◆ 中效空气过滤器说明:
中效空气过滤器主要阻挡5um以上的灰尘颗粒,具有过滤面积大,容尘量大,低阻力,能重复清洗使用等优点。
◆ 中效空气过滤器应用:
被广泛应用于中央空调通风系统,制药、医院、电子、食品等工业净化中,还可作为高效过滤器的前端过滤,以减少高效空气过滤器的负荷。延长其使用寿命。由于中效袋式空气过滤器的迎风面积大,因此它的容尘量大,风速低,被认为目前最好的过滤器结构
◆ 中效空气过滤器结构:
中效空气过滤器采用新型复合无纺布或微细玻璃纤维及进口合成纤维外加被覆补强成型滤料,袋式造型,配以各种金属外框(镀锌板、铝板、铝合金型材)
◆ 中效空气过滤器滤料:
中效空气过滤器一般所用的滤材为三种,复合无纺布,进口合成纤维和玻璃纤维。
◆ 中效空气过滤器过滤知识:
中效空气过滤器是一般通风空调系统必不可少的。它是过滤的主力军。做成中效袋式空气过滤器主要是为了满足大风量,低阻力的要求。严格的讲,中效空气过滤器的前端还要有一层预过滤装置,一般使用一次性纸框或金属框板式过滤器。但是国内的一些用户在前端纸框过滤器达到寿命之后就不在更换而直接用中效过滤器作第一级过滤,造成中效空气过滤器使用环境恶劣,寿命缩短,不能达到厂家设计要求。这种情况应该尽量避免,虽然增加一道预过滤一次采购成本增加了,但是可以延长中效空气过滤器的更换周期,长远来讲总的维护成本反而降低了。
Medium-efficiency bag filterDetails:
Application:
Bag filters are extensively used in the ventilation system of the center air condition and the purification of pharmacy industry ,hospital, electron industry, and food industry etc. additionally, they can be in the front edn filtration of the high-efficientlyair filter to reduce the loads and prolong their sevince life. Bag filters have dust holding capacity and low wind speed because of their big windward area,therefore,they are regarded as the best-efficiency filter structure up to the present.
Structure:
They use new-type complex nonwoven or imported minute glass fiber and imported synthetic fiber and covered with reinforcing and molding filter materials. They have bag-shapped moulds and are equipped with all kinds of meter outside frame(galvanizing plate,iron plate,the alumium alloy,etc)
Filter materials: Generally ,there are 3 kinds of filter material used,namely ,complex nonwoves,synthetic fiber,and glass fiber.
