The working principle of the dust filter mainly relies on the filter element to physically intercept and adsorb dust particles in the air.
The filter element is usually made of materials such as fiber or metal mesh, with different filtration precisions, generally ranging from 1 μm to 78 μm.

When air passes through the filter element, dust particles are intercepted and adsorbed on its surface, thereby achieving air purification.
In addition, some high-efficiency dust filters also adopt electrostatic adsorption technology. By applying an electrostatic field to the filter element, dust particles are adsorbed onto the element under the action of the electric field force, further enhancing the filtration effect.

Application fields:
Dust filters are widely used in chemical, electric power, and building materials industries, particularly in processes involving gas transmission, monitoring, or purification, to ensure gas quality and the normal operation of equipment.
