DIY 3hp Automatic Dust Collection System

This is my 3hp dust collection system. I am trying to make the most efficient use of my limited space (21’x21’ 2-car garage) and have designed this system so that it takes up zero floor space. While it is not a traditional cyclone collector, it does have a very functional separator which, so far, has worked perfectly. I also incorporated recessed magnetic sensors into the blast gates so that opening any of the gates turns on the DC.

Looks good, up and out of the way. I have mico-switches on my gates, how does the magnetic sensors wook?

WOW thats awesome!! You got any plans or more pics of this? I have a garage workshop too and this would be great to put in mine so I can have more space.

Looks great! What kind of blower/fan device are you using?

jaykaypur: Thanks! It took me forever to research, design & piece it all together, but it’s definitely worth it. The best part is the cost. The entire system (including 6” pvc ductwork) probably only cost around $1000.

bugz: The mag sensors work exactly the same way, except they’re cleaner looking and pretty much fail safe. Just make sure you get “normally open” sensors, because typical house alarm sensors are “normally closed”.

DaddyT: Thanks! I have tons of pictures. I’ll post some more.

“Looks great! What kind of blower/fan device are you using?”

The motor is off a Jet DC. I found it on CL for $100! I then ordered the 14” steel fan from Jet. The blower housing (as well as the dust bin) was salvaged from an old 3 phase DC I also got off CL.

Thanks for the positive comments everyone! With everything pushed to the front and sides, I can still (barely) fit two cars in there…although I rarely do :)

I love the zero floor space idea. Good thinking.

Yet I am still not sure of the design itself. From the top most picture I assume the the square white box closest to the ceilling is the blower assembly. The middle square white box is the separator and the bottom most circular bucket is the actual dust bucket.

In some pics the middle assembly has your intake pipe but on other that pipe is not there;
On the pics you added afterward for example it looks like it is showin the middle assembly but it does not have the input pipe and it looks like you have a conical separator.
On the picute immediatly below where we can see the input pipe, the conical separator is gone and it looks like a Thien separator instead of a conical cyclone. plus the colours (yes I am Canadian) is different Blue for the conical and brown for the Thien.

Am I missing something, it looks like the pics come from two different versions?

If it all works, you’ve definitely beaten the dust collecting system found heretofore. I like the small footprint and the blast gate sensors. Thanks for sharing.

Snowfrog: Sorry, the pictures are not in chronological order. I took them as I was building it, but didn’t post them in order. The conical sheetmetal piece is the intake for the blower. I made it conical to try and get higher separator efficiency. I figured the reduced volume towards the bottom would speed up the air like a cyclone does in order to shed the finer dust. The mdf plate underneath that (with the slots) is a modified Thien baffle like you thought. Does that answer your questions?

Skylark: so far it has worked flawlessly. I took down the filter after the bin was 1/4 full and there was nothing there. The bin is now about 3/4 full, so I will check the filter this weekend to see if there has been any blow-by/scavenging.

Thanks guys!

That’s real nice! I wish I had some over head space to do something like that! Nice work !!!
