Model SP-A50-90-VG-QD is an ENERGY STAR® certified bathroom exhaust fan featuring a Vari-Green, EC motor allowing for increased energy savings. This fan is capable of operating at a constant CFM up to 0.875 in. wg, providing continuous or intermittent ventilation while maintaining extremely low sound levels. ENERGY STAR® rated bathroom fans utilize 70% less energy than a stand fan, saving on energy costs.
Greenheck’s Vari-Green (VG) Electronically Commutated (EC) motor combines motor technology, controllability and energy-efficiency into one single low maintenance unit and is the industry's first fully controllable motor. The EC motor operates on AC power that is converted to DC – providing more efficient motor operation as compared to an AC operation. The controllability of the Vari-Green motor allows communication compatibility with a variable volume system. This allows speed adjustment of the motor to meet the needs of the system to exhaust air as needed and reduce overexhausting conditioned air.
