A diving air compressor is a breathing air compressor that can provide breathing air directly to a surface-supplied diver, or fill diving cylinders with high-pressure air pure enough to be used as a hyperbaric breathing gas. A low pressure diving air compressor usually has a delivery pressure of up to 30 bar, which is regulated to suit the ...
Two types of diving spread are in common use: Air spreads for surface oriented diving operations, where the divers are deployed from normal atmospheric pressure, and decompressed back to atmospheric pressure at the end of the dive, either in-water, or in a chamber for surface decompression, using compressed air as the primary breathing gas, and ...
