Here's my exhaust fan which has a sealed motor, and sealed switch. You can see the last paint job was red! LOL It's from Grainger Supply. If I was building a new shop it would be explosion proof.

Here's my exhaust hood I installed to keep the neighbors happy. I have taped a sheet to the siding, and wet the ground to catch the exhaust fumes.

This gets me by since I do mainly my own projects.
