Flighting Speed is calculated using a 1750 rpm electric motor. To determine flighting speed (rpm), divide the
motor speed (rpm) by the outside diameter of the large unload pulley, then multiply by the outside diameter of
the small motor pulley. Example: 1750 rpm / 15” x 4-3/4” = 554 rpm.
If a slower flighting speed is desired, install a smaller motor pulley.
