I've done the electric compressor thing and it just takes weay too long compared to the "scuba" tank compressed air method. Today i was given a scuba tank it came with them bc, a air gage and a air "chuck" quick release thing(can't remember what you call it). I know it would be that hard to covert to what I want but I just what to do it right the first time. Does anyone have a link or something showing/telling what I need to do?

normal "scuba" tank systems are liquid CO2 tanks that are filled at the local welding shop.

Dont know if a scuba tank can take CO2.

 

I've made a version of my 4Air tire inflator that worked with a Scuba tank. You just need the regulator(s) and the fitting, I think the mating fitting sue 1/4" NPT thread. The main things with Scuba tanks are that you often need to be Scuba certified to have a tank filled (and the tank needs to be certified - might be why you got it for free, and you need a good protection cage around the regulators and some way to strap it down very well.

 

Roger thank thats what I was looking for. The guy I got it from I work for and he is diver. He is switching to aluminum tanks. He said I may have a problem refilling it but if I do he can get it done for me. He just said I needed to get the tank tumbled but I put it to use.

Your 2air(110" kit) is to air up 2 tires at a time instead of 4 correct?

Correct, inflates or deflated 2 tires on one side of the truck at the same time.

 

Compressed air (or nitrogen) vs. CO2 has been covered extensively, but to recap it, your SCUBA tank has several disadvantages, the worst being it's lack of capacity. At 300PSI a standard tank holds 80 Cubic/Ft of air. That's less than half the 180 cubic/ft of a 20 LB CO2 tank. I'd be surprised if it'll air up more than 10 large tires per fill.

To me the biggest problem is the pressure...God help ya if you ever have a valve get knocked off a SCUBA tank. It won't burst, but it'll sure be bouncing around inside your rig...
