Usually industrial dust concentration reaches a certain level (that is, the explosion limit), such as the case of electrostatic discharge sparks or other factors such as the ignition point, it is very easy to cause explosion and fire. At the same time in the operation of the dust collector dust in the air contains more moisture and oily, hygroscopicity and easy dissolution of dust, the dust appears on the surface of the clear and difficult ash, and the needle felt combines the advantages of waterproof and anti electrostatic needle felt and ordinary filter compared, not only has oil proof and damp proof characteristics, but also has anti- static effect.
