Cheap & Easy Exhaust Fan

Nicely done.

Do you live in a place that gets a “real” winter, and—if so—what do you do about that leaky spot? Did you hinge the whole thing to allow you to close the (presumably) window behind it?

excellent idea, this is my next project

Show upgrades always rock!

The window closes without moving the fan at all, and yes i get a real winter, it isnt uncommon for us to get 6 feet of snowfall a year, during the winter season I have a cover to put over the window and the cover has a door on it so when I want to use it in the winter time I open the window, open the outside cover and away I go.

Good idea. I am going to make of these to ventilate my shop.

-- Remember, measure twice, cut once

I would only caution you about flammable vapors and using an ordinary household fan for exhausting them. If the vapor concentration builds up, you could have a nasty fire or explosion.

Instead of drawing the fumes through the fan, try to use positive pressure in the room to push the fumes out through the open window.

Most commercial exhaust fans have explosion proof motors.

Thought I’d put this out there for everyone since this is National Fire Prevention week. Please check your smoke detectors and fire extinguishers regularly.

Keep it SAFE out there!

Yeah, I noted this when I made the fan, any finishing I do is out of a can, I don’t spray. Spraying would increase the risk exponentially, also if you spray most local laws require you to have special filters and some local laws won’t allow you to spray in your residence at all, just something to watch out for.

The use of filters may keep the kids next door from throwing crooked fast balls, or walking sideways…..lol

-- Can't never could do anything, to try is to advance.

I can only echo KnotWright’s statement about explosion proof motors.
