    High temperature resistance Dust Filter Material

    High temperature resistance filter media from Zonel Filtech which is a needle felt filter material series for dust collection. The series is suitable for the operating circumstance with the continuous temperature not exceed 260 degree centigrade and the maximum instant temperature not exceed 280 degree centigrade, during the temperature area, Zonel Filtech can help you to define the most suitable filter material for your dust bag filter houses.

    Zonel Filtech can provide both needle felt filter cloth rolls and ready-made filter bags, the material include:
    Polyimide (P84) needle felt filter cloth and filter bags with various finish treatments;

    When the temperature of the dust air more than 250 degree C and the dust can not be collected through ESP, then as usual we have to reduce the temperature of the dust air and make it possible to be purified through bag type dust collectors, but the investment will increase much when this happen.

    Due to the fiber glass is fragile and PTFE fiber with a higher heat shrinkage and weak cohesion, for meeting the high filter efficiency, both of them need to be laminated with PTFE membrane, which will increase the resistance of the bag filter houses and lower the air/cloth ratio of course, so the polyimide filter cloth (can be P84 filter cloth, PI needle felt, Yilun filter cloth) will become to the first option.

    Polyimide (P84 needle felt filter cloth, PI filter cloth, Yilun needle felt) fiber with the properties of good high temperature resistance, acid resistance and inflammable, the tri-leaves structure of the fiber helps the polyimide needle felt filter cloth with a larger filter surface and with a much higher filter efficiency.
