three-ear pleated filter element

The three-ear pleated filter element (also known as a three-claw or chuck filter element) is a high-efficiency air filtration element designed specifically for industrial dust removal systems. It is commonly used to filter fine dust generated in industries such as welding fumes, powder coating, sandblasting, cement, and pharmaceuticals.

Key Features

Easy Installation: The three-ear (three-claw) bayonet design allows for easy installation and removal from either the clean air or dirty air side of the dust collector, without tools.

High-Efficiency Filtration: Typically uses long-fiber polyester filter media with surface treatments such as oil and water repellency, antistatic properties, or PTFE membrane coating, achieving a filtration efficiency of over 99.99% (for particles larger than 0.3 microns).

High Durability: Excellent abrasion resistance and chemical corrosion resistance; the aluminum or galvanized steel top cover and inner core are corrosion-resistant; the robust structure allows for repeated washing and reuse.

Large Filtration Area: The pleated design significantly increases the effective filtration area, ensuring a low and stable pressure drop and improving airflow circulation.

Application Scenarios

This filter element is particularly suitable for the following industrial environments with high dust concentrations:

Powder coating equipment

Shipyards and welding fume treatment

Shot blasting machines and metal processing

Cement and mining industries

Wood processing and pharmaceutical industries
