4-72 series centrifugal fan is primarily designed for indoor ventilation purposes in factory and other large buildings. It works by delivering air or other non-flammable and harmless gases that will not corrode steel into the interior space, and exhausting those flammable and volatile gases out of the room.

Manufactured according to the industrial standards, 4-72 series industrial fan allows for no viscous material in the gas. Dirt and other large particle is no more than 150mg/m³ and gas temperature is lower than 80℃. Besides, for the convenience of users, we have employed an integral structure of fan and motor in our newly designed 2.8A-6A series industrial centrifugal fan.
