The 30-inch OHS hard shell is the cheapest 2.0 ATA steel chamber we found, at $35,490 on the OHS chamber finder.
It keeps the 36-inch model's oxygen system, safety list and three-year warranty, and OHS says it fits through a standard 35-inch doorway.
Thirty inches is snug for broad-shouldered adults, and as with the 36, there is no FDA statement for the chamber.
Best for: the lowest price on a 2.0 ATA steel hard shell, and it fits a standard doorway.
In the box: 2.5 mm 304 stainless steel shell, soft mattress and pillow, oxygen system; 507 lbs; fits a standard 35-inch doorway (OHS).
The catch: At 30 inches it is narrower than most soft chambers, the system weighs 507 lbs, and FDA status for the chamber is not stated.
OHS lists the 30-inch at $35,490 on its chamber finder, the lowest-priced 2.0 ATA hard shell it sells. It comes with a 2.5 mm 304 stainless steel shell, a soft mattress and pillow and the oxygen system. Financing is available. Shipping is not stated.
Hard shells do not fold. OHS says this one fits a standard 35-inch doorway, which saves a lot of trouble in older houses and apartments. The trade-off is width: 30 inches inside is narrower than the 32-inch Vitaeris and the 36-inch Skybaric soft chambers. Lie in a 30-inch space (two chairs and a tape measure will do) before you commit.
You can choose 1.3, 1.6, 1.8 or 2.0 ATA. OHS lists an internal emergency release, interior and exterior emergency relief valves, an emergency alarm and interior and exterior controls.
