I have an edwards E2M30 with an EMF20 oil mist filter. I want to attach some tubing from the outlet on the mist filter and run it into the exhaust via a a kf25 to large house barb adapter. Does anyone do this? I just wonder if this would create issues with back pressure?

Yes I do this nearly everywhere I go. You can buy the parts on idealvac.com. it’s best to plumb it into some sort of active exhaust fan/ducting. I’d keep it at it’s exhaust diameter all the way from the pump to the active exhaust housing. You can even just port it into the side of a carbon scrubber and it makes a world of difference in the room

Awesome thank you! Do you have any advice on the easiest way to match the diameter of the KF25 outlet? I use KF25 bellows hose to connect the pump to cold trap, but that stuff is pretty expensive and I need to run it about 15-20 ft to the exhaust duct.
EDIT: I see ideal vacs has kf25 flanged pvc hose that’s not too bad price wise.

You wont have any issues or noticeable loss of vac, even without an active exhaust (but that’s a good idea to help sweep things along).
They make kf25 to barb, and you can use any hose or ducting you want. Just be aware of explosive/flammable solvents pooling.
