Effect of bag filter is generally made from high performance electrostatic filter material, each filter bag filter bag edge fusion using ultrasonic, with good air tightness and the bonding strength, not due to the high air pressure generated when gas leakage or rupture and affect the filtration efficiency, each nonwoven filter bag has six spacers to average distribution of the ultrasonic jointing in the bag width, the spacer in addition to have all the wind effect, Its main function is to control the filter bag under wind pressure from excessive expansion of mutual shading, and reduce the effective filtration area and effect.

       The bag filter has large effective filtration area, large dust capacity, small resistance and large ventilation volume. The frame and support frame can be reused, only the filter bag needs to be replaced when the filter is replaced, and the operation cost is greatly reduced. Widely used in electronic, pharmaceutical, medical, food and other industries of the filter system, is the best structure of the medium effect filter.
