The characteristics：
1. High dust removal accuracy: micron filter aperture can completely remove the smoke and dust of more than 10um, and most of the smoke and dust of more than 0.3um can be removed;
2. Filtration area: the filtration surface is wavy, and the filtration area within the same volume is 3-8 times that of the filter bag;
3. Acid and alkali resistance: special ultra-high molecular weight materials, can withstand the long-term corrosion of strong acid and alkali;
4. Service life: good physical performance enables it to be used normally for at least 5-10 years;
5. Low maintenance cost: only dust residue left after blowing and filtering needs to be removed;
