A whole house exhaust fan or wholehouse fans are a great way to move or circulate air, cool your home, reduce air conditioning costs and utility bills. These fans come in direct drive or belt drive versions. It is important to buy a quality house fan. Cheaper units can be noisier, less energy efficient, and less effective. Industrial Fans Direct only offers quality whole house attic fans for all home sizes and types.
Sizing Your Whole House Fan or Attic Fan:Whole house fans are rated by CFM (cubic feet per minute) air exchange capacity. Well-established Industry standards recommend using a fan that will change all of the air in your house once every 1 1/2 to 2 minutes (in cooler climates, once every 2 to 3 minutes).
To determine the proper size fan, multiply the square feet in your home by the ceiling height. Select the whole house fan which has equal or greater CFM performance as the calculated figure.
