B4-72 centrifugal fan is a low pressure but large volume fan. It also named as explosion-proof centrifugal fan (represented by “B”), It is used for air ventilation in environment where contain flammable substances, but it is not suitable for using in the temperature of the conveyed gas exceed 80 °C. The B4-72 centrifugal fans have two models of 4-72-12 and 4-72-13. They have № 2.8, 3.2, 3.6, 4, and 4. There are totals of 12 numbers such as 5, 5, 6, 8, 10, 12, 16, 20 and etc.
Industrial applications to 4-72B centrifugal fans
The 4-72-B/F centrifugal ventilation fan is mainly used to ventilate or transport air in places where contain flammable volatiled. However, the conveyed gas must not contain viscous substances, the dust and hard particles should not exceed 150 mg / m3, and the gas temperature should not exceed 80 °C.
Types of B4-72 Centrifugal fans
There are two types of B4-72 fans, B4-72-12 and B4-72-13. They have 10 machine numbers № 2.8 ～ 12. B4-72 centrifugal fan has the same air performance. And structure as the 4-72 except that the motor uses an explosion-proof motor. Models 4-72-12 and 4-72-13 are the same—the air performance of the model is exactly the same. But the outline structure is slightly Different, 4-72-13 uses B3 motor, with bracket or integral bracket.
