12 Volt Air Compressor

[ZooMad75]

Hey Rob, what size wire/cable feed the bus bar? Which kind of resettable circuit breaker.

I do not want to go the battery. My plan was to go to my VSR, voltage sensing relay, aux batt side, 4g feed, protected by 175 amp manual reset circuit beaker

It was 6 ga from the battery to the circuit breaker which was an 80 amp unit from Amazon. Then 6 ga to the bus bar. Which I’m using the bus bar from gmt400 trucks that they had up on the firewall.

My guess is the Chineseium circuit breaker might have more resistance than say a higher quality unit from blue sea or other known brand.

Personally I just didn’t want another throw away compressor. I had the $50 cheapy everybody picked up when checker had them on sale. It failed eventually, besides being slow. The smitty failed after a decent lifespan. But it still quit working. I took it apart and besides the cheesy wiring for a relay and thermal cut out switch it just screamed low quality.


I’ll have to find it. Somewhere recently on the web there was a comparison of all the recent 12v compressors. I can’t remember where I saw it. I’ll look tonight.

Did you figure out what died on it? I'm curious if it's the oil-less aspect that ultimately causes these to fail, or just/other poor build quality like bad soldering, cheap components, etc.

I'd take a look at the review if you find it for sure. Many of the reviews and articles I see on these things really just look like advertisements.

I don't want a York, but for the price of the ARB stuff...

I have an ARB single but I use a CO2 tank. Airs up my 37s and @Fastereddie uses one for 40's

And I also have a Viair for backup.

I think it was electrical in the failure. I did take it apart earlier this summer. It seemed like the piston moved freely in the bore. The reed valves in the head were not damaged either.

They do have a built in thermal limit switch and the switch on the side feeds goes to a relay. Any one of those could have failed or the motor could have taken a crap. I didn’t take a deep dive with a meter to pin it out though.

If the weather prevents me from working on the blazer this weekend I might look at that side.

I've had this for a few years works great a little bulky and heavy but fills 35's no problem durable too it gets knocked around quite a bit. Prices have gone way up I paid less than $200 I see them now for over $300.
