4-72 centrifugal fan Industrial induced draft fan 5.5kw air capacity
4-72 centrifugal fan is a common exhaust fan products, because of its high efficiency, widely used in
industrial and mining plants and civil buildings, large public buildings, power plants and other places,
can also be used as air treatment facilities, hot air circulation facilities supporting equipment. It is
divided into two categories: 4-72-A and 4-72-C. Because its impeller adopts backward tilt type, it is
not easy to adhere to dust and other media, and the motor adopts imported bearings. 4-72 centrifugal
fan adopts reasonable impeller Angle design according to air flow mechanics, no mechanical friction
during operation, reasonable blade shape line to minimize noise; The noise generated by the 4-72
centrifugal fan is high-frequency noise, and it can be soundproofed as long as there are obstacles.
