    Product Description :

    Aramid Needle Punched Filter Felt 

    In the bags filters industry, the bags always are called hearts. The material of bags will decide what types of gas the filters can deal with. Under the normal working temperature, it only requests the bags to stand for the temperature under 150. The material of polyester, polypropylene, polyamide, etc. Can be competent. Under the high working temperature, such as Chemical and carbon black (silica arogel) plants off-gases, blast furnace plant gas, cement plant shaft kiln off-gas, calcium carbide plants shaft kiln off-gas, casting and steel plant off-gas, bituminous concrete and mixes pitch exhaust gas, fire-resistant brick kiln exhaust gas, coking exhaust gas etc., it requests the material can stand for high temperature. First, because the limitation of specific resistance, the electric dust collectors are not suitable, the bags are the only choice. Second, the cost will be very high or because of the space limitation, the temperature is very hard to be lowered to under 150. Third, because of composition of sulfur in the dust, there will be acid dew point. Therefore, the filtration has to be operated at the temperature above the acid dew point. It requests one type of chemical fiber which can stand for high temperature. We select the Nomex fiber of Du pont. Adopting the international advanced standard, we produce high-temperature needle punched felt
