Nothing too special here. I don’t post very often but I check out this site everyday. I built a shop-vac cyclone a couple years back and I absolutely love it. In two years I think I’ve shaken out my filter once. Anyway I’ve had a little HF portable dust collector sitting in the corner for a year (1hp I think) and I finally said to myself “why don’t I build a cyclone for it. I’ve seen quite a few cyclone and thien separator build lately but I decided to mount the dc right to the top of the cyclone. It works great and saves space. I don’t really have much to add. The build was straightforward, used 2 piece of ductwork gauge shett metal with pop-rivets on the seams. Foil tape over the top of that. The only thing which I don’t care for is that I wish the dc was a 2hp. I won’t be able to have 2 blast gates open at once (once I put in my duct work). The whole project was scrap plywood and sheet metal. The cost was $12 for the metal and I think I paid $90 for the dc last year.

That is a simple solution. Great work.
Do you vent outside or is there a filter that I am not seeing.
I would have guessed that ductwork metal would collapse under the vacuum of the DC.

Had I seen this before I built mine I might have copied your design.

Thanks for sharing.

It vents directly to the outside. The guy I bought the house from had a garage heater hanging from the ceiling in that spot so the vent was already there. The garage is at the rear of my property so I’m not worried about any of the fine dust shooting out there. This is my third cyclone build. 1 for a shop vac and 2 for dust collectors. The sheet metal is just duct work guage from the local big box. When you bend it to that tight a radius it becomes very stiff. I believe it would take way more than a 1,2 hp or higher dc to collapse it.

Have your say...
