Napa Air Compressor ? Which one ? One of the small 12v ones ? AFAIK there's only 2 main players in the offroad on board air industry; ARB and Viair.

I, like many others, mounted an ARB twin under there using 589fabs mounting bracket. It airs up my 265/70s (31") very quickly and will air up 285/70 (33") or 315/70s (34.5") just as easily.

How To: ARB Twin Compressor install | 589fab mounting...

Obligatory not affiliated with 589fab or ARB, I bought all of this myself, none of it was provided to me, etc... Time required: 4-6hrs Tools used: Loooooots of patience (couldn't find a link, maybe someone can post one up for me) My trusty ATD Saber Under Hood light Lots of 1/4" drive sockets...

I do know about the ARB Twin, even single set up on there. After a lot of research, the Napa twin compressor put performs the ARB twin and is only around $100. I understand that you get the small form factor with the ARB.

I just want to see if anyone made a bracket under the tank before I start cutting cardboard to make one.

thanks for the input!

Can anyone who has it confirm that it’s oil-less and can be ran mounted on its side?

I’m looking to run it under the coolant tank and have it switched to my Auxbeam 8 Gang, maybe adding a couple fans to kick on with it pointing at the cooling towers? I plan to have my female hose fitting under the hood, forcing me to have the hood open and I will always run it with the engine running.

Just picked mine up.

Here are the specs that are on the box.

The 90 Amps is a big bummer for me because I wanted it wired to my switch panel. But I’ll just get the ARB coupler kit and a rocker switch for under the hood. I’ll use it once a month or so, so I’ll let y’all know if if craps out on my when mounted on its side under the coolant tank.

I don't see why you wouldn't be able to wire it through your switch panel using a relay to trigger it.

Do you mind explaining how I could go about doing this. I have an open 30 amp location on my switch. I’m not too familiar with adding relays.

Thanks!

A relay is nothing more than a switch, operated by another switch. You use a low amperage switch to energize the relay which then switches on or off a much higher amp item, such as lights. So you could use a low amp switch to turn on a relay that, when turned on or engaged, would turn on the compressor. The problem you might encounter would be finding a relay large enough for the compressor, which has a running load of 90 amps, thus would require a relay rated at a minimum of 100 amps (assuming the relay has a 10% +/- tolerance). The relay also has to be rated for continuous duty. Here's one here that should work:

100 Amp Continuous Duty Relay

To recap, you would run a feed line from your open location to a switch, that would in turn run to the relay to power the compressor. The link above doesn't state the relay amp energizing needs, but I would start at 10 amps, though it may only be 5. Wiring would look like this:

This is a simplistic drawing and doesn't show a 100 amp fuse or circuit breaker that should be mounted at the battery. You also need to use the proper size wire for all connections.

Thank you! The Auxbeam 8 Gang has relays built in it. This won’t hurt your diagram would it?

Why not just unplug the wires from the compressors on/off switch, and extend them to your switch? No need for a relay at all.

Or am I missing something? Keep it simple.

The compressor is rated at 90 amps. My switch has a fuse panel with a zone rated for 30 amps and then a breaker in line to my battery rated at 60amps.

So now I need to add a relay rated for 90+amps in line to my fuse panel.

Thanks everyone!

Here's the switch in the compressor. You can see it's NOT a 90A switch. It is just a standard duty switch. There are already 2 relays on the circuit board in the compressor. View attachment 420872

Disconnect the original switch, extend the wires to your switch and be done. Keep it simple.

Beautiful. Thank you!
