Exhaust Fans

Exhaust fans help to force out stale air and pull fresh, clean air through your facility for a more comfortable working environment. Belt-driven exhaust fans have durable galvanized steel blades to handle large volumes of air at low static pressures, and are available in vertical roof and horizontal mount wall configurations. They feature variable pitches and adjustable pulleys to optimize performance. Direct-drive models are available in a wide range of sizes and airflows. These medium-performance and high-performance exhaust vent fans can be found with polypropylene propellers and fiberglass frame construction for corrosion resistance. Grainger has ventilation fans available in a variety of sizes and motor horsepower configurations designed for your specific application.

Hello. There is a 12" x 12" round opening with a large square cover over it. The fan is missing, but the wiring and switch should work if I can find a fan to put in there. I would like something quiet but strong enough to exhaust smoke. Any ideas appreciated!

I have a wood boiler in my basement, and sometimes the smoke comes out when I open door to load wood. Need some kind of fan over door that would connect to 6"insulated flu to exterior. The fan would need to tolerate some heat-nothing major. The smoke seeps into rest of house and I hate it..

Answer: 
You need to talk with a HVAC specialist, this could happen for many reasons. The wood's boilers are vented by gravity not by a power fan, check your flue. If the smoke came to your house the CO (carbon monoxide) also get in your house, by sure you have CO detectors in your house, CO could kill you!

Answer: 
NO and may be YES!
The most probably is that the size (capacity CFM power) of the exhaust fan that you need is bigger that the one you are looking, the area of an office is usually bigger that that bathroom, the size of your exhaust fan depend on the office area(Sq Ft that you have) May be next time ask " I have an office that is #### Sq Ft, what exhaust fan may I use?"

I have four exhaust vents in my triple wide mobile home that exit through the roof. Two bathrooms, a laundry room, and over the stove. The current exhausts allow hot/cool air to come into the home when vent is not turned on. Do you have venting that when turned off have baffles that stop hot/cool air from coming in?

Answer: 
I believed that the all the exhaust fan that you already have in your home; had installed a backflow damper, this damper will prevent that the cold or hot air will get in the house whenever the exhaust fan is off, the air flow (from the exhaust) push the damper and open it. Check them, they should open and closed free, sometime they got stocked opened or semi-opened.
