I would not use the standard ARB compressor for anything but powering the locker. First, ARB's standard locker compressors are not designed for the repeated long duty cycles required for refilling multiple big Jeep tires. That simply means they were not designed to run for as long as it takes to refill tires which can cause it to overheat and likely fail a premature death.

ARB does make high volume compressors but they are more $$$ and few ARB installers install them due to their higher costs.

Second, and nearly as important, is that they are unmercifully slow and would take the proverbial "all day" to refill your tires.

My best advice is to use a different air compressor with the ability to put out enough air volume to allow the tires to be refilled within a reasonable amount of time. I don't care if the compressor's advertising screams it can fill a tire to 200 psi, that means nothing and usually means it puts out such a low air volume (!) which is completely different than pressure, that it will take a long time to refill your tires. More important than air pressure, since even a tiny air compressor can fill a small tire to high pressures, is volume... sufficient air volume is what you need to refill tires within a reasonable amount of time. And pay no attention to a compressor's rated air volume if it only gives that rating when working into 0 psi... since such compressors air volumes fall off dramatically once that 0 psi resistance of the tire starts building up as the tire inflates. A compressor capable of putting out 2 CFM (cubic feet/minute) into 0 psi of pressure may only be able to put out .2 CFM into 10 or 20 PSI.

And pumping out air volume is not what ARB's standard air compressor is good at. It is only good at holding pressure against the locker so it stays locked... which does not require it to put out any volume at all.

Thanks Jerry I appreciate it. I thought i was going to be real slick and be filling up my tires and all of my friends but i guess being generous in this case would of cost me a pretty penny! thanks for saving the wallet

What do think about the ARB On Board Twin Air Compressor?

As Jerry said, if you want to fill tires then it is best to get a compressor which is specifically designed to do so. While not the greatest unit on the planet, if you're on a budget then you ought to pick up one of the SuperFlo MV-50 compressors. It's only $79 at Amazon, and last I knew it was only $59 at Low Range Off Road (and that is a steal for this model).

Like Jerry said, look for a cfm rating at pressure. The MV-50, for example, is rated for 2.54 cfm at pressure, so it does reasonably well at refilling tires. The manufacturer suggests you not use it continuously for more than 40 minutes before stopping to let it cool off, but that will give you plenty of time to air up two full sets of 35" tires from 10 to 35 psi.

The twin ARB compressor mentioned (model CKMTA12) does not have a very small footprint, as stated, and it also doesn't have a small price tag. ARB lists it for $544.

For the record, I just purchased an ARB Air Locker for my Dana44. Since I already have a compressor for airing up tires (the aforementioned MV-50), I bought ARB's small model, the $165 CKSA12. This little guy only puts out .47 cfm at 29 psi, which means it is only appropriate for running a couple of air lockers... but since that's all I'd ever use it for, it was perfect for me.

Yep, that's right: it is cheaper to buy an MV-50 to use for your tires and a separate small ARB compressor to use for your lockers than it is to buy one large ARB compressor to handle both duties. ARB's next-larger compressor (CKMA12) puts out 2.18 cfm at 29 psi, which is less than the MV-50, and it'll set you back $275.

FYI

I bought the high output version (not twin pump). I heard it does decent, I'll know soon enough

Have you tried using the compressor for airing up tires yet? I spoke to ARB USA and they said it was designed to handle airing up tires in addition to running lockers.

How did you plumb the inflation kit? I almost inclined to buy a MV50 for the rare occasions that I need OBA. They are on sale at Amazon for $55 with free shipping. Most of the ranches out here have free air at the gates and even though ARB said it is fine, I hate risking a problem with the lockers.

I am looking for a cheap air compressor to fill the tires. i will take the same route as Sherpa and install the separate ARB compact compressor on the side.

I want to air up my tires from 10 to 27 quickly enough (32s going to 33s soon) can anyone suggest minimum spec numbers?

anyone? i have a portable one which says 15L per minute, which is obviously at 0 psi and its very slow.

i'm mostly interested in output volumes, sth around 30L per minute is enough?

Look at the Viair 400p. No install cost, comes in a nice bag with everything you need to fill your tires from 12 psi to 30 in about 3 minutes a tire, we sell them for about $200, you should be able to find one close so there's no shipping.

There are some good suggestions here. Of course they all vary depending on price, performance, etc. The MV50 is cheaper, but it is not build the way a VIAIR is, and will end up replacing it multiple times before you will need to replace a VIAIR. Now, some guys are Ok with this, but the problem is, when it fails when you go to use it on the trail. That is when it is frustrating.....

OP, what year is your Jeep? VIAIR has the new ADA that is available for 07-11 & 2012 JK's, but also have it in a universal version if you don't have a JK.

VIAIR ADA 07-11 Jeep JK System 40041 - Onboard-Air.com

In most cases, I would recommend the 400C version, since it has the performance and duty cycle to do almost anything you need it to. The great thing about the ADA unit, is it has that small tank for the air lockers, comes with the BSP fittings to install the ARB solenoids, and already has the right PSi switch for the lockers. Also has a quick disconnect on the back for filling tires and comes with the fill hose and tire inflation gun.

There are other options, but this in my opinion, is the easiest solution and has what you need. Give me a call if you have questions or want to go over the other options available. Hope this info helps.

Just did a test, 33" MTZ from 8 to 24 psi in 1 minute 36 seconds, not bad

ARB's middle-sized compressor can indeed air up tires in addition to running lockers. It is a solid, proven unit. Be advised, however, that this model (CKMA12) puts out 2.18 CFM @ 29 psi, which seems to be a bit less than the MV50. Furthermore, its 50% duty cycle recommends only 30 minutes of use before giving it 30 minutes of down time for cooling. Lastly, Amazon's price for the CKMA12 is currently $277.

The faster inflation of the Superflow MV50 combined with its longer use time before requiring cool down and its current Amazon price of $55 makes it a very attractive choice for Jeepers on a budget.

For the price, I don't see how you could go wrong.

Independent testing on 33x12.50-15 tires has shown the following required times for inflating one tire from 10 psi to 35 psi:

Superflow MV50 = 4min 5sec
ARB middle-sized = 5min 39sec

Hopefully this information can help you decide which compressor will suit your needs.

The 400P is also a nice little compressor. Interestingly enough, most of its hardware looks identical to the MV50 (the test above even points this out). The 400P does put out a little more volume than the MV50, however, because in the same test I mentioned above it needed just 3min 17sec to inflate the 33x12.50 from 10 to 35 psi. Not surprisingly, this increased performance comes at a price; for the cost of one 400P you could almost purchase four MV50s and share them with your compressor-less buddies. Each individual must decide if this represents a better value for their needs.

As I mentioned above, the 400P shares much more than a passing similarity to the MV50. At the very least, they certainly seem to use many of the same components. Based on that fact, I don't see how anybody could issue such a harsh judgement against the MV50... but everyone is welcome to their own opinion. The MV50 is very popular among my local wheeling friends, and I've yet to hear anyone complain that theirs has failed.

If anyone out there is worried that an MV50 might conk out on them at an inopportune moment, just buy two of them--you'll still save almost $100 compared to buying the 400P.
