WARNING: FANS ARE NOT MEANT TO BE OPERATED IN WINDY CONDITIONS.
The minimum distance of a fan to a wall or similar obstruction should be no less than 1.5 times the diameter of the fan.
The goal of this diagram is to determine the proper extension length to maintain a minimum blade clearance of 15% of the fan’s diameter. The extension
lengths above are minimum recommendations only, based solely on roof pitch and fan diameter. Other factors must be evaluated when determining extension
requirements. In addition, MacroAir strongly recommends that the fan blades must be a minimum of 10 feet (3.05 meters) above the floor. Contact our
technical department for assistance with fan placement and extension selection (technical support contact information can be found on page 36).
