Yeah, like I said. Recreational diver.

...how do monitor the air quality going down the hose? I just didn't like the idea of having passing boat exhaust or BBQ smoke getting pumped down to me...or holding tank fumes.
What precautions do hull cleaners take to avoid infection when diving in unpure (present of one-celled creatures) waters? Would think that marinas would have dirtier water than most.
And we both know that hull scrubbers are recreational divers with a scrub brush.Yeah, like I said. Recreational diver.

Guys I've had do the hulls on my boats in the Chesapeake have always come in a full wet suit and worked with gloves. All of them hosed themselves off after coming up from each boat. The only skin they had exposed was the small bit where their mask and regulator weren't covering. Never heard any issues regarding sickness from any of them.
They used lots of different implements, various scrapers, brushes and scrubbing pads. Some wore tanks, some used a hose(hookah?) setup off a tank. Don't recall any using a compressor driven rig. Several times I've heard them talk about how unevenly time seems to pass when under a larger boat. As in, they were down there longer than they thought, usually due to the reduced light thanks to the conditions in the Bay.
Me, I'll take a scrub brush and a suction handle to do a quick swipe around the boot stripe if we're out on anchor for a swim. But I leave the cleaning and zinc checking to the divers.

23+ years in the biz and over 30,000 service events performed in crowded marinas and I can count on two or three fingers the number of times I've even smelled exhaust in my air, much less having to ask an owner to shut off his engine. It's really a non-issue, IMHO.
Question … why would this matter?
I'd imagine the best aspect would be preventing small abrasions while doing the work. That and some marginal protection from anything floating about. Nothing "reasonable to wear" is going to protect them from 'everything' but that seems to be enough to satisfy their concerns.
And pardon me if I've used the wrong nomenclature describing what they were wearing. I'm not a diver, so calling it a 'wet suit' may or may not be accurate.
I am sure that the wet suit could aid in limiting any abrasions but not from things like dirty water, infections , or any one celled or larger pathogens.
Every recreational/light commercial level hookah you can buy is based on a compressor that was designed to do something else. Mrwesson is correct; there are no compressors designed specifically to provide breathing air and even in the most expensive, high end commercially-available hookahs, the compressor used in it can be bought off-the-shelf by you or me for under $500. So the answer to your question is, yes, there's a reason why you can spend a couple grand on a hookah. It's called "profit motive."
I have been building and earning my living with hookahs for over two decades. Every hookah I have ever put together has used the exact same compressors and hose/regulator assemblies you can find in expensive commercially-available rigs. Every bit as safe and reliable but for a fraction of the price. There is nothing special about the hookahs you buy. They all use components that anybody can easily source and purchase themselves, including the compressor.
BTW since you obviously know more than me about this stuff how do you feel about my setup..? it's kind of odd.
Oilfree 12v masterflow 1050 compressor(2.5cfm@90psi)
5 gallon aluminum tank with aluminum valve block
Water filter/separator
90psi electric shutoff valve
Breathing grade 50' line(no brainer there).
Hookahmax regulator
Never having used a 12-volt hookah, I can't speak about them from experience. But if it provides enough air for what you are doing, more power to you. The other components you are using are 100% standard.
A summer in Florida and your prop would look like a coulifiwrI pay Zero. And I do zero. I spend the winters in fresh water and the summer in salt. The unwanted growth is gone a couple days after the change.
Sorry. Dropped my phone and it posted.

In Naples FL it was about $2-2.50/ft. last I checked. Some areas the water requires divers to don a dry suit to avoid infections, so a bit more money there. ( a sewage plant discharging into the river) Also, we have a lot of mid-westerners who try to squeeze 18-2 months or more out of their paint(they don't seem to believe that conditions here require fresh paint annually for proper care). Divers will triple the charge or just refuse and refer them to the yard.
