Shop exhaust fan

[42FarmallMatt]

Hello all,

With the colder months approaching I'm getting what painting I can get done while the weather is still nice here on the east coast. I was curious if anyone had any methods of securing an exhaust fan at a window to your shop so you can do things during the cooler months and not fill your shop up with dust or overspray. I may do some occasional painting and sanding/sandblasting but won't if I can't keep dust under control. Any input is appreciated.

If you don't want to dirty up your shop, try setting up a clear plastic room outside, with light framing, off a door or on the sunny side of a wall. I've done it once and it worked great. Used a cheap box fan to push heat into the room and opened the plastic enough to vent it.

A lot of people use all kinds of fans including a common window fan. If you ever look inside the motor one of these fans you would see it caked up with paint. Then you have to remover an electric motor often creates a spark inside the motor. With dust you could blow it with compressed air from time to time but paint stays. Using a fan for paint you could use a common fan to bring in clean air but for exhaust you need one with an explosion proof motor. It's sealed to prevent paint and the fumes from getting inside the motor. They aren't cheap but cheaper then a fire.

Most insurance companies are satisfied with the fan being belt driven by a motor off to the side so the fog doesn't go directly over the motor.

My exhaust fan draws enough air to reverse the air flow up the furnace vent pipe, so what I do when I'm painting in cold weather is warm the shop up with the exhaust fan off, then shut the furnace off and turn on the fan and spray my paint. Then when I'm done painting and the fog is cleared out of the shop turn the fan off and the furnace back on.

I use a common old metal box fan that simply fits into my window.

Reminder, however much you want going out you have to have that much replacement air coming in somewhere.

To be safe with particulates and chemicals, get a good quality axial flow fan which will move a lot of air and change the air in the room every 5-10 minutes. Do the math using the room cubage and the fan's specifications. As has been said, you need to assure air inlet, as a door or window open.

What do you guys think of having an intake fan in one window to bring fresh air in and a exhaust fan in a separate window on the other side of the shop to expel dusty air? Pretty much like what showcrop is doing. My shop is 24x24 with 8' wall height. Found some fans at Lowes with a "weather" rated motor for window use.

Not necessary. 1 power fan and 1 vent.

Which is pretty much what I am doing. I have an exhaust fan and then depending on where in the building I am spraying, or outdoor air movement, I will "steer" the air flow by the amount that I open two doors and two windows.
