Topic tags/keywords: exhaust fan workshop dust question tip

I am finishing my new (800 sq ft!!) woodworking shop. While I’ve got the ceiling joists still open I thought I might install one or two exhaust fans to help get rid of dust and odors. I know I need something stronger than a regular bathroom type fan. What size exhaust fan do I need? Has anyone read an article on this, or maybe figured it out on their own.

I use an air handler unit from a hot air furnace. It is the squirrel cage type with either a 1/4 or 1/3 horse 110v motor. I have it mounted in the window to exhaust to the outside.
