Product advantages
Filtration Efficiency Innovation
With the deeply customized surface treatment process, a triple synergistic effect of high electrostatic adsorption, low operation resistance and easy dust stripping is achieved. Based on the intelligent matching of coating solutions according to the working condition parameters, the filtration accuracy and ash cleaning efficiency are precisely empowered to be improved.
Long-term Protection
Through the optimized design of fluid mechanics, a low-pressure differential operation system is constructed. Combined with the anti-hydrolysis composite fiber substrate, it ensures that the filter bag can achieve an ultra-long service cycle of ≥ 48 months under the continuous low-resistance state. It has passed the international standard test and certification, and its durability is leading the industry level.
Precise Weaving
The innovative multi-element needle combination technology is adopted, and the gradient density needle arrangement process is used to intelligently adjust the needle frequency. Through the three-dimensional cross-puncture process, the deep infiltration and electromagnetic heating system, the nano-coating is realized. The filtration accuracy reaches 2μm, the filtration efficiency is 99.998%, and the dust stripping rate is > 80%.
