Paint Booth exhaust Fan

I need some advice. I’m looking for an exhaust fan for my build from scratch both. I thought I found a perfect fan that during out to be a “Fan” and not an exhaust fan; meaning the intake is the 4" side and not the flange side (link below). My booth is 30W x 20H x 16D. I know to look for a squirrel cage configuration with the motor/electric out of the paint fume’s path.

Any suggestion/comments would be greatly appreciated before I blow $100.00 dollars on a fan that blows the wrong direction; pun intended.

Thanks - Huey 638

Hi Huey638

Any brushless fan is safe, there’s a lot of ideas around on various designs, here’s mine.

You could always use a 4, 5 or 6 inch fan from ebay if you need ducting.

Thanks Mick;

The entire shop is part of an add on to my house and is a totally dedicate area. I have built the booth out of 1/2 ply and lined the entire booth with lament that was left over from the kitchen cabinet work. I would really like to identify an exhaust fan that can extract fumes from the booth and be vented outside in a 4" dryer vent (already routed). I though this would be simple to find…not so I guess.

There are muffin fans with enough umph to work. And muffin fans are sparkless. You need at least 100 cfm- my current booth uses a 120 cfm muffin fan.

I believe most of the times I have seen this type of fan used, the intake side/hole was affixed to a “connector/seal” made out of metal, wood or foam to bridge and seal the gap between the cabinet and the fans input hole.

This would assist in keeping the fan in a straight orientation to the cabinet. Then, the output flange would be attached to the duct work.

Your cabinet sounds like a winner, already
