Hi all, I’m looking for some new ideas for ventilation in my spraybooth (10’x10’x8′) have always used my box fan with funace filters which works great for latex,acrylics,primers but obviously not for lacquers and such. Exp.proof fans are pricey. I’m thinking about a presureized type of set up so the fans would be on the opposite side of the fumes. Any feedback would be a great help. Thanks…

You can set up a perfectly functional spray booth/room by putting the fan at the intake. We have a professional spray facility that sends the air thru filters in the ceiling into the room. It takes the overspray effectively and exits just because of the pressure created in the room. Nothing but baffles on the way out.

Hello finicky, as a fireman, the thought of sucking out smoke from a building has changed to blowing fresh air into a structure and pressurizing the room and controlling the direction of smoke to an exit. As an alternative to using the box fan sucking the overspray thru the ac filters-like I do (I dont spray flammables)perhaps you can use multiple fans to "pressurize" your garage/spray booth and leave an outlet for the overspray to exit. You still have to be quite careful for the explosive limits of flammables-many points of ignition lurking!
good luck and change filters often
