4-72, b4-72, and f4-72 centrifugal fans

Performance Overview

   Type 4-72 centrifugal ventilators can deliver air and other non-natural, harmless to humans, and non-corrosive to steel gases. There must be no viscous substances in the gas, and the dust and hard particles contained should not exceed 150 mg/m³. The gas temperature must not exceed 80°C. These ventilators feature excellent aerodynamic performance, balanced operation, low vibration, high efficiency, and long service life. They are widely used in industrial and mining enterprises, large buildings, hotels, restaurants, and other indoor ventilation systems.

Model B4-72 is an explosion-proof centrifugal ventilator. It primarily consists of an aluminum impeller, casing, air inlet, and an explosion-proof motor. It can be used for ventilating flammable and volatile gases, and its performance and installation dimensions are identical to those of model 4-72.

The F4-72 model is an anti-corrosion centrifugal ventilator. It consists mainly of an impeller, casing, air inlet, and other components made of stainless steel (or fiberglass) along with a motor. It can be used for conveying corrosive gases, and its performance and installation dimensions are identical to those of the 4-72 model.
