1. The selection of high-quality and high-efficiency flame-retardant filter materials, combined with advanced folding technology, makes the filter cartridge have the characteristics of large incombustible filtering area, small pore size, large air permeability, low resistance and high efficiency;

2. The end cover and the inner and outer protective net are made of high-quality galvanized sheet, which has good anti-corrosion and anti-rust performance;

3. The closed-cell rubber seal with low hardness and high strength ensures the air tightness of the filter cartridge;

4. The use of super strong adhesive will not cause degumming and cracking, ensuring the service life of the filter cartridge and the use safety under high load.
