Standard Hot Gas Cleaning Filter with Double Dust Removal Capacity

Standard hot gas cleaning filter is a kind of filter bag made of metal powder by sintering into flexible metal powder sintered filter sheet, then cut into suitable size to fit for the cage bone, and welded to the cage bone. Its filtration efficiency is 2 times of the bag filter under the same working conditions and resistance. A metal ring is welded at the opening of the flexible metal membrane for installation and positioning. Hexagonal metal gasket is used for the sealing of the metal ring and the installation plate to prevent the leakage of dust removal gas.
