AC Forward Fans

AC forward fans are forward-curved centrifugal units running on AC mains for constant-speed air handling and HVAC supply where no speed control is needed. The many shallow blades give compact volume at low pressure and low cost, with PSC or external-rotor motors. For a fixed air handler duty, the simplicity beats paying for a variable-speed drive.
