arb air compressor for onboard air RDCKA model

[xjwest]

anyone use this for airing up tires after a run, how much time did it take and was there a problem with the cutoff value switching on that you couldnt finish airing up the tires? thanks!

Mine lasted 5 years doing that, with a tank. It took a L O N G time....only once cutout.

Eventually it ate itself.

how long are we talking?

 

[cal]

It takes me about 10 minutes per tire, taking a 35 from 10 pounds to 30 pounds.

 

[xjwest]

cool, i got 33's so thats not that long, but does it cut out on you at all before all the tires are completely inflated?

Why do you want to use the ARB compressor? Already have one for lockers? For airing up tires, there are much better compressors for the same or less money than ARB.

I was able to do all of mine without it stopping. Keep in mind that if it cuts out it is doing that to try and prevent motor damage....it has already gotten to hot. The thermal cutoff is kinda like an idiot light....it is already to late.

I agree that there are better choices, unless you already have one.

I personally don't think the ARB compressor is up to the task of repeated tire inflation. It's a small compressor, intended to run for short periods of time. Running it straight for 30mins or so, filling four 33X12.5's from 10 psi to 30psi is not what it was designed for; you're asking for trouble. Get a different compressor for airing up.

The documentation with mine said it was 100% duty cycle.

It never has, but I don't use it every time I have to air up - mostly because I am impatient. I wheel with people who have much better onboard air solutions, and will be converting my AC over here shortly.

ohh that sounds cool, how do you convert the a/c?

 

[cal]

There are good writups, I dont have time to find them.

This one gives you the basics

Alot of spobi here,the compressor does not have a thermal overload or a duty cycle.they do recommend not running it over 45 minutes.Ive had mine for 6 years,and it takes about 5-7 minutes to air up my tires,about the same amount of time to hook up my sway bars and dial up my shocks(nobodys ever waiting on ME).You are supposed to keep your motor running while in use so your getting max voltage to it!

Indeed, but it looks like your as guilty as I am. Clearly I misremembered the documentation.

http://www.arbusa.com/air_compressor/specifications.pdf

Model Duty Cycle
CKSA12 35% (21 min on, 39 off)
RDCKA 25% (15 min on, 45 off)
RDCKA24 25% (15 min on, 45 off)
RDCPA 25% (15 min on, 45 off)

Looks like I'm overworking mine a bit. It's lasted this long, it will last until I get my sanden converted.

i would go the electrical route before the A/C setup.
You've already seen mine but heres the link for others.

Mine must have shut off by magic.

In my defense, mine was about 10 years old.

I took my info from my paperwork(6 yrs old) that came with the compressor.I did miss that "duty cycle" on their web site though!

 

[cal]

Yeah, mine came with paperwork that I thought said 100%. It's better when we're both wrong I guess.

cool thanks man!

Yea, I know, I have one as well. I have used mine in a pinch to air up to 20psi before hitting the highway; The motor/compressor gets really hot. There's know provision to cool the motor, and of course no oil to lube it. I thought it was rated at 25% duty cycle. I think letting it run 30+ minutes at a time will significantly shorten its life. I bought a PUMA, which is rated at 100% duty cycle, and gives 3.4CFM at 45psi, as I recall. It has a fan cooled motor, and costs under $200.
