    Features

    • Excellent steady under high temperature and resistance to acid
    • P84 can operate continuously, under practical and low acid working conditions, at temperatures up to 500°F(260 °C).
    • High filtration efficiency, high tensile strength.
    • The complex cross sectional shapes create 30-90% more collection surface area when compared to round or oval shaped fibers.
    • Low back washing pressure, maximun flexibility
    • The unique tri-lobal fiber structure of P84 provides customers with high efficiency filtration, low pressure drop, and reduced cleaning energy.
    • Excellent dust cake release
    • P84 has irregular, tri-lobal fibers that provide better collection efficiencies and enhanced dust cake release properties.


    How to make dust filter needled felt

    Needled felt, called punched filter cloths too, is a kind of nonwoven fabric, which is used for industry dust filtration. Needled punched felt is made of fiber and scrim, three layers construction with scrim inside. The first step is fiber feeding, and carding, needling, heat treatment, singeing, calender, impregnation, lamination (memberance) , inspection and pack, and then ship out.
