Santa Claus left something special for me under the tree this year... well, it didn't quite fit under the tree but you know what I mean. It is a Paasche HSSB 2216 spray paint booth and something that I should have had for quite some time. The idea is simple... there is a hood as seen with a large exhaust fan in back. There is a series of filters that the exhausted air passes through to remove most of the paint particulate; the remainder is vented to the outside of the house through a normal clothes dryer-type vent. I should have had one of these a long time ago; they effectively remove most of the paint and harmful vapors associated with the air brush OR the rattle cans.
The unit is big... much bigger than you think because of the fan & exhaust vent on back. It comes partially assembled and only took about 15 minutes to finish assembling. Venting to the outside of the house will be another issue though. There is an old window in the basement that opens out under the porch that I'll remove and replace with a more solid, air-tight piece of plywood. I'll be able to put the outside vent in that then simply connect the two with flexible dryer vent hose.
If I remember correctly, the unit is rated at moving something like 110 cubic of air per minute. That should be enough to clear the air in and around the work bench about every 6-7 minutes. Since you actually spray into the booth, I'd guess that it will remove the air in the immediate vicinity much quicker than that.
Spraying with a spray booth like this will be much safer than in the past and should eliminate most stray paint particles that may be floating around in the area. It should also remove a lot of the smells associated with spray painting that somehow make their way all over the house during the winter months. It never hurts to be a little more safe than sorry. Thanks Santa!
