The specially designed filter media not only has good air permeability, but also increases the effective filtering area, with long service life and high dust removal efficiency.

The filter element is automatically cleaned without stopping the main engine and other operations. When the saturation resistance on the surface of the filter cartridge reaches a certain allowable value, the automatic cleaning function is turned on, and each filter cartridge is cleaned in turn during the working process of the main engine to ensure that the dust collector is always in a good working state.
