Re: DIY - discussion on building a DIY hookah diving compressor

Really, dont ever use a normal air compressor for an air source. First off, commercial offshore diving services all use deisel dive compressors that have various engines (325, all the way up to 5120's) which the output in volume at depth is calculated by a very knowledgeable person. Second, they are specifically designed with water traps( air filters) to screen out that bad **** such as bugs, rust, you name it. Thirdly, they use two oils. One.for the engine that powers the air pistons and then a breathable synthetic oil for the actual lubrication of the pistons. You can buy seperate volume tanks, engines and compressors to piece them together which would be alot cheaper then paying 8 grand on a beat down 325.
Also. Another alternative would be just to get an airpack of hp bottles. You can rent whatever medium youd like however at 14 ft - 50 foot youll only need air, unless you do inwater deco stops using 02. Thats a whole nother ball park. Get yourself two hp bottles, have them professionally inspected. Then order 3/8' inch air hose for a dive umbilical. Youll need a air regulatlor for the bottle manifold and of course the second stage for your mouth. If you call divers supply in belle chase la they can tell exactly what you needs. The hp air bottle rack is always emergency air for divers offshore. This would be a more realistic way to surface supply dive without spending a fortune.
