Our multiplace M5200 hyperbaric hard chamber by far is the best available in this price range. We have no competition in the hyperbaric hard chamber space with this incredibly well-crafted system. Our system is unique in the industry of high-end hyperbarics as it does not require any special venting since the net room oxygen does not change as the unit is operated. Our system is still categorized as mild hyperbaric oxygen at 1.6 ATA and is much safer to operate than the more expensive systems that require oxygen tanks. Oxygen Health System’s multiple M5200 hyperbaric hard chambers are designed for safety, durability, comfort, and ease of entry and exit along with many more advanced features. This hyperbaric hard chamber system is designed for practitioners or home users who want a more advanced system that allows for higher pressurization in a hyperbaric therapy system and that also provides a simplified Two to Five users operation. Just power it up, get inside, and hit the button to start therapeutic sessions. Clients of all shapes and sizes will love this system for its expansive roominess and the luxury it can provide in an environment of everyday and all-day usage.
