FAN
PLACEMENT - UMH
AirEco Dimensions
WARNING: FANS ARE NOT MEANT TO BE OPERATED IN WINDY CONDITIONS.
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, OSHA requirements state 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 37).
