How To Size a QuietCool Fan

1) Determine square footage of entire home
  • Multiply by 2 and by 3 to determine the needed range of Cubic Feet per Minute (CFM)
  • Square footage x 2 = minimum CFM, square footage x 3 = maximum CFM
  • Model numbers of fans are the approximate CFM, calculations based on 8 – 9 foot ceilings
  • Example: Manufacturer’s recommendation for a 2000 square foot home is 4000 – 6000 total CFM
  • Superior System = 3 CFM / square foot of living area + attic gable fan + garage fan
  • Advanced System = 2.5 CFM / square foot of total living area + attic gable fan
  • Basic System = 2 CFM / square foot of total living area
2) Select a Central (1 fan) or Zoned (2 + fan) system
  • Central (1 fan) system:
  • Install at top of stairs or in middle of single-story home
  • Breeze is controlled by which windows are opened
  • Bedroom doors must stay open at night to cool bedroom and feel breeze
  • Zoned (2 + fan) system:
  • Install main fan in center of home
  • Install additional fans based on lifestyle and budget. For instance, install in bedrooms when homeowners sleep with doors closed, office with computer equipment, hot bonus rooms, etc
  • Add CFM of all fans together, total CFM should fall within minimum and maximum CFM range
3) Pick which specific fan you’ll install. If you’re a contractor, Stealth Pro or Trident Pro are best
  • Stealth PRO 1.5, 2.5, 3.3, 4.8, 6.5 (1500 – 6500 cfm)
  • ECM motor – AC/DC Brushless
  • Most energy-efficient motor
  • Will save homeowner most energy and money over time
4) Determine venting – amount of open window for air in AND amount of attic ventilation for air out
  • Calculation: total CFM to be installed, divided by 750 = net square footage of needed ventilation
  • Example: When installing Trident Pro 4.8, need approximately 6-1/2 total net square feet of window(s) open for air in and 6-1/2 total net square feet of attic ventilation for air out
