To select a VentCool Whole House Fan follow these four steps :
STEP 1: Choose Series Features
Choose the VentCool series based on the features you want like type of motor and damper.
STEP 2: Size The Fan
The fan CFM capacity is related to the square feet of the home. Note: When the square feet of home is between fan CFM capacity, select the next larger fan CFM capacity.
For effective free cooling the CFM of the fan should be equal to the square feet of the home.
Minimum Fan CFM = Floor Area (Sq Ft) x 1
For faster free cooling the CFM of the fan should be equal to two times the square feet of the home.
Minimum Fan CFM = Floor Area (Sq Ft) x 2
STEP 3: Exhaust Requirement
Per Title 24 guidelines, make sure there is one square foot of NFVA (Net Free Vent Area) per 500 CFM fan capacity.
Determine NFVA: Fan CFM ÷ 500 = NFVA required
After determining the minimum NFVA needed, the existing vents in your attic will need to be measured to verify you have enough venting. Count and measure each type of attic vent and multiply by the reduction factor. This will determine the actual NFVA needed in your attic. Note: Louvered vents have a .75 reduction factor.
STEP 4: Intake Air Requirement
For peak fan operation, an adequate amount of air must be supplied through open screened windows and doors.
Determine Air Intake: Sq Ft Intake = Fan CFM ÷ 250
