getting off the topic of mounting slightly, but considering everyone here apparently has arb compressors? has anybody ever considered making them multi stage???

Ok how would we make them multi stage?

compressed air coming out of one compressor into the intake on the second? would this increase efficiency of the pumps provided you could cool the air between stages??

Hi Goose man...

That could be an Goose of an idea but I guess it could also work.
But then why would you want to?

My ARB Compressor seems to run at a much higher speed than the earlier types and will pump all 4 Tires from 20 to 50psi in about half the time as the older compressors - ok maybe not half but it is quicker.
I have been looking at fitting a storage tank with the idea of having high volume air available, anyone tried this on a 4x4 is it worth the effort?
I am currently looking at using an old 15kg Gas Bottle, previously used for R22 Refrigerant Gas.

been toying with the idea.

i have seen a dual stage 12v electric for sale. not big flow but will has a 175psi cutoff and 100% duty cycle.

the point of doing dual stage is they are more efficient and can do higher pressures than a single. the trouble is its a trade off, they don't flow as well at low pressures. your restricted by the flow of the smaller compressor.

most oil less compressors i guess you could feed output from one big one into a smaller compressor. as long as the shaft seal doesn't leak.
not sure about using two identical compressors. the one the intake side would probably rev its guts out trying to supply the other. you need a bigger compressor (ie more suited to flow rather than pressure).
if you got 3 cheap compressors, run two in parallel and have them feed the third. could even get fancy and bypass the third one when the pressures are low.

edit: why do it? mainly so you can pump a tank up to higher pressures eg 200psi. or do 100psi easier or with budget compressors that don't handle 100psi very well. eg two pumps do 50 psi each but you get 100psi overall.
