1. Working principle of dust filter cartridges

The dust filter cartridge mainly removes pollutants from the air by physical filtration. It usually consists of filter material, support structure and shell. When air containing dust and particulate matter passes through the dust filter cartridge, the filter material intercepts these pollutants and allows clean air to be discharged through the filter cartridge.

The filter material is the core part of the dust filter cartridge. Common filter materials include paper, polyester fiber, glass fiber, etc. These materials have different filtering properties and characteristics, and can be selected according to different application requirements. For example, paper filter cartridges are suitable for general industrial dust filtration, polyester fiber filter cartridges have good moisture resistance and wear resistance, and glass fiber filter cartridges are suitable for high temperature, high humidity and corrosive environments.

The support structure is mainly used to maintain the shape and stability of the filter material and prevent the filter material from deforming or breaking under the action of airflow. The outer shell protects the filter material and the supporting structure, and is also convenient for installing and replacing the filter cartridge.
