Hello All,
I have run the numbers based on the information provided on this website http://modelpaint.tripod.com/booth2.htm to determine the type of fan required.
My issue is going to be price here. Based on my calculation I'm looking at needing a fan that's roughly $400. The fan needs to be capable of venting through roughly 30' of duct work (as the nearest exterior wall is roughly 20' away + 90* elbows etc.)
I do have some options though but don't know if they are reasonable, which is where I'm looking for help.
Option 1 (less then ideal) I could move the booth to the exterior of the house, but where I would have it now fits in with the rest of my modelling supplies/workbench. Then I could just vent directly out through either a window or install a vent.
Option 2 (more ideal) I could vent into the garage as the wall that the booth is on is the garage wall. I just removed the central vac and have easy access to drill a hole through the wall and install a vent there. I am concerned about paint fumes BUT, i would be the only person painting or working in the garage, and i cant do both at the same time :) would there be a concern? my garage is not air tight anyways, but i would like to avoid having to constantly go and open the door just to vent it after spraying.
Option 3 (least ideal) buy the $400 fan.
Also, are these 'squirrel cage' blowers really the way to go? I read the worries about sparking with an kitchen/bath fan. is this a legitimate concern?
I'm a part time modeller but I do have some permanent space to set something up. That space just happens to be in the laundry room so i don't want it to stink of paint fumes throughout the day. I don't have the ability to have a booth that i move around the house when i want to spray so while I'd like to have something permanent, i also want something functional and hopefully, cost effective. any help is greatly appreciated.
Thanks,
Matt
