Filters to use with EDC

What do you guys use to remove the oil from the air on an york edc? I run a coalescing filter but those damn things are expensive from kilby and they have went up 50%. Have you tried just regular water traps like smc or similar? Mine is a pain in the ass, It has a automatic drain on it and when it is draining I can't fill up the tanks and with the edc running it won't shut off either. This one is I got off ebay a few years ago and want to get a new one but don't want to dump 120$$ on one. Cuz I am a cheepmofo

I used a water trap/filter w/a drain on the bottom, just had to drain it like once a week. I don't know as though it did a great job of getting the oil out. I picked it up at industrial pnuematics place locally, I don't remember what I payed for it, sorry.

Anyone else?

cant remember but i will check today at work and see whats all hooked up at the shop...
