This is the reason I love this site. I bought a Harbor Freight 2hp Dust Collector. The first time I used it and sucked up something somewhat big and heard it hit the fins I stopped using it. Then I was browsing the Projects and came across something like this that HankLP made. So I used his design and made a couple of changes. It works PERFECT and I don’t have any vacuum leaks. And it sucks up some really big chunks as you can see in the Pic.

Excellent improvement. I made a similar separator, and it put a stop to hearing bits and pieces hitting the impeller blades. It also means that any items that are sucked in by accident can be retrieved undamaged, and your filters will also stay cleaner for much longer.
Good choice.

I have been trying to decide if I should do something simple like this to mine, or go for a full Thein Baffle. This seems so easy and cheap:) I am installing a new MERV15 filter next week and I don’t want it clogging super fast. Would you say you have lost any suction with this separator? If not, I think I should do it ASAP.

Thanks Druid. And kocgolf I don’t believe I lost any suction. You see the chunks inside. I picked those up using 20’ of 4” hose. It was runing on the ground and it picked them up off the ground and through them in the bucket. So in my opinion it was WELL WORTH the upgrade. I had about $80 into it. I got all the stuff at Lowes. I think the reason I don’t lose suction is because I put a double gasket around the rim and RTV to seal the other holes. And I can guarantee I will not have anything larger than the mesh I used.

I went with the Veritas Cyclone lid for $50 and a rubber garbage can with some internal baffles, works like a charm.
Also replaced most of my flex hoses with 4” rigid PVC pipe and actually gained suction! Thought about putting a gasket on the lid but hard to remove when system is running so haven’t bothered?

I am just starting to research dust collection and large chunks (as in bigger than shavings) is what I’ve wondered about passing through fan blades. Inventive! And timely. Thank you.
