Backward Inclined Aerofoil Fans (Radial flow)

Backward curved industrial fan impellers can be fabricated using a fan blade with an aerofoil cross section. Particular backward inclined aerofoil industrial fan designs of this nature can achieve very high efficiencies. The backward inclined aerofoil fan is commonly used in air management applications where large amounts of air are required such as commercial building and car park ventilation. The aerofoil fans are generally considered to be quieter than other designs

This industrial fan impeller design is efficient and suited to clean air application. Like the backward inclined fan it can be adapted to suit a double width double inlet arrangement. This impeller type is generally suited to an application which requires high performance fan efficiencies whilst achieving lower noise levels at the relevant duty.
