It looks like most people are using simple fans and blowers. Most modern box fans use induction motors which are spark free. It's the switches that make sparks, so you have to turn everything on ahead of time and then leave it all running until danger is gone.
I was just thinking too that heat's not that big a deal if you have a sealed paint booth with negative pressure that is vented with a blower going outside then the rest of your garage has no fumes and you can use any heat source you want to use. I still don't like flame based heat in a garage.
If you build a sealed negative pressure booth you need to have a filtered air input built - just build a frame for a regular furnace filter. |
negative pressure gets the vapour out but it also means you get dust sucked in through the clean air side so it is not desirable. in a perfect world you want a second slightly larger fan sucking clean air in past an a/c filter or something similar that is finer than the exit furnace filters (which are course enough to catch the paint). I think I am going to pass on the larger fan but I will use a fine filter and I may use a smaller fan.
also these designs aren't really dealing with winter conditions. the garage doors are wide open allowing a ton of ambient ventilation for whatever gets out the booth. i have to be way more careful on adequate venting if i add a heater and a closed garage door to the equation.
