4-72C typecentrifugal fanIt is generally used for ventilation and air exchange in factories or larger buildings. It can input and output gas. The gas it transports is air or other non self igniting, non-volatile, harmless to the human body, and non corrosive to steel materials. The gas shall not contain viscous substances, and the dust and hard particles shall not exceed 150mg/m3. The gas temperature shall not exceed 80 ° C.

The type

Centrifugal fans can be made in two types: right-handed and left-handed. From one end of the motor, if the impeller rotates clockwise, it is called a right cyclone machine, represented by "right", and vice versa, it is called a left cyclone machine, represented by "left".

The outlet position of the fan is represented by the angle of the air outlet of the casing. 4-72C type

centrifugal fan

№ 3-6 are all made into one type at the factory: the adjustment range of the air outlet position is 0 °~255 °, with an interval of 45 °, and the transmission mode is A-type transmission; The positions of the air outlets numbered 7-12 are fixed in three ways: 0 °, 90 °, and 180 °, and cannot be adjusted; The transmission mode of No. 7-12 is C-type transmission. Please specify when placing an order.

☆ Structure of centrifugal fan

Fans numbered 3-6 are mainly composed of impellers, casings, air intakes, and other parts paired with direct connected motors; In addition to the above-mentioned parts, there are also transmission parts such as No. 7-12.

(1) Centrifugal fan impeller:It consists of 10 backward inclined arc thin plate blades, curved front plate, and flat rear plate, all made of steel plate, and has undergone dynamic and static balance correction and overspeed operation experiments. It has good air performance, high efficiency, and stable and reliable operation.
