Filtered Supply Fans


Filtered Air Supply Fan, Roof Mounted


The FSR is an axial flow, filtered supply fan featuring Aerovent’s Macheta® impeller. The FSR is designed for roof mounted applications requiring the supply of high volumes of filtered air. Specially constructed with a steel hood that is well above the roofline, so it will not pick up undesirable hot air from other exhausters or from heat radiating off the roof.
