These types of high-flow, frequency controlled direct drive fans are typically used in ventilation, heating, AHUs, air curtains and heat recovery applications.
Torin-Sifan FCDDC fans are a range of forward-curved fans powered by intelligent, controllable and highly efficient three-phase AC motors with an integrated frequency inverter controller. Constant flow, constant pressure and constant speed are achievable with this range, whilst being extremely quiet due to the elimination of mechanical resonances.
Impeller sizes range from 201-178 (7/7) to 321-321 (12/12) driven by motors with input power ranging from 630 W to 1.5 kW. Fan cases and impellers are manufactured from corrosion resistant galvanised steel.
