Application of explosion-proof centrifugal fan
The 4-72 centrifugal fan is mainly used to ventilate or transport air and other unnatural, non-explosive, non-volatile, harmless to human body and non-corrosive gases to steel for indoor ventilation of large factories and large buildings. The gas conveyed by the centrifugal fan does not contain viscous substances, the dust and hard particles contained in it are not more than 150mg / m 3 , and the gas temperature does not exceed 80 ¡ã C.
The performance, options and foundation size of B4-72 centrifugal fan are the same as those of 4-72 type, which can be selected according to its sample. The fan mechanism is basically the same as the 4-72 type. NO.2.8--6A uses a B35 motor with a flange and a ground foot. NO.6--12C and D motors use the YB series corresponding to the Y series in the table. , The installation form is B3.
F4-72 centrifugal fan is made of FRP corrosion-resistant material, and its performance and foundation size are the same as 4-72 centrifugal fan.
