P84 dust collector filter bag

P84(polyimide) dust collector filter bag.

DWD group chooses INSPEC FIBERS polyimide fiber produced by Austria LENZING company. With world-class fabric technical guidance of foreign professional companies, we are one of the manufacturer of P-84 high temperature resistant filter material in China.

P-84 filter has three notable features as bellows:
1, Significant temperature resistance
The operating temperature withstanding 260 centigrade, and it has a safe space to deal with outages and accidents.
2. Good anti chemical properties
The filtration value of P84 filter bag for acid waste gas and alkaline dust has been confirmed in the waste incineration operation in the past decade.
3, Low reverse pressure and efficiency of high projectile desliming cake
The characteristics of P84 are remarkable due to the fineness of fiber itself, and because of irregular fiber cross section, which increases the fiber surface area to the maximum and provides many tiny pores to make surface filtration better than deep filtration. Dust only stays on the surface of filter felt and can not penetrate into filter media, so the reverse washing pressure is small, and the cake release efficiency is significantly improved, which has excellent collection efficiency and low working pressure.

It has long been used in asphalt plants, cement plants, waste incinerators, liquid boilers, coal fired boilers and so on.
