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

Dont forget if you ran out of air at 6 feet and held your breath on the way up in a panic you will most likely be in a serious world of hurt. If you dont know what im talking about look up Boyles law and Pulmonary Overinflation.

True, but if you can't do a free ascent from 6 feet, you should not be using diving equipment either. Or 10 feet or 20 feet or even 30 feet in my view. That's just me though.

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

Not related to last post, just a thought:
When you free ascend you take in air at sea level so it would be impossible to cause issues like you would see with tank or hookah diving. I think that is the biggest risk with hookah diving without a diving cert, you really need to understand the problems that can occur if you hold your breath on ascent. My dive instructor did the classic example of a balloon filled at depth then released to the surface. It got the point across well.

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

I have a Brownies. Dumped the float and base, put it in the dinghy, much less stuff to store and carry around. Friends use a $130 generator ,hooked up to a $149 oil less compressor for hull cleaning. Works well. Raise the air intake as high as possible on an extension tube. A snorkel with a purge valve works as well as a regulator. Old Johnson Air buoys used that principle.

I'm not being picky, but this statement is technically wrong and dangerous. A free ascent is defined as: "An emergency procedure used to return to the surface. The diver swims or floats to the surface while breathing all the way up." If you hold your breath at any time during a free ascent you are placing yourself in harms way. The balloon example is a good one and if nothing else highlights why no one should use compressed air diving equipment without proper instruction in it's use. Which I think was the point of this post, but unfortunately the wrong term was used.

Free diving is when you take your breath at the surface, hold it, and dive to depth, then return to the surface still holding your breath. In this scenario, there is no danger of an embolism since compressed gases were not introduced into the lungs.

I think we can all now agree that diving in the absence of proper training is a very dangerous thing to do. I think we can also agree that building ones own diving rig is not small undertaking and care must be taken to use equipment and materials that are up to the intended task. Beyond that, I also think we are, at this point, beating a dead horse.

A GREAT piece of equipment! However, it is designed for commercial divers and this thread is all about hooka diving. Most of the people here are just doing a little light maintenance like hull wipe, inspecting or zinc changes. or maybe they are more interested in looking at pretty fish.

You, on the other hand are a working guy and diving is basically your way of getting to work.

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.

All commercially-available, recreational-level hookahs are based on repurposed oilless air compressors and they are 100% safe for surface supplied air. Virtually the entire hull cleaning industry uses them and has for decades. I have been using various rigs I've built myself for over 18 years and 20,000+ dives. To infer that it is unsafe to use any air source that hasn't been vetted by the hard hat commercial dive industry is ludicrous. The guy is talking about cleaning his boat bottom, for Christ's sake. He doesn't need an $8000 diesel compressor.

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

My limited understanding is that all of the modern "oil-less" compressors are in fact oil free (except possibly manufacturing/machining traces) because they use teflon rings instead of oiled ones. And that is why the small tire-inflator types easily overheat and burn out, from the teflon melting if they are run too long.

Not a question of oil type of quality, just a different piece of equipment that simply does not use oil at all, so it can't contaminate the airflow.

Assuming it has properly cleaned of manufacturing traces during assembly.
