24v air compressor

[Glenn-BJ74]

There are 24 v surplus air compressors available from a US supplier if anyone interested. There are for Hummer central tire inflation systems (CTIS) available at $80 US. I installed one in my last vehicle - very strong industrial unit - 100% duty cycle. I have an 24 v ARB compressor now and its not as strong as this one.

Thanks for the heads up. Any suggestions on where to install it on a BJ74? From the dimentions they list it looks a little big, not to mention heavy. 26 lbs? I would say that's a pretty heavy duty unit.

I don't doubt they are tough. But the specs seem wimpy.

50 psi is too low. And 1.3 cfm is not a lot. Can 50 psi even work an ARB locker?

Also 12 amps draw is significant.

I dunno. I just got a killer deal on a 12 volt Viair 280 and paid $300. It draws 30 A and produces 2 cfm at 100psi. Its a bit smaller and makes 200psi.

50 PSI will run arbs and fill tires. None of them really run air tools reliably except the super large Extreme air units. $80 is too cheap to pass up. I think I'll buy one of these and decide which one to keep when it gets here.

80 is pretty cheap. Your Viair sounds like it can run an impact gun. For short bursts.


I have a slow compressor in my garage. When the pressure hits 50(decreasing) tools become almost unusable.

90 plus psi is good for tools. But I know these compressors for use in vehicles are for filling tires and locker engagement.


I went the York route. I bought a used 9-10 cfm york. Made brackets and mounted it up. At idle it pumps a lot of air.

I have a pressure switch to control the on/off. At 90 anb 120 psi. I have a small 3 gallon skinny tank for mounting on the frame rail.

Bruce,
I have that Viar, don't know if it is the same model, but it is the smallest 100% duty I think. It pumps pretty good, with a tank it would be real good.
Cheers,

These units are surplus compressors from the US military H1s. They are way underrated as most military specs are and are much stronger than the 24 volt ARB compressor I have.

As for placement - put anywhere where you would put an ARB compressor. No room under the hood so I put my compressor in the jack area - rear left corner. at $80 they are a steal. To run ARB lockers need to connect to storage tank, with pressure cut-off switch., with all the plumbing, etc.

 

[maximBJ70]

how big are these things, the dimensions seem really big (twice the size of ARB), are they accurate?

EDIT: just got mine..YUP they're BIG

I am unclear if these things will run tools, impact ect. I want to make custome bumpers and sliders and am thinking of making some/all a tank for my compressor. I don't know jack all about this though. Will this work? what else would I need for valves/ plumbing ect? I would love to be able to have a decent compressor onboard that could comfortably run some tools and stuff. any help much appreciated, thanks

The volume is barely ok for air tools but the max PSI isn't. 60 psi is too low for most aitr tools. Nearly no electric really has the jam for air tools. The exception is the ones that are effectively a winch motor connected to a York compressor. Adding a tank helps a lot. You can run the tank down, say loosening the six lugnuts on a wheel and then let the tank charge while you are swaping the tire. There is no hope of running a die grinder or sander or cutoff wheel without taking two minute breaks after 30 seconds of work.
