The filter itself is an engineering marvel. Our filter elements are covered with a layer of microfiber material in addition to the normal filter material. This additional layer greatly improves filtration, allowing the dust collector to capture particles as small as 0.5 microns. Our cartridge dust collectors have a 99.9% collection capacity for particles over 0.5 microns, ensuring that even the tiniest particles are effectively captured.Our cartridge dust collector not only has unparalleled efficiency, but also is very energy-saving. Due to the design of the filter cartridge, the dust only stays on the surface of the microfiber layer, and the filtering resistance is greatly reduced. The reduction in drag results in significant power savings, with our dust collectors consuming over 30% less energy than conventional models. The energy savings are undeniable, providing environmental and cost benefits.It is very simple and hassle-free to operate the cartridge dust collector. The pulse back blowing dust cleaning device makes cleaning and maintenance easy. The dust collector continues to operate efficiently, ensuring your work environment remains clean and free of harmful airborne particles.
