I've got some literature on them back in the office.. seems pretty identical to the EA. A couple of customers run them with satisfactory results. I've seen them firsthand, looks like a decent unit. Mud member Kevin Patterson (on ExPo???) has a ton of experience with them, hes convinced they are a great unit.

The Extremeaire compressors get very hot. It is recommended to have it mounted in a well ventilated area, The first 16" inches of hose should be heat treated and be able to handle high heating conditions. On our install to a air tank we have 2 feet of heat tubing

I've been using a Warn Powerplant Dual Force HP with great success. It has a built in thermal overload which has never triggered. 100% duty cycle and as a bonus... it's a 9500# winch.

A friend and I bought 12v Puma compressors about 5 years ago and have had zero problems with them. They put out a good amount of air and have been very reliable.
At one point I "raced" my Puma against the MV50 from Kragen and several other similar compressors and the Puma was quite a bit quicker when filling a 33x12.5x5 tire. Unfortunately I didn't record the 15-35psi fill times so I don't have quantitative evidence to post here.
The only downside in my opinion is the size, I often carry my MV50 to save room. We've separated the tank and compressor on one of the Pumas and installed in on my friends XTerra with the regulator and switch under the hood and the compressor and tank where the spare tire used to go.
Based on my experience I'd highly recommend the Puma for the money.

How does the newer ARB high-output compressor do? It seems to have comparable specs to the Viair 440P, but I like the fact that its hard mounted and has a 50% duty cycle.
This is the only video I've seen of it, does anybody have real world experience with it though? I'd be filling up 35's.

*edit* East Coast Gear Supply's site states that the compressor will fill up a 35" tire at 8 psi/minute. That means about 4.5 minutes from 0 to 35 and about 2.5 minutes from 15 to 35. Seems to be on par with its competition. I think the selling point is going to be the duty cycle, not to mention the warranty and that it has a built in pressure switch (should work flawless with a tank).
The best price I have found so far is over at Northridge 4x4. $300 for the compressor, hose kit, and JK mounting bracket. I guess I could always turn around and sell the mounting bracket since I'd have to make my own.

i have this harbor freight model hard mounted under the hood. it works pretty good for me. i have 32" tires. it usually takes between 2-5 minutes per tire from 15 psi to 30 psi.

i still have a old CO2 fire extinguisher bottle i'm going to use as a tank, but i have not gotten around to messing with it yet. someday i may, but the compressor has been fine for the last two years.

I use a Puma 1066 w/o the factory tank, I have one of my rock rails set up to function as a tank. It's set up 85-105 psi for my ARB's. It is strong and works well.

i got my high output ARB CKMA12 from alljeep.com for well under $300.
it's used for my air lockers, but doubles as on board air... i guess. it's slow. i only have 33s and usually only air up to about 20psi, then drive to the nearest gas station and fill up the rest of the way.
my first compressor was warrantied because the conrod disconnected itself from the crankshaft. i don't know what the technical terms are, but anyway, ARB warrantied the part for me as soon as i sent them a pic of my part. they let me keep my compressor and sent me the ENTIRE unit, complete with wiring and everything.
they let me keep my part, with one request: they don't want to see my old "broken" compressor on ebay.
i don't regret buying this compressor, so long as i don't let myself believe that i bought it to air up tires. i like it for it's plug-and-play interface with ARB lockers, and for the great customer service associated with the brand.
if you want to do more than pump up an air locker, i suggest you go with something a little more robust.
LilKJ has a very nice unit for sale here on ExPo.

If its that slow for your 33's then it wont last for my 35's (going bigger in the future). I don't need it to actuate lockers, just tires. The $300 tag includes the compressor, air hose kit, and a jeep bracket. The bracket sells for ~$80, so I could probably get $50 for it. Either way, I'll have to look for something else.
Hi guys,
gonna post up on this one as it's pretty relevant. We had a problem with a small number of CKMA12's coming apart at the bottom of the connecting rod on very early build compressors back in 07. We learned about this which is part of the reason we handled the warranty claim with so few questions asked (hardware at the crank was uprated at this attachment point as a result). As it is the warranty failure rate on any of the CKMA12 units built in the last 18 months (and BTW, they are still machined and assembled in Australia) is extremely low, well under 1%. They are bombproof at present and you will not easily hurt one. Beyond that, the specs are based on early production models and have not been updated to this point online. Development has been ongoing and the numbers at tire inflation pressures are in reality double digit higher than those first units. I've been abusing an 08 built unit in my personal Jeep for better than a year and can't hurt it. Things like airing up my tires, my trailer tires, and my buddies tires in 90 degree weather just to see what happens and so far I haven't even been able to get the thermal shut down to engage. So take it as you will, but I am convinced that there is not a better compressor of this size on the market and if by chance a problem occurs please understand that we will stand behind it and get you fixed well making an effort to determine what caused the problem and how we can stop it from happening in the future.

Ha! I just sent an email through the ARB site regarding actual CFM rates. Is there any way you can get us an actual CFM rate at 90 PSI? Also, how easy is it to set up one of these units to an external air tank? Would the built in pressure switch work just fine or would I have to do some work to the system?

Marc, i complain that the compressor is "slow" only because i'm wary of breaking another compressor. i love your products and swear by them, but i'm just scared of getting caught out in the middle of nowhere without a compressor. is there any way i can check the build date of my warrantied compressor, or can you guaranty that the new compressor i received was of the newer, better generation?
i can live with airing up tires slowly, but the longer it takes, the more scared i am that it's about to go.
