A new high-performance fan wheel is available in seven sizes and two configurations for FANWALL air-handling units from Governair, Huntair, Mammoth, Temtrol, Venmar CES, Ventrol, and Webco. The improved aerodynamic shaping of the blades, shroud, and cones, as well as the dampening effect of the polymer material, reduce sound tones from the impeller and motor, resulting in a typical sound reduction of 5 dB of fan-blade-passage frequencies on inlet and discharge.
