The F8 medium efficiency filter bag is made of high-performance electrostatic filter material, and the edges of each F8 medium efficiency filter bag are fused by ultrasonic method, which has good air tightness and bonding strength.

Each F8 medium efficiency filter bag has six non-woven fabric separators that are evenly distributed across the bag width through ultrasonic bonding, so as not to affect the filtration efficiency due to air leakage or rupture caused by high wind pressure. In addition to having a uniform wind effect, the main function of these separators is to control the filter bag from excessive expansion and mutual shielding when subjected to wind pressure, thereby reducing the effective filtration area and effectiveness. There is no danger of old-fashioned glass fiber breakage and discomfort to humans, no conditions for microbial growth, and a long service life, with a higher operating temperature of up to 80 ℃
