I do not have 3 phase and the blower is from an older furnace with the belt drive setup. The motor is actually from something older that I had laying around so it definitely has a start capacitor, etc.
I think with the blower pushing air into a plenum that has a 90 degree turn to the exit and a lot more exit area than the intake side of the blower the exit velocity into the booth should be pretty low. I also plan to have filters on the plenum discharge to help even out the distribution. There is a fair amount of air moved by the blower but the disharge area is only about 18" x 6" sow if I have a plenum with 4 24x25 filters the veleocity should be pretty low in the room.
I considered just having a static room but I have the blower on hand it seemed like a good idea to use it.
It will take some time to build but I need warmer temperatures before I can paint so it may work out.
I am planning to paint parts, or at least areas of parts seperately then paint the whole truck once it is assembled. I choose a non-mettalic paint with hopes that it would work better for this approach.
