The EC centrifugal fans are designed especially for supply & exhaust ventilation and air conditioning systems, where space is at premium and low noise levels are of great importance. Due to the adoption of electronically commutated (EC) external rotor motor, these centrifugal fans are featured by minimal acoustic noise and reduced overall size since the external rotor is directly attached to the fan impeller.
