After I wrote about using a furnace fan, I went & looked at my filter unit and maybe there’s no way to get the motor shielded, since it sits in the middle of the fan. I have seen these squirrel cage fans that don’t surround the motor and are operated by a v-belt. Maybe one of those could be adapted to an extended motor shaft that runs through a grommeted hole in a motor enclosure box. Another thing about exhausting a spray booth, is to draw the air through a fairly porous (cheap) furnace filter, or maybe 2 successive filters to get most of the air born material out before you run it through the ducts and past the fan. These will fill up fast, so the pricey filters with the really small pores will plug too fast. The filter should be right at the booth/exit duct interface so the ducts stay as clean as possible. We used special auto spray booth filters. Maybe an auto paint supplier has them.-SST
