OPM Viair 450C setup

[grapeismurder]

I just picked up the QPM for my 80 and I'd like see if you can help figure out how that rigs is oba air setup in the pictures Delta has on their site? I'm not certain where this tank is located or what size. Better yet, if I need a tank at all.

My vehicle is on 35s.

*Oh yeah, I have the Viair 450C too

I had that exact set up for years. My compressor was way older and was passed from vehicle to vehicle and I finally replaced it this year.

Tank. I use to run a tank but unless you have it for air lockers, it doesn't have anywhere near the capacity for it to do any real good. I haven't run a tank, forever.
I plumed my air hose down the corner and out to a fitting on the bumper. The braided line ran to a square manifold with a 90 psi cut off switch mounted just above where the compressor is. The switch controlled a relay and the relay controlled the compressor.

The braided hose can get quite warm. I'm sure it wouldn't burn anything but i spaced it above the wood. when I mounted it to the air block. I also ran air brake hose for the feed to the outside.

About that compressor. I bought it when they were first released. I cant tell you how many years I ran it but, it was alot. I finally wore it out. Talking to the VIair rep at a show, he was impressed on how long it lasted and said if I send him my info later, he would put together a rebuild kit if I wanted. I opted for a new compressor.

I have the trim panel installed so you cant see it. The heat from the compressor has never caused any issues.

Shoot. I really appreciate the help. Im not familiar with oba, or air lines but is the 90psi cutoff like a mechanical checkvalve or something more complicated?

Could i just connect directly to an open flow bit and use a switch and relay?

Thanks for the help!

In the picture, the two wires going to the air block looks like a cut out switch. The amount of current the compressor takes is too much for that switch if its not tied to a relay.

Could i just connect directly to an open flow bit and use a switch and relay?

Absolutely

Awesome. I appreciate the help. Last question: in the pictured setup, that uses just a sealed pressure switch on a T acting as a remote sensor to engage the compressor which is directly powered by a 50ish amp fuse and wire to the battery, or is this system also manually switch on/off?

Thanks again for the help!

sealed pressure switch

That's your cut off switch. Terminology will be the bane of your existence. So many diffrent names for the same thing.

Use that to control a relay. These compressors draw quite a bit of current and the switch wont last long. I use a 40 amp rated relay.
The compressor itself will have an on/off switch on it.
If your going to run it as a constant run system, just control it with the built in switch and ditch the pressure switch. On my system, I have a relay controlling the compressor. I have a remote switch on my drawer system to turn on the relay and when the air hits 90 psi, the compressor shuts off. Keep the system simple. Less parts to wear out.
