what size shop is it

A two horse barn fan works pretty good, you need a sealed motor for doing painting (explosion proof). I had mine mounted in the ceiling and blowing into the attic space where I had put in a larger attic vent to handle the extra airflow, kept the garage cool in summer too. Mine was mounted in the access hatch and flipped for attic access. All I had to do was wire a plug and switch to turn the box power on and off, I thought it was pretty slick.

I didn't much care if there was extra dust in my attic.

it is a 21'x21' detached garage just tired of opening the door to grind or weld to get rid of the fumes thought about installing a attic fan in my window , did not know if that would work considering the cfm it has.

i have a friend that replaces heat pumps and i was at his house oneday a seen one torn apart to take off for scrap
the fan and housing unbolted from top of the unit there for it had its own frame/and grill over the blades tokeep out the birds anyway i took it home tested it out. i built a ply wood box and a door that opens and closes on the inside with a string cut the opening for the fan and mounted in place with screws. it has worked great for the last 4 years my shop is 22x20 and it pulls lots of air
u could buy louvers but i got no money. no probs yet with rain blowing in
someone is always updating a heat pump should be easy to find a old one cheap that will work for u. just dont do alot of painting it is not exsplosion proof

On page 3 and 4 you will see some home made insulated vents, they are user friendly and always work good, anyway in here. http://www.1969supersport.com/paintroom.html

Bought this item on EBay for about 75.00, I searched for a few weeks but there were lots of choices, hardwired inside an existing window frame and works great. Has a totally enclosed motor..just have to remember to turn on the fan BEFORE spraying so no sparks at the switch...louvers work good..I made the whole frame removeable so I can pop the window sash back in when needed. Rated at 5450 CFM... marginal for my space but works well for me.
