Hi,
I built a dust collector with a thien baffle a few years ago, using a 3 hp blower with a 160 mm hoses and pipes.
Until now, the blower blows the air outdoors. This has worked well, but cools the workshop down quite a lot in the winter.
I am moving this summer, and will have neighbors too close to just let it blow outdoors in my new workshop (because of the noise - it sounds like a jet engine). So, I'm looking at adding some filters to let the air back into the workshop.
My first thought was to make two rectangular drawers, one with a coarse filter, and one with a hepa filter. This feels like a great setup, as I can just pull out the drawers and clean them outdoors. However, I've started wondering if these filters will let enough air through. Maybe this would remove too much suction power from the dust collector.
Would a hepa cartridge filter be better? Like this one:

That one seems to be designed for a 2 hp blower. Maybe it would be too small for my 3 hp blower?
I'm attaching a drawing of the version with two filter drawers. It's a see-through version, so the walls around the output are not visible.
