    So I’m looking to get a arb twin air compressor and I wanna do a “wifey” inspired system by @ragofabrication. I’m buying their mounting brackets. I’m piecing all of it together myself cuz I’m gonna mod it a little differently by adding a air tank and possibly mount the compressor in the cab but hidden. I was thinking putting it in the little back cubby but idk how loud is it or how much air flow does it need. Does anyone know if the arb twin air compressor comes with that nice deflator on the manifold? I can’t find one anywhere or the name of it. Any information would be awesome. Thank you very much in advance.

    Heat Heat and Heat the compressor in a tiny space is going to get hot.

    the act of compressing air generates heat that is the cause of all the moisture in air lines

    If you plan on installing in that location your going to need a way to move cool air in and the hot air out

    Noise I would not want to sit in the truck while someone aired up a tire.

    My compressor is under the hood that is loud enough.

    Deflate do you mean a blow off valve or valve to drain the system or just a quick connect fitting ??

    Common misconception.

    Air compressors can only inhale the humidity in the air. The compression to make the increased pressure raises the dew point temperature of the air. When the hot, compressed air cools below the dew point temperature, then water will condense inside the air receiver. The air receiver must be drained of condensate to keep the air lines dry.

    Don't just get any tank for the air compressor. It needs to have a pressure relief valve, a condensate drain and be rated to at least 2X the maximum working pressure from the compressor. Pressure relief valve needs to be sized at a relief pressure less than tank's rated pressure and be able to pass the compressor's air flow.

    Yes, its only air. Ever see the aftermath of a air receiver failure?? Its devastatingly awesome and scary. Google air receiver failures. It is an UGLY event.

    It may be a blow off valve. I’m not sure. Definitely not the quick connect or a pressure release valve. I probably won’t do inside the cab then. I was just intrigued if it was something to look into.

    Thank you for more info. I didn’t realize the tank mattered that much. I planned on putting pressure releases where necessary. I was thinking about getting a seamless tank. I found them for air ride, I believe. I was thinking of tucking it in the rear wheel well if it’s possible for a air tools. I want it all to be the best and most functional. It will hardly get used. I enjoy building crazy shit and blowing peoples minds.

    It's not a "blow off valve" either. I've seen them a few. It's the blue drain valve sold in "the wifey" from @ragofabrication . It's the blue drain valve on the manifold in their kit.

    No worries I'm planning out my install.

    I think I found a way to not lose use of the additional port on the top of the manifold. Using a rear entry gauge and a 90deg 1/4npt fitting.

    I didn't know how I was gonna plumb mine right now but I was thinking about getting a manifold with a few extra ports. I'm not sure how I'm gonna lay it out. I like to do crazy stuff.
