Hey all, I’m working on getting the 2HP HF dust collector and then a Wynn filter to put on it. The question I have is in regard to cleaning the air as well. I was thinking of putting a piece of Drainage PVC that has holes along the bottom of it (or something in that manner) along the ceiling of the shop with a blast gate attached. then I can run the dust collector and possibly have it clean the air as well. Thoughts on doing this….

Thanks Everyone

Four comments.
1) that’s a ~2 hp motor, the exact number is irrelevant, it will suck about 12 times more energy than a typical shop air filter.
2) most shop air filters have a sound level around 60 DBA or less, not enough to make you have to raise your voice in a normal conversation; the dust collector, though quieter than a shop vacuum, is still pretty loud..
3) I doubt the motor and bearings in a dust collector designed for intermittent use will hold up very long if subjected to long term continuous operation.
4) I have a HF 2HP DC and I like it and it does a good job of collecting dust from my miter saw, table saw, jointer, planer, lathe, sander, and band saw. I would hate to listen to that thing droning on while I am trying to work when other power tools are not running along with it..

You can do that. I have a 3hp dust collector outside my shop and
when I make a mess in the air blowing dust with compressed
air, I fire up the exterior unit, put the hose in the shop, roll the
door most of the way closed and walk away. It sucks the airborne
dust out of the shop pretty quick.

I’ll concur though that dust collectors are noisier than air
filters. I have both. The big dust collector is way faster
at cleaning the air in the shop, but of course the bags
are outside.

I don’t think the dust collector will clean your shop air
effectively through little drainage holes, but a blast gate
with one open end will.

Have your say...
