Air Movement Guidelines:

• When used for cooling people, choose a Revolution® HVLS Fan that moves air a minimum of 2 miles per hour in the targeted zones.
• The minimum air speed needed for destratification is 1/2 mile per hour.

   

• Air speeds are the average velocity for each fan and zone.
• Air speeds were measured 48" from the floor.
• Industrial Fans were mounted 30' from the floor.
