Polyester needle punched felt filter bags
The needle felt filter bag has the advantages of high space, high permeability, high dust collection efficiency and long service life. Its temperature resistance grade is moderate, it can reach 150 degrees centigrade instantaneously, it is moderate in acid and alkali resistance, and has excellent wear resistance. The needle punched felt filter bag (dusting bag) is the key part in the operation of the bag type dust collector. The fabric and design of the needled felt filter bag try to pursue high efficiency filtration, easy to peel off dust and durable effect.
