Features: 1, the filtration efficiency: As the microporous film has a unique cross-porous characteristics, good on the ultra-fine dust filter performance, filtration efficiency of 99.99%, to achieve near-zero emissions. 2, the running resistance is low: the film surface is extremely smooth, dust stripping performance is very good, even if the fine dust will not wet adhesion, the filter is always running at low resistance. 3, the filtering speed: As the resistance low and stable, an increase of gas flow, improve dust collection capacity. 4, wide application: micro-membrane complex with a variety of fabric with acid and alkali, high temperature, resistant to moisture, dust is easy to strip the performance for various tasks Dust and flue gas purification.
