$10 Harbor Freight Catch Can

[Foobar]

Good job. I also recommend adding some copper or stainless steel wool in there to give the oil vapor some surface area to condense on to.

I'm interested to see how you mounted it. The first image doesn't seem to be working.

Its really not mounted to anything. The hose is stiff enough that the can just kinda leans on the support bar

What exactly is that thing marketed as? There's no Harbor freight in Canada, The next best thing is Princess Auto, but I'd need to know what I'm asking for if I go looking for it.

The four screw holes at the top of would be perfect for mounting two cushioned clamps.

Looks like a air\oil separator from compressor section

why did you remove the filter?

Great job for a cheap alternative oil catch can I'll definitely look into it and do it soon
Also I think its great for it to be clear so you'll know when you need to drain.
Thanks for posting

It's a mini air line filter used in conjunction with air tools. It removes moisture and particulates from the air being pumped.

The filter media probably restricts quite a bit. Not sure that would be good for an air/oil separater or catch can use case. Would probably get clogged up with oil pretty easily as well. Typically you would want some loose material with a lot of surface area for the vapor to condense on to, and something that wont deteriorate or rust, since you don't want any of that crap going back into your engine.

ML, from a safety perspective, it would be worth investigating if you could safety wire the bottom fitting of the catch can to the top mount. This would keep it from twisting off the boss fitting. I would also run the safety wire through some clear tubing from top to bottom so the wire doesn't cut through the plastic oil trap.

I'm having a hard time picturing, or understanding what you mean.

I hold a aircraft repairmen's certificate and I've done a little bit of motorcycle racing, so I'm a little obsessive about these things.

So the bottom part (plastic) of that air/oil separator just twists off. There is a possibility that the bottom could inadvertently twist off due to vibration. I would secure the plastic bottom to the metal top. Since there isn't a hole in the plastic body to insert twisted safety wire, you will need to attach something to the bottom drain fitting where you can pass safety wire. To keep the safety wire from damaging the plastic housing, I would encase the wire (that now runs from the top to the bottom) in plastic clear plastic tubing. I suggest clear so you can always inspect the condition of the safety wire.

Possibly use their larger unit

Ok, I understand. I wasn't concerned about the collection container coming off mainly because there is a o-ring between it and the metal body, so it stays tight. But that is a good point if you think its something to be concerned with.
