Just picked up an air bottle-need advise on a regulator

I just acquired a recently retired SCBA air bottle from the volunteer fire department that I am in and I am looking for suggestions on how to regulate the pressure down to a usable level for airing up tires after trail riding and any other uses. Any suggestions?

You can get an adjustable regulator like you would use on an air compressor. Napa has them.

I am not sure that Napa will have a regulator that will handle that kind of pressure. Those bottles are rated up to around 2600 psi.

The bottles might be rated to 2600 psi., but how much air will you be able to put in them ?

Do you plan on putting that kind of air in it? Carrying 200 psi would be plenty to air up.

They are typically filled to that. I will refill it at the firehouse.

Holliewood, I am not sure if it will always be filled to capacity, but I want a regulator that won't explode if I do fill it up toward the high end. It would be nice to be able to run an air impact or use an airbag to help lift or upright a jeep in case of a roll over.

I don't think that tank will be capable of what you think it is. It may be pressurized to 2600 psi but it only holds a small volume. Air tools are rated by flow rate at a given psi. So although it can hold high pressure it won't have the volume to maintain the flow required to operate such things.......at least that's my understanding.......for what that's worth, lol

Jeepwhore, you are probably right about that, so running air tools may not be in the cards, but the volume will run an airbag if needed, as that is what we use on our rescue in the department.

If you're wanting to run air tools and such an oba system would be a better option I believe. as stated above I also don't believe you will have the volume to use it the way you would like

Oh well, I guess that I will just have to be careful not to overfill, so I can use a compressor regulator, unless I can find something at a welding supply that will run higher pressures. Not really planning on running air tools, but thought it might be an interesting option.

You will also need a drain, and for safety and a 'pop-off' valve at about 150psi.
You will also need an electric pressure switch.

An electric pressure switch on an air tank? This is essentially like a CO2 tank, but with atmospheric air instead (assuming that's what the firehouse uses) compressed by a specialty tank pump that fire departments use to refill their breathing tanks.

Unless you have it filled to the pressures it's capable of the volume will be so slight that it will be pretty useless.

Yeah, I am going to need a regulator that can handle up to 2500 psi.

Those are the pressures that CO2 tanks see, but the CO2 is pressurized into a liquid in the tank and a regulator for that use probably won't work.
