Sechrist 3300H
The narrowest and lightest of Sechrist's three monoplace chambers, and the only one whose 700-pound patient rating is an upgrade rather than standard equipment. It is also the only H model whose relief valves are set a pound lower than its siblings', so a valve is not interchangeable across the line.

Key features
- Smallest and lightest chamber in the H line at 32.50 in internal diameter and 2,030 lb, which makes it the easiest of the three to site
- Rated for 500 lb patients as standard — the 700 lb rating its two siblings carry as standard is a paid upgrade on this model
- Two relief valves set at 35.0 psig, one pound below the 3600H and 4100H setting; valves are not interchangeable between H models
- Two independent emergency vent systems, technician-controlled and automatic, each decompressing 30 psig to 0 in under 120 seconds
- Purge flow adjusts from 80 lpm to at least 450 lpm at 15 psig chamber pressure — Sechrist's oxygen-conservation control
- Door Lock Indicator gives visual confirmation the safety lock pin is engaged without the operator having to bend down to check
