This impeller diameter 133mm backward tilt centrifugal fan adopts external rotor brushless DC motor, Impeller material is plastic PA66+GF25, 0-10VDC/PWM control input, technical output, locked-rotor protection, reverse polarity, over-voltage protection, soft start protection, rated voltage 230V, applied to air purification, AHU/FFU. Low power consumption makes it more energy saving, compact structure takes up less space, large air volume makes the equipment more efficient and strong purification capacity; The fan can also operate normally in an environment of -25ºC to 65ºC, greatly prolonging the service life of the purifier; The fan blades are designed aerodynamically to make the purifier run more quietly. The EC fan is equipped with various signal output ports. The EC fan features high intelligence, high energy saving, high efficiency, long service life, low vibration, low noise, and continuous operation, with low loss and high efficiency. Low pitch operation, quiet and dust-free, EC fans have obvious advantages in noise reduction, compared with ordinary fans, bring clean and no noise trouble. Whether it is household purification equipment or highly rigorous medical industry, clean engineering, backward centrifugal fan plays its biggest role.
