Needle Felt of water repellence, oil repellence anti static
In the filtration process of the filter bag, the dust is very easy to adhere to the bag if the content of moisture and oil in the gas is high. This is helpful to the dust collection, however at the same time makes the clean difficult. Moreover, the dust will jam the finstra of the bag and corrupt the material which increases the flow resistance. Suita design the needle felt to meet your requiremnt. The three resistance of three resistant filter felt means water repellence, oil repellence and anti static , it is said on the base of anti-static filterfelt add to the properties of water repellence and oil repellence. It is used in the occasion of high humidity, such as high stove jet coal powder of ironsteal factory, cement , conveying coal system of power factories.
