The dust collector is a reverse-blowing external filter bag dust collector structure, featuring both cartridge and bag filter styles. It is suitable for purifying or recovering fine and medium-sized dry dust particles from dust-laden gases. This machine boasts stable operation, high air handling capacity, long filter bag lifespan, and simple maintenance. It can be widely used in industries such as metallurgy, machinery, casting, chemicals, cement, construction, and mining. It plays a significant role in preventing air pollution, protecting the environment, and eliminating smoke and dust, with a dust removal efficiency generally exceeding 99%. When used in conjunction with a cyclone dust collector, the performance is even better.
