The environmentally friendly dust collector utilizes surface filtration technology, employing pleated filter cartridges (made of polyester fiber and a film-coated material) as filter elements. As dust-laden air flows through the filter cartridges, dust is trapped on the filter surface, and clean air is discharged through the outlet. Its compact structure comprises an air inlet, filter cartridge assembly, a cleaning system (primarily pulse jet), an ash hopper, and a control system. It is suitable for handling low- to medium-concentration dry dust with a particle size ≥0.3μm.
