Always have the underwater air supply you need for those practical jobs, with no need for tank fills or wearing 50 lbs. of gear on your back. This high-quality, continuous duty air compressor, as with all of The Air Line by J Sink's hookah dive compressors, is made by Thomas Industries for distribution to the dive market only. The hookah diving system has been tested and meets Compressed Gas Association Grade-E breathable air standards. Comes as a complete one diver system up to 60 feet depth, but will accept a second diver to 25 feet depth in a working environment. A second diver may be added by purchasing one of our Add A Diver kits, that includes everything needed to add another diver to our systems.
