I just finished painting the engine & engine compartment compartment of my Chevelle. Anyway, I have been researching exhaust systems for home garages for over a year. I finally, had some painting to do, and decided to take the plunge. The garage is detached from the house. Here is the setup:
Squirrel cage fan from old furnace - moves a ton of air.
Duct taped an interior door opening that divides the garages with 10 mil plastic.
Cut a hole in the plastic the size of the opening in the squirrel cage.
Duct tape the plastic to the fan.
Duct tape a $1.99 pleated purolator filter to the opposite side of the plastic
The beauty part is that no paint made it beyond the filter
Minimal buildup in the shop while I was painting, and minimal overspray. And...the motor was on the outside of the fumes, so I had less chance of blowing up
I built a dog house to mount on the back of the garage so I can mount the fan permanently, and I am going to secure another to put in the attic to provide positive pressure for future painting. Also, thumbs up
for the Neoterik fresh air system. If I were purchasing now, I would get a 2 man setup, so you can disconnect in the shop when your done spraying & reconnect at your mixing station without having to drag the hose through a door. Hose is a little bulky, but it works nice. Just thought I'd share.
