The SP-A50-90M-VG-QD is a motion sensing, 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. With an integral motion sensor, this bathroom fan automatically turns on within the space once movement is detected. After a specific amount of time lapses, the fan powers off ensuring its only operational when there are occupants in the bathroom. This increases occupant comfort while minimizing energy costs. Motion sensing bath fans are ideal for residential and commercial bathrooms and multi-family dwellings.
Motion Detecting Grille
A motion detecting grille is a great, low-cost way to save money on energy bills. Motion detectors use a passive infrared motion detector to automatically turn the fan on when a change in motion is sensed. They have a viewing area of 180 degrees, however they must be placed in the line-of-sight.
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.
About ENERGY STAR®
ENERGY STAR® is a market-based partnership formed to reduce greenhouse gas emissions through energy efficiency and make it easier for consumers to identify energy-efficient products that offer savings, performance, features, and comfort.
To earn the ENERGY STAR label, products must meet strict energyefficient standards set by the U.S. Environmental Protection Agency (EPA) for energy consumption, air and sound performance.
