Axial flow fans are widely used. Some industries need to add specific functions, such as explosion-proof axial flow fans, here, we introduce the knowledge of explosion-proof Fan: explosion-proof refers to the explosion-proof in the case of danger can also be normal work, can resist the impact and heat so called explosion-proof fan, explosion-proof production must be considered from three necessary conditions, limited one of the necessary conditions, it is limited the production of explosion. Select the corresponding explosion-proof instrument and electrical equipment, the standard structure is: explosion-proof type, increased safety type, positive pressure type, sand-filled type and oil-filled type. Points for attention in selecting and purchasing explosion-proof blowers: According to the amount of wind, voltage, speed and so on required by the blowers, determine the type of their own blowers, select the type of axial flow blowers with lower noise ratio, pay attention to the internal inspection of the casing when selecting and purchasing them, to prevent tool or debris left behind.
