The OT-H401 is a single-occupant sitting hard shell hyperbaric chamber from Oxyboss, a factory-direct manufacturer since 2006. You sit upright, read, or work on a tablet while the chamber pressurises up to 2.0 ATA and the integrated 3-in-1 oxygen source delivers 10 L\/min at 90% \u00b1 3% O\u2082 through a face mask. The 5083-aluminum shell is built to ASME PVHO-1 design criteria, factory-tested for 5\u20137 continuous days, and ships as one chamber plus a separate oxygen-source crate.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The 3-in-1 oxygen source is the part you most often underestimate. On most hard-shell chambers, “oxygen system” means three or four separate boxes \u2014 concentrator, compressor, air conditioner, cabling \u2014 that you source, install, and warranty yourself. The OT-H401 sitting hard shell hyperbaric chamber ships with all three modules pre-integrated in one chassis, in one crate, under one Oxyboss warranty.

\n\t\t\t\t\t\tA 90-minute session inside a sealed pressure vessel with you breathing through a mask builds heat fast.
