Topic tags/keywords: dust filter homemade heater

I found this old blower fan in an old trash pit we used to have when I was a kid . it was still in the old furnace from our first house and since it was ass up the blower was only covered in leaves and not dirt . it’s been there for 35 years or more in but was still in good shape so I pulled it out the back and hauled it a few hundred yards up to the top of the bluff and took it home and my car. Once I cleaned out all the debris it’s bun freely by hand so I hope it up to a small drill and ran it for a little bit to see if it pulled air. It works great so I cleaned it up a little better and washed it all out with the hose and let it dry . The next day I hooked it up to the old electric motor I had laying around that was for a old furnace I believe and it ran great ! I put a little rust loose near in the lubrication taps just to make sure it didn’t bind up. He five years in that ditch and it still had a good grease on the shafts . After reviewing some peoples projects I decided to make it into a dust filter with filters on both sides of the air intakes of the blower . I’m also seriously considering putting a 220 V dryer heater or 110 V duct heater on the air out take to make it into a heater for my garage as well as a dust filter. I envision wiring it up so that the heater has the temperature limit switch on it to shut it off for safety as well as wiring it so that the heater cannot come on and less I have the fan on as well . What do you think ?

Should work just fine. The filters will clog up quickly so make them easy to change.

I’m trying to make it so that the filters can be slide in from the back sides of the unit and thinking of using a metal screen material behind it to keep it from getting sucked into the motor or fan on either side. I’m going to try and make the slides flush with the outside so it’s pretty seamless and flat all the way around.
