FMS Needle Punched Felt
Diaphragm

Detail:

FMS compound Needle Punched Felt
FMS is a good high temperature resistance filter fabrics, this fabrics mainly made by 5.5 micron diameter glass fiber blend with P84 (polyimide), aramid(Nomex), PPS (ryton) fiber, with the three dimensional cellular structure, low air resistance, especial blend with P84 which with leaf style fiber, can increase the filter surface (80%), so easy to collect the dust, increase the fiber cohesion, can accept the high wind speed (50% higher about 1~1.4m/min), and also with the properties of abrasion resistance. This kind of fabrics widely used in metallurgical plant, chemical plant, coal fired boiler, incinerator, cement plant for dust collector or smoke filtration in high temperature circumstance.
