Recently I installed a siege engineering oba setup on my truck, and a rear ARB locker. The siege engineering tank and pressure switch are setup to run at 150-180 psi. The ARB locker needs between 85-105 psi to operate, too much pressure may damage the ARB and void any warranty. So.... I need a regulator to control the pressure. My question is, where can I find a suitable air regulator and what have other people used? From my initial experiments a in-line regulator such as one used for an impact wrench would not be suitable as it only controls pressure at flow and does not control static pressure. Or am I missing something?

 

Ok, my main reason for posting was to see if anyone had a solution that was "off the shelf" like from Home Depot or the like. Talked to a guy from a welding supply shop and he is pretty confident that he can get something that will work... just don't want to wait a week for the part to come in.

 

Damn, what a loser! Who responds to their own thread?

 

I bought a regulator at lowes. you can get them with or without an air/water separator. I would recommend you get one with.

even though it has no filter, one like this will work. drop by your nearest lowes or home depot and you'll find em.

I use one similar to that one for my air horns. my system pressure is normally around 110 but i run my horns at 60-80 psi

 

tried that, doesn't control STATIC pressure, just pressure at flow.

 

The only static pressure reg's I work with are wall mounted for shop air here in the maint. bay. Can't recall seeing portable ones, although I'm sure they make 'em good luck!

 

Well, I would guess you know more about these things than I do.....but perhaps you're over-thinking this?

All I know is from my experience with my own compressor at home. My compressor is setup with a pressure cutoff switch that's measuring the pressure in the tank. It also has a pressure gauge on the tank. Then it has a regulator like the ones linked above, I believe, for the output.

Now, let's take for example, filling up the tires on my mountain bike. I turn on the compressor and it fills to 120psi. Then I set the regulator for 40psi. Now if I fill up my tires to the point where no more air is flowing from the compressor into the tire I have 40psi in the tire and not 120psi - it'd probably explode if I put 120psi in it! Why wouldn't the same thing happen with the air-locker?

Ok, moral of the story is don't be cheap. Went back to Lowes and bought a self-releiving type regulator and... it works great. Finally had everything working with no leaks. Went to the local mudhole, didn't even need to lock the front hubs. Whoo-hoo!!!
