no idea if that one is a good fit for you or not, just first one I found on ebay
search for a refrigeration oil separator
you'd nee some way to drain the oil... on industrial refrigeration there's a little solenoid worked by a float switch or a timer - solenoid opens and oil (from high pressure side) is blown back into compressor input (low pressure)
you could add a drain tap and do it manually ? - the separator needs to stand up on end, but you can put a bit of pipe on for the drain and then put the valve wherever you want it - as long as you have air pressure when you open the drain the oil will be pushed out by the air ?
or... if you have space under it, you could have a little glass bowl fixed right under the separator, which would show any collected oil and let you know it needs emptying ?
alternators are in a bad place if you like to get wet and muddy that will be moved soon tooair on an l200, aircon pump as mentoned, i used to have a 3hp belt drive pump with a hevey duity 12v motor of a bust 12v hydralic power pack, but it had a habbit of destroying alternators and batterys so gave up on it
That looks like a good idea, much better and the oil could probably be re-used, I am right in thinking the pipes are brazed or soldered to the out puts on this and the smaller one is for the oil drain.
How often would the oil need draining, I guess that is a how long is a piece of string question.
I could fit a float switch or timming too but then it starts getting messier.
yes those are brazed on - you could braze some short bits of pipe into them to fix flexy to, or something like that ?
I think the drain pipe is threaded, should hold quote a bit of oil too
I should have mentioned, they're good for massive pressure, on a hot day my freezers at work see 400psi or more
I think.... they're just a tube with lots of stuff just like wire wool inside... incoming air blows through the wire wool which should catch any oil mist/drops and let them drip down to the bottom where you drain them out
if you made your own, you could add a tiny pin hole (or valve made for it) for the oil exit and have that joined to the air in of the compressor... then any oil in the air should be caught and added back to the compressor input ?
you'll lose some air pressure/flow... but if it's just intermittent use blowing up tyres etc.. a bit of airflow loss doesn't really matter ? you should have way more airflow than you need anyway ? - advantage of this way is it's hands/maintenence free ?
sounds a bit like the catch can I modified then! I have ordered it now, I think they might have a little float in them too. for £20 it aint too bad I thought. I cant wait to have a play around with it now. I think the 19kg gas bottle might be a bit heavy to mount to the chassis though!

how much air do you need????? ............(off to read the full thread again to see if you said what you were using it for)
Look for a wagon air tank mate, they come in loads of different sizes and you can get aluminium ones too!ha ha it is too big mate I need something half that size and weight! I will be able to use some air tools if the need orrises when off road as well as inflating tyres and air horn
what did you use for a tank in the end?Well the tank is mounted just waiting on the compressor bracket.
shall I use copper, speed fit or proper nylon air line clipped to the chassis to feed the tank in the rear from the compressor at the front?
