Just finished my air filter for the basement shop!

The project started with a gift from dad’s best friend who is in the HVAC business. It is a 220V blower out of a carrier unit. I had to disassemble and clean it as it was from a unit installed in 2005.

The wiring was a little tricky as the unit is a two speed and 220V. I really wanted a timer but couldn’t find what I needed at Home Depot. I ended up installing 1 switch for on/off and a 3-way switch for the high and low function.

I can draw up a wiring diagram if anyone is interested in doing something like this.

For filters right now I have a washable pre-filter and a Honeywell FPR 10 pleated filter. After cleaning up the shop one time the pre-filter barely has any evidence of dust but the Honeywell looks like it is ready to be changed. I will be investigating other options for this.

Thanks to all those on this site for giving me the idea.

I like it. I need to build one myself.
Thanks for sharing it with us.
