Portable Air

Other than the obvious ARB unit, or the like in price, what portable compressors have you had good luck with?
 
For the Viair, what model do you recommend for periodic tire inflation and maintenance? I assume the 70P but the website is a bit limited as a configurator.

The 88P has 4.5 stars on Amazon. I was wondering if anyone would point out this brand. Seems a good price if it works without breaking, even if it is slow.

I’ll check what model I have when I get home Thursday. The one I have is plenty fast for post trail air ups.

I have been thinking about a Power Tank instead of a compressor unit. For me I see a few good options with a high pressure portable tank. One being able to switch from one rig to another and faster fill up times.

I'll put my Puma up for the pepsi challenge with any and all of these and I think it is the best bang for the buck, by far.
I got mine from compressor source on ebay but you can even find them on Amazon. https://www.ebay.com/itm/PUMA-12-Volt-DC-1-5-Gallon-3-4-HP-Oil-Less-Air-Compressor-Portable-High-3-4-CFM-/291533189664?hash=item43e0bb7220

There are plenty of comparisons between compressors, particularly these. They have a bit of a following now... And when I say bang for the buck, I am saying a much bigger bang. I want those tires inflated lickedy split---

One last thing--they also sell just the compressor for a little less. But it doesn't come with the pressure on/off regulator, so to me, I'd just buy the one with the tank and disassemble if you want--still come out ahead. Personally, I just mounted the compressor behind the drivers seat/cubby and all is good. 255/85's go from 15lbs to 32.5 lbs in 60 seconds. Not bad.

This conversation was started because I’m thinking I need a compressor, but that’s because I had lost the Q Industries pump that I bought at Costco about ten years ago, when we moved to this house about seven years ago. But with my mind on the topic, I started thinking that there’s no way I had actually lost the thing, and one way or another I actually dug the thing out of three layers deep of storage under the house.

And it actually works.

I deflated one of my 235 tires down to 20 PSI (easy to do with the connector on the hose) and refilled to 40 PSI in about 1:30. So I suppose I have to say I’d recommend the Q Industries pump.

I can’t imagine I spent as much on this as what it is currently listed for on Amazon right now. But one way or another, I’m covered for now. LOL!

If I were to do it over again, I would probably get an ARB rather than a Viair. The Viair (at least the one I have) doesn't have a pressure switch, so if you're using it to air up tires, you need to use the Viair tire chuck. The tire inflation kit from Viair is complete garbage. At some point I'll get around to adding a pressure switch so I can use the ARB air hose kit which is really good quality.

Only externally mounted outlet I've seen was positioned on the headlight surround. One RRC buddy has one of those super flows mounted under the hood.

I'm mounting a ARB High Output CKMA12 in the seat box of our 90 to operate lockers. Have an old RRC air ride suspension tank. I was thinking of plumbing the compressor into the tank so there is enough air for bursts with an impact etc. Question is, what do folks do about moisture with these onboard systems. Typically air thats been compressed to 150psi is around 300 degree's as it leaves the compressor head which means condensation. We have had 5 ft of rain here in the past 6 mos, Virginia is very humid these days.
Have used a 20lb co2 tank for a decade and a half but the lockers are forcing a change.

Yes, all compressed air is water saturated, regardless of where you live. It is not normally a problem with filling tires. Frozen lines are the only real issue. Drain the tank on occasion. I would only work on a more complex system if you were trying to setup air suspension.

I was also looking at the tank on the LWB that's just sitting their with nothing to do. But I'm not sure it's worth the trouble to figure out a system like that yet. Having the hand held pump that I can just walk around the vehicle with will suit me fine for a while. I'd like to know what others have used that tank for.

My brother bought a Jeg's tank to carry in his vehicle, but it only has capacity to reinflate two tires back from 15 PSI to standard road PSI, so I would think the small tank from a RRC wouldn't have much punch.
