What key factors affect dust collector filtration efficiency?

Five main factors: 1) Cartridge material and precision (PTFE membrane, polyester fiber and other media differ greatly in filtration precision); 2) Dust characteristics (particle size, humidity, stickiness and concentration); 3) Equipment air velocity (excessive filtration velocity lets dust penetrate the media and lowers efficiency); 4) Cleaning system condition (pulse pressure and injection frequency directly affect how well dust is removed from cartridges); 5) Equipment sealing (housing air leakage causes dust-laden airflow to short-circuit and reduces filtration performance).
