1.With galvanized iron or aluminum alloy as the structure of the outer frame;
2.Each filter bag between a metal strip fixed, increase the strength, and prevent the filter bag in the high wind speed, due to the wind-cut 抆 force and rupture;
3.Each filter bag has six compartments evenly distributed in the bag width, to prevent the filter bag under the wind pressure when excessive expansion, mutual shielding, reduce the effective filtration area and efficiency;
4.Each filter bag Edge is rong by ultrasonic method, which has good air tightness and bonding strength, and does not produce leakage or crack;
5.The use of ultrafine synthetic fibers with special weaving method to avoid the old glass fiber materials may cause discomfort to the human body;
6.Filter material contains electrostatic fiber, sub-micron dust filtration efficiency is particularly good, with high dust capture capacity, high dust load and high permeability, high service life;
7.There are 35%, 45%, 65%, 85%, 95%, 98% that is, G4, F5, F6, F7, F8, F9 Six kinds of efficiency of the bag filter can be selected.
