Plenum fans are designed for general HVAC applications where large volumes of clean air are required at low to moderate pressures. Backward inclined airfoil impellers provide high efficiency, performance and sound characteristics needed for the most stringent HVAC applications. With housed or open designs, as well as direct or belt driven options, plenum fans provide the flexibility to match the performance and application at the highest efficiency.
