Description

The ARB CKMTA12 twin on-board compressor kits were designed specifically as a compact-sized yet high-volume compressed air source to suit the high-volume airflow needs of most air-powered tools, and also to suit the actuation and control needs of the ARB Air Locker and the harsh and demanding environment of the ARB Air Locker user.

    • Great compressor for 4 wheeling!
Color: Blue and Black

Compressor works great! Not too loud, fills up tires quickly after a day on the trails. Also great peace of mind for road trips combined with having plugs and a repair kit with you. Lots of wiring involved with installation, if you are comfortable with installing stereos/soldering/pulling wires then diy it. It is not for the novice installer and I can imagine a shop would be expensive to have installed. It took me several hours to run all the wires to the fuse box and battery/aux switches. I used a separately sold mount for the cargo area of my jeep which I would recommend if putting into a JL unlimited. The inflation kit sold separately is also a good value in my opinion but not included when you buy the compressor. Overall I'm very pleased with the performance of the ARB twin compressor. It suits my needs for airing up after trails and also I'm able to air up various things when I am not near my home compressor (pool floats, stuff like that). I have electronic lockers so I can't comment on their use for air lockers but as a compressor I've aired up 2 sets of 33 inch tires (8 total tires in one go) and it ran like a champ without hesitation. A+ product, hope it lasts! ... show more

    • GOOD QUALITY, WORKS WELL...
Color: Blue and Black
I'm using this compressor with the "Kraken" 4- Wheel tire inflation system... It mounts under the passenger front seat in my 2024 Jeep Wrangler and is able to inflate all four tires at the same time with equal pressure... The compressor is compact and quite with a continuous deity cycle... It fills all four tires from 20 psi to 35 psi in about 4 minutes... Because all four tires are connected the pressure is equal... I'm very satisfied with this compressor.. ... show more

    • This is a GREAT compressor. Not cheap but well worth the money.
Color: Blue and Black
I don't understand the less than 5 star reviews. This is the best small compressor unit out there; nothing else comes close. It has a fan and a 100% duty cycle. I have mine mounted under the passenger seat of my Jeep and use it primarily to air up tires (with smaller compressor it takes a while to air up a 40" tire!). I also have it tied into my air locker manifold and can operate the lockers also. I recommend plumbing this into separate tank of 1 to 2 gallons. That way when moving from tire to tire it will keep running and build up air in the tank. The compressor shuts off at 150 and starts when the air pressure drops below 130. If you do not need that kind of pressure ARB also sells a 70/100 switch. It is imperative that you wire this properly as it draws a heavy current - each motor has its own 40 Amp fuse. I needed longer wires to mount it where I did and used a few ft of 8 Gauge wire. This is not a kit and is just the bare compressor and wiring. You will need to rig up a discharge line, quick coupler and hose to put it to use. I also like the fact that it is built in Australia and not China. ... show more

Great compressor, fast to fill tires, I can actually inflate the tires faster than my staun deflators can remove the air. I also have mine mounted in the rear of the SUV and have posted a video no youtube to show approx how loud it is in my application. As always your results will vary. But I mounted it to 3/4" particle board (that I still need to carpet), and bolted that to some 1"x1"x1/8" angle steel stock, sandwich clamped to the legs of my Garvin interior rack using grade 8 hardware. I used F4 tape to protect the finish and provide sound/ vibration dampening. I wired it by extending the 10g power wire using 8G wire to the battery. Since there are 2 motors, there are 2 power leadss, so I used 2 8G wire runs fuse with a mini ANL fuse block at the battery with 40A fuses. Youtube video of the sound for reference for those who wish to mount it inside the rig with them. https://www.youtube.com/watch?v=TVDWN7hc_Fk ... show more

    • Found problems that I did not expect on a high end compressor
Color: Blue and Black
This compressor is highly thought of, but I found several issues that I would not expect in a high end product: 1) The housing at the outlet port appears to be made of cast aluminium, and cracked causing a huge air leak. 2) The steel shroud protecting the outlet side of the compressor unnecessarily interferes with the installation of a fitting to the outlet port. 3) The electrical connectors connecting the wire loom to the compressor are difficult to lock. On the positive side, this compressor fits into small spaces, and is pretty easy to install. I am exchanging the compressor for a replacement, and will update this review if necessary after I receive the replacement. UPDATE, FEBRUARY 8, 2018: I have received and installed the replacement compressor. Sexton accepted the faulty compressor back with no hassle whatsoever. Given the good response, I have upgraded my overall rating from 3 to 4 stars, For those thinking about running any sort of air tools from this compressor, you will definitely need an air tank. Don't count on more than a 20% to 40% duty cycle as this compressor can't keep up with any more. This is not a fault, this compressor does everything that it was designed to do. It is fine for inflating tires, air mattresses, etc. I am able to run a pneumatic impact wrench in short bursts to remove lug nuts with the addition of a small (500 ml) air tank. Overall, I would buy this compressor again. ... show more

    • Whoo Betty!

The ARB duel air compressor rocks! Was running a Viair for years. It was reliable but slow for airing up 33’s. Switched to 35’s and the ARB. Can fill all 4 tires from 12 psi to 36 in just under 10 minutes. That’s deploying the hose and putting it away. Less time spent in the rain or snow. Highly recommended. ... show more
