* Standard molded fan guards allow for extended air throw; optional wire guards promote air diusion
†
Air throw data based on 12-ft. high ceilings with no obstructions where velocity drops to 50 FPM
‡
For EC motors, use 60 Hz capacity and airow values (Units with EC motors operating at 50 Hz will
not see a reduction in performance due to the electronic control of the motor)
