FNS®NeedleFelt
FNS®needle felt is with Hotian own brand.FNS®series filter material is produced under the principle of “ Try every effort to serve the environment” . FNS®needle punched felt is constructed by several kinds high temperature resistant fibers together. After needle punching, it shapes into three-dimensional high temperature resistant filter material. Compared with glass fiber filter material, it has more obvious advantages such as abrasion resistance and anti-pleat. So FNS® needle felt can bear high filtering burden, and can reach filtering speed 1.5m/min or higher. FNS® needle felt can avoid chemical filter media elongating, distortion, low service temperature, weak abrasion resistance etc disadvantages. Furthermore,it has stable dimension, good tension, and competitive price.
