This  bag filter type dust collector is new improved high-efficiency pulse bag filter on the basis of MC type - I. In order to further improve the MC - type ? pulse bag dust collector, We modified into MC - type ?.This MC-type II has the same purification efficiency as MC - ? type with the ability to process large quantity of gas  , stable performance, convenient operation and long life of filter bag, small maintenance workload etc.  We also modify the structure and the pulse valve to solve the outdoor setting and the problem of low pressure of compressed air. It is widely used in dust collecting and removing in machinery, metallurgy, rubber, flour, chemical, pharmaceutical, carbon, building materials, mining and other industries.
