Air conditioning fan, air conditioning fan is mainly composed of casing, impeller, inlet and external rotor motor.
Case: it is made of galvanized steel bite, or made of high quality cold rolled plate. Its contour is smooth, heat resistant, moisture resistant and durable.
Impeller: the forward multi wing arc blade is riveted with the front disk and middle plate. Through strict dynamic and static balance correction, it ensures smooth operation, high efficiency and low noise.
Air inlet: through the mold processing, the cross section with the axial direction is streamlined, making the gas smooth and small resistance.
External rotor motor: the two ends of the motor are fixed on the air inlet, and the impeller is directly connected with the rotating shell of the motor, thereby reducing the transmission loss and improving the efficiency of the fan.
