Educate me on spray booths

[LDO]

Is the fan on only when spraying? It seems like a fan would just draw dust in if left on. Shouldn't they have doors to keep dust out after spraying is done? (I'm guessing yes, but $$$ prevents most from being cabinets).

I'm curious because I saw a cool article on building one with a squirrel-cage fan from a furnace. I can get those free at work (used, of course) and I have a ton of scrap lumber/plywood.

Yeah, you use the fan to draw fumes and overspray out while painting. No sense to run the fan once you're done painting, IMO.

My Pace Peacemaker draws all paint overspray, AND fumes OUT of the model room (solid particulates captured by the filter, fumes go outdoors), but it does not pull so much air as to bring lint or dust to the painted surface. Living in an apartment in a house with Central HVAC, I feel a real need to make sure that no smells spread into the HVAC, so I leave the blower on the booth run for at least 30 minutes after I am done painting. Gives real meaning to the name "Peacemaker" IMHO!

Art, does it use a carbon filter ?

[Harry P.]

It uses whatever filter you want to put in it... assuming you can find the right filter size. Pace sells replacement filters, but they're nothing special, just regular old pleated paper filters like you can find in any home center.
