Product details
Application of 4-2 × 72 centrifugal fan:
It can transport air and other gases that are non self igniting, harmless to the human body, and non corrosive to steel. Viscous substances are not allowed in the gas, and the content of dust and hard particles should not exceed 150mg/m ³. The gas temperature shall not exceed 80 ℃. This fan has good aerodynamic performance, balanced operation, low vibration, high efficiency, and long service life. Widely applicable for indoor ventilation and air exchange in industrial and mining enterprises, large buildings, hotels and restaurants.

4-2 × 72 centrifugal fan structure:
The fan is composed of an impeller part, a casing part, an air inlet, a bearing seat, an electric motor, etc. It has the characteristics of compact structure, easy installation, and convenient maintenance.
1. Impeller: Composed of two impellers with different rotation directions, each impeller has 10 wing shaped blades and an arc-shaped front plate. After dynamic translation correction, it runs smoothly.
2. Air inlet: Steel plate made into a conical arc-shaped flow channel.
3. Shell: Made of steel plates welded into a snail shape, with bearing brackets and fan bases.
4. Bearing seat: Double row radial spherical bearings are used and lubricated with calcium nanobase grease.
Performance parameters of 4-2 × 72 centrifugal fan
4-2 × 72 centrifugal fan type:
1. The fan can be made in two types: right-handed or left-handed. The outlet position of the fan is represented by the angle of the casing outlet, which can be 0 °, 90 °, or 180 °
2. The fan adopts dual suction intake, with machine numbers 6E, 8E, 10E, 12E, 14E, 16E, 18E, and 20E. (Transmission mode is E)
