How is HVLS performance measured and what should I look for?

Not all HVLS fans are created equal and are not the same. When it comes to performance, look for:

  • Maximum Cubic Feet per Minute (CFM)
  • Efficiency Cubic Feet per Minute per Watt (CFM/W)
  • coverage area in square feet
  • dBA at Maximum RPM (needs to be less than 85 dBA; the rate at which long or repeated exposure to sound can cause hearing loss)
