Hi,

I have a grizzly 2 hp 220 DC . It seams to have pretty good suction (rated 1700cfm). But when the filter gets clogged it slows down.

My unit is in a shed next to my shop so I was thinking of removing the filter and make a plywood cookie with a 6” pipe to the outside of the shed where it would end up in a box of some sort. I hopping to get a little more cfms and stop having to spin the filter cleaner.

any thoughts?

This is usually done with cyclone so that only the fines are blown to the wind. But it will work with a single stage as well, you just may have a little more debris outside than you though. Consider a few things: if you shop has conditioned air, it will be blown outside as well. It will increase your CFM’s, maybe to the point of motor overload. Best to check the amp draw and compare it to the motor plate. Oh, I doubt the box of some sort will have much in it, but you can try.

The only reason for the bag or filter is to retain the sawdust and finer stuff so it is not re-blown around your shop. If you have a place to blow it to that doesn’t matter if the fines are airborne and the larger dust is in an acceptable place you should be okay with just blowing it through the wall to where ever. As long as your not causing a negative pressure in your shop which can have bad side effects with gas heaters and such, and you don’t mind blowing cooled or heated air out of your shop I’d say go for it. If I lived in a rural area I’d blow my dust outside.

I have the same unit. I built a thien baffle and vented directly outside with nothing to catch dust on the exterior. I have yet to see any visible dust outside. In my opinion, this is definitely the way to go. You can check out a larger photo on my workshop page.
