensive parts warranty, extendable up to five years, and comes standard with an oxygen kit and contoured 4-inch comfort mattress for a premium experience right out of the box.
