EC high efficiency brushless DC centrifugal fan

EC series high efficiency centrifugal fans are driven by a new brushless DC external rotor motor and controlled by sinusoidal voltage vector; Realize the maximum torque / current ratio of the motor according to the load characteristics of the fan; Smooth speed regulation within the set speed range; With soft start characteristics; Automatic protection can be realized; It has the advantages of low noise, high efficiency, convenient speed regulation and fixed load, fills the domestic gap and is at the leading level in the same industry.

The efficiency of EC series high-efficiency centrifugal fan meets the energy efficiency limit of level 2 and above specified in the national energy efficiency standard GB 19761 ventilator efficiency limit and energy efficiency label, which is of great significance to fan energy conservation.

EC series high efficiency centrifugal fans can be widely used in air conditioning, ventilation, purification, heat dissipation and other fields without acid, alkali, corrosive and combustible gases and dust particles of no more than 150mg / m3.
