So, I am in the process of setting up shop again, after moving.
I want to build a dust collection system. In the new house, we had to replace the furnace, and instead of throwing it away, I kept the blower from the old system.
Would this work as a blower for a dust collection system with a cyclone dust separator?
Provided of course, a proper shroud for the suction.

+1 for the air filtration system, make the box and the air filter could be a premium furnace filter to your size.

Been there done that….only kinda worked….but not worth it as a DC….maybe as an air filtration system. It won’t build enough suction to pull sawdust away from a tablesaw, jointer, or planer to keep the hose or duct from plugging.

+1 No. Not enough suction pressure to be useful for dust collection.

If you decided to use the blower for shop air filter, make sure to check motor voltage on name plate. Majority of Heating + AC system blowers use 220/240V rated motor. Typically want a blower from a gas furnace only unit if you want a 120V rated motor. Nothing wrong with making a 240v air filter, as long as you have an extra 2 pole circuit for it.

OK, thanks for the answers !
Not really what I wanted to hear , but at least it will save me the time I would have spent building a shroud for it, and setting the whole thing up…

If you think about it all the saw dust and wood chips will get pulled throught the motor and plus the design of the squirrel cage fan cannot pass the heavy wood particles. Dust collectors use fan blades just like leaf vacuums and the motors are isolated from the air flow.

Well, as already mentioned, I will follow the advice given by the previous posters, and not go ahead with it..
However, since I would have bee using this thing behind a cyclone, wood chips and dust being pulled through the blower/motor wouldn’t be that much of an issue

Yeah… you just keep thinking that. The cyclone doesn’t remove the fine particles and the blower motor you have is designed to run behind an air filter. The dust getting through the cyclone would clog up the motor after time causing it to overheat and eventually killing the motor. Plus I doubt that blower has enough pull to operate a cyclone properly.

Killing the motor is not the big problem. The possible fire caused by an overheated motor in the wrong environment is the biggie. It is an open frame motor designed for use in a filtered, clean airstream.

+3.

They’re good for moving filtered air in a plenum. They are not high-volume air movers.

Probably not. You need a few HP to collect dust.
