High Efficiency EC Direct Drive Fans ECDDC 321-321 (12/12)

This type of high-flow centrifugal fan is typically used in ventilation, heating, AHUs, air curtains and heat recovery applications. 

Torin-Sifan EC direct drive fans are a range of forward-curved centrifugal fans powered by intelligent, controllable and highly efficient EC motors with on-board drive electronics. Impeller sizes range from 201-178 (7/7) to 381-381 (15/15) driven by motors with input power ranging from 550 W to 1.6 kW. Fan cases and impellers are manufactured from corrosion resistant galvanised steel. 

The latest generation EC direct drive range of forward-curved fans from Torin-Sifan far exceed the requirements of the Energy Related Products Directive (ErP), January 2015.  These fans use high efficiency EC motors that provide 30% energy savings when compared to a traditional AC motor.
