Excellent fan
PostedJuly 2, 2012
This fan is worth the money. It is very well built and does a great job pulling the cool air into the house on the cool summer nights. This is very well built, all the joints are welded instead of bolted like on lower quality fans.

how do I know what size exaust fan to us for commercial bathroom

Field of Industry:: Stone fabrication
Product used for:: buisness restrooms
Years purchasing from Grainger:: 10
You will need about 6 air changes per hour for a commercial bathroom.
First, you need to determine the cubic feet of air in you have in your bathroom. To do this measure the square footage of the floor and multiply by the ceiling height. For example, a 10' x 10' bathroom with an 8' ceiling has 800 cubic feet of air (10x10=100, 100*8 = 800).

Then multiply your cubic feet by the number of air changes desired, in this case 6. (800*6=4800, in the above example

Finally, divide by 60 to get the CFM needed from your exhaust fan. In this example 4800/60 = 80.

So, in a 10'x10'x8' bathroom you would need a fan that moves 80 CFM.

Hope this helps.
