滤料为改性聚酯纤维按纤维粗细和密度不同，以非织物方式、多向性、渐层性、轧针法制成
组织结构均匀，在风压及承重压力下，不会压缩变形，仍能保持高性能。
背覆网，加强定型，有效引导空气均匀层流。
结构紧凑，在承受风压时，毛细纤维不易脱落，容尘量高、透气性好，压损低。
耐燃性达到美国UL-900 Class 2 标准，长期耐温达到90℃
符合EN779:2012标准
The filter material is modified polyester fiber made by non-woven, multidirectional, gradient and needle rolling according to the thickness and density of the fiber.
The uniform structure could help it under wind pressure and load-bearing pressure without deformation and could keep high performance.
Back cover the mesh, strengthen the shaping, and effectively guide the uniform laminar flow of air.
The structure is compact. When withstand wind pressure, capillary fibers are not easy to fall off, high dust tolerance,good breathability and low pressure loss.
Flammability meets the U.S. UL-900 Class 2 standard and 90°C temperature resistance.
Meet EN779:2012.
