DIY dust cyclone for my workshop

I had a dust collector with a dust bag.
The dust bag gave away more fine dust than it trapped, so I figured I needed something better and build myself a cyclone.
I bought:
- a 2hp fan
- a hepa-filter
- a 7mm sheet of sheet metal
And I had some scrap wood as well as a old garbage dumpstrr from my parents.

I shaped the cyclone, buildt lid and stand from wood and connected it all.
The cyclone was painted with hammer-paint.

The result was greit. Good suction and there is almost no dust at all that gets through the cyclone and into the hepa filter!

I’m very happy with the result!

Yeah… I havent worked mutch with metal before, so it was a fun and interesting experience to try to make something out of sheet metal.
And it’s really working great. I can fill the whole bucked with fine dust from the table saw and shavings from a planer and the bag below the hepa filter will still be empty.

I have also installed duct work as well as DIY blast-gateways.

This is a GREAT solution. I have a question about your last picture where you are replying to Maniac Mike/ What is the metal strap you are using to fasten it to the wall called?
Thanks.

Sorry, I do not know the english name. In Norway it is called «patentbånd» and you can get it in any builders shop.
Her for example: https://www.biltema.no/bygg/byggbeslag/hullband/patentband-galvanisert-2000032281

I tried to find the english translation, but had no luck. The closes was «steelband», but a google search for that did not give the expected result.

Maybe someone native know the right word. Here it is used «all the time» in building construction.

Edit: it may seems like «steel hanger strap» gives quite many hit, so that might be it.

It’s just called steel strapping or perforated strapping. You can usually find it in the plumbing section of your local big box or hardware store.

Great set up!
Really well build.
Inspirational.
If I get some more shop space, I will make something lika that.
Det er kempe flot! (Siger man sådan? Jeg har Norsk familie i København, Stavanger og oppe ved Rjukan).
Best thoughts,

Laughing high.
Ja det er bare mit forsøg på at få det til at lyde Norsk.
Min elskede onkel siger altid Kjempeflott, så det burde jeg ha kunnet.
Bedste tanker,

Sweet roll your own cyclone, and if it works as advertised I tip my hat to you.

I frequently see the join of plywood, and some form of fitting through from the cyclone, which you also clearly showed. What I keep missing is how are you connecting the square/rectangular offshoot from the vac motor itself, to the filter. Nobody shows what they do there.

On yours it looks like you used a small dust hood, and then some sort of sheet metal elbow to make the connection??

Any pics of the build of the join there?

Probably not the exact same product, but it can be used the same. Carried at all of the BORGS, this link just happened to be Home Cheapo.

The transition from square to round was included with the fan, as you can see on this picture of the fan:

Then I used a flexi hose from the outlet of the fan and into the hepa-filter.

Thanks. Mine has a rectangular box, and it matches a machined fit the same. Except to use it I feel like I have to turn it at a right angle from how they have it working. Turned to a right angle the parts are off, just trying to work through how I’ll attach to filter.

Maybe you could post a picture explaining what you mean?
It’s a bit hard for me to understand just from the description.
