F4-72 Centrifugal Fan

Firefighting and Ventilation Series

Structural Design:

The 4-72 centrifugal fan is an efficient and energy-saving centrifugal fan. Its wing-type blades, curved impeller front plate, and cone-shaped inlet collector contribute to excellent aerodynamic performance. This fan has been widely used for many years in China’s economic construction projects. There are four types of drive modes:

  • Type A: Direct coupling drive between the impeller and the motor.
  • Type B: Belt drive with the pulley located between two bearings.
  • Type C: Belt drive with the pulley mounted outside the bearings in a cantilevered position.
  • Type D: Coupling drive between the impeller and the motor.

Applications:

The F4-72 corrosion-resistant centrifugal fan is suitable for installation and use in chemical plants, laboratories, basements, bathing pools, and other places that handle corrosive gases, acidic and alkaline gases, or gases with high humidity.

The B4-72 explosion-proof centrifugal fan is designed for explosion-proof applications. It is suitable for installation and use in boiler rooms with fuel or gas, workshops with high dust concentration, oil depots, gas stations, and warehouses storing explosive materials, and can handle gases that are flammable, explosive, or volatile.
