EDIT This post has been up for over a year now and has just become somewhat popular again. I have had the outdoor exhaust with no problems since then. I do have a chip separator (that actually collects most visible dust as well) before the impeller. I have not seen appreciable dust outside my house, much less any “pile” of dust. I am a hobbyist and do not use my DC for long periods of time. You’re situation may be different. I do not inhale CO from my furnace or blow dust on my neighbors. You’re situation may be different.
I think this could be a good discussion. Who cares about spending $2K on a dust collector if you can collect chips inside and blow all that less than 30uM dust outside? Speaking as an amateur and not a commercial shop. i.e. limited hours per week with the collector on. I made a three-gang blast gate box today and was messing around with my Jet DC1100 when I thought of removing it from the mobile base and mounting it to the wall/floor. It’s tucked away in a corner anyway. Then I started thinking about upgrading the crappy 30uM bags with some low micron canister filters. I have the 19.75” Jet so the Wynn filters still need retrofitting. Then I started thinking…why not just vent the whole thing outside. I have a chip separator so only dust goes in the bag. I have a low-level deck on the back of the house and I guess I would just vent under the deck. Has anyone done this? Then I can mount the motor on the wall and skip the bags. It wouldn’t be too loud with the motor inside, everyone’s got more than an acre around me. Also, the small amount of time I use it wouldn’t affect the negative air pressure much. I guess I could crack a window. So any advice or experience with this topic would be great. Seems to me like a fairly quick and beneficial solution.
