Greenheck SP-A125 Fan

The Greenheck SP-A125 Fan is a heavy-duty, 115V 1100RPM ceiling exhaust fan engineered specifically for high-efficiency ventilation in residential, multifamily, and commercial applications. As a direct-drive centrifugal unit, this model is built for clean air service where low sound levels are non-negotiable, delivering between 109 and 144 CFM depending on system static pressure. The PSC motor is thermal overload protected and speed-controllable, allowing contractors to fine-tune the airflow to meet specific ASHRAE requirements or local code. Its galvanized steel housing is fully insulated with acoustic material, effectively dampening motor vibration and air turbulence to achieve ultra-quiet operation as low as 0.7 sones at 0.25 in. wg. Designed for horizontal mounting, the SP-A125 features an 8" x 6" rectangular discharge with a spring-loaded backdraft damper to prevent outdoor air infiltration and duct rattling, ensuring a high-performance, professional-grade install every time.
