As in every other shop in the world, dust is an issue in mine. I have a few wood species allergies so I’m all about keeping the air clean. In conjunction with wearing a respirator, I made the AFS to keep the air clean and keep dust off my coffee cup lid. I live in the Atlanta area and even used the squirrel cage blowers are ridiculously expensive so I delayed this project indefinitely until I could find a blower I wanted to pay for…. Several months past and I go visit my Aunt who had a 3/4hp blower in her backyard. So me being her favorite nephew and all she donated it to me. Fast forward a couple weeks and this beast was awakened. I work out of a one car garage so this unit is a complete overkill, but I’m of the mindset that overkill is underrated. On the maiden voyage I literally blew every bit of dust I could find into the air until I could barely see the back wall. Literally 2 minutes later the air was so crystal clear. I’ll chalk this one up in the win column. Wired for 3 speeds but I usually leave it on low while I’m working but crank it up to high at the end of the day to leave everything relatively dust free.

Thanks for looking

Very nice! A friend has donated a double barrel blower (220) and I’m about to build one for my shop. Love the idea of three speeds (sometimes the simplest idea can be the brain fart of the year for me). My only question is why you put the inlet filters and opening on the back instead of on the side of the blower.

Great work!

I live in the Atlanta area too, and every single day I ask myself why everything is so expensive here, and why selection is so terrible. I feel your pain.

I have a squirrel cage and filter set up on my ceiling. I only have my filter on the side of the blower. I keep on burning up the motors. I am now using a two speed blower. Is there something that I am doing wrong, or does anyone have any other ideas other than buying a regular filter system for the ceiling?
