Air Compressor Options

[BillWorkbench]

I have two recommendations for ya.

1. SmittyBilt 2781 5.65 CFM air compressor: https://amzn.to/3qlhQ1r With my stock tires it takes longer to air down than to air back up from 20psi.

2. Redline Tuning hood QuickLift. https://www.redlinetuning.com/SearchResults.asp?Search=Jeep+Wrangler+2020

I opted for the ARB twin compressor, and hardwired it to only be able to operate when the jeep is running and charging. It has a 100% duty cycle rating, is completely self contained, and it's only limitation to producing compressed air is the amount of fuel in my gas tank.

It's not as fast as a power tank, but my thoughts are that if I'm airing down it's because I'm enjoying a day off. My days off are for not having to be in a rush. Also, I'm not a big fan of driving around all the time with a pressurized container in the cabin with me. Yes, it can be taken out but than it only serves an off road benefit. So far, I've been able to help 3 different people get off the side of the road, and only 1 of them needed one of my tire plugs. Other ones were a spare tire that was never inflated, and a slow leaker from a bent rim.

I wanted something portable and liked the ARB compressors, so I purchased the ARB CKMP12. Only used it in the driveway, but it seems to work well enough for my needs. https://www.amazon.com/ARB-CKMP12-Performance-Portable-Compressor/dp/B004P9A35E

If you have the trailer group, consider this. The 400/400p run on 30A. You can do this so you don’t have to pop the hood to air up. It is a 30A line to the 7 pin connector.

Came across this thread and your post. Just did this with my portable air compressor. Brilliant yet simple idea. Thank you.

I’m happy I could contribute!

I have an ARB twin hardwired under my passenger seat . Takes about 8 minutes from 10-35 psi on goodyear Mtr 40s . I have a custom hose with 4 quick connectors that do all four tires at the same time . While the tires are filling , I look under the jeep to see what I tore up .

In my CJ buggy I have a Power Tank and dual ARB. When we went to Silverton CO this summer I took the PT with me and it served me well. PT has a JL specific kit that looked nice so I bought one. Installed it today, very satisfied.

Similar setup but only 5 minutes for 35's from 15 to 32psi. Really happy with it under the seat as it takes up no usable interior space. I also did up a custom 4 chuck setup to inflate and deflate but can easily run a single chuck to help those in need.

My son now looks after deflate/inflate when at the ORP.

Does anyone run a onboard air setup that has a hard mounted tank and compressors? I have a dual compressor setup that I’m trying to decide between my 91 YJ or the 20 Sahara to get it installed.

Danny and @Some Random Guy, is this 30 amp circuit at the trailer hitch switched with the ignition? If not I may also use it to quickly hook up my trickle charger. I was planning on running a 40 amp circuit from the battery to the front bumper for the charger/compressor but this circuit at the hitch may work just as well.

It is only hot when on, so with the ignition. I’m confused about the trickle charger. What are you trying to charge?

Just trying to keep the batteries topped off. I'd rather just plug in the charger than lift the hood and clamp to the battery posts. Thanks for your reply.

I have used a CO2 tank for reinflating over the last 18 years, it's as fast as using a large air compressor and can run air impact tools, something 12-volt compressors usually cannot do.
The CO2 system I use, from Polyperforamce, is much cheaper than a Powertank.

The 10-lb tank is refilled at a local homebrew store for $15-20, industrial gas supply shops can refill it too.
To know how much CO2 is available, I know the weight of a full and empty tank and carry a small travel weight scale for field measuring.
The tank is mounted, out of the way on the driver's side rear roll bar.
The tank is also useful for running air nailers and staplers on small field jobs where dragging in a compressor would be difficult.

I went with the ARB Twin mounted to a Grimm under-hood bracket, I did add additional heat shielding to the Grimm heat shield and also insulated all the air lines. So far, no heat related issues what so ever!

Smittybilt 2781 3 gallon tank, auto shutoff @ 140 psi, auto on @ 110 psi. Works great!
