Polyester Dust Collector Cartridge Filter – Large Filtration Area & Low Resistance

The pleated filter media of polyester dust collector cartridge filter are made from polyester fiber through a thermally bonded spunbond non-woven process. This design significantly increases the filtration area, effectively reduces operating resistance, and improves dust removal efficiency (with a filtration efficiency of over 99.5% for particles ≥ 0.3 μm).

It is suitable for most dust collection systems operating at ambient temperatures ( ≤ 120 °C), and is widely used in industries such as metal processing, welding and grinding, woodworking, grain, construction materials, and pharmaceuticals.

Features

Excellent filtration performance. Base filtration efficiency exceeds 99.5%, and with membrane treatment, filtration efficiency is further enhanced (> 99.9%).
High mechanical strength. Polyester fiber material offers exceptional toughness and high tensile strength at break, making it resistant to deformation and capable of withstanding frequent pulse cleaning.
Reusable. The cartridge filter can be washed with water or air, facilitating maintenance, extending service life, and reducing operating costs.
Multiple functional treatments. Custom options such as ePTFE membrane, anti-static, and flame-retardant treatments are available to meet different dust control requirements.
Low operating resistance & energy-saving. With a low pressure drop, the cartridge filter contributes to energy-efficient operation and making it suitable for continuous operation.

Structure

Gasket: Prevents gas leakage and secures the filter cartridge in place during pulse cleaning to avoids vibration-induced displacement.
Top end cap: Provides structural support, sealing, and installation positioning. Available in various styles, sizes, and materials to match different dust collector models and operating conditions.
Metal outer guard mesh / band: Constructed from galvanized or stainless steel mesh or binding strap to support the filter media, reinforce the cartridge filter, and prevent deformation.
Pleated filter media: Filter media is processed into a large-area, corrugated form with specific pleat pitch and height.
Metal inner protective mesh: Made from galvanized or stainless steel mesh to support the filter media and enhance resistance to negative pressure.
Bottom end cap: Available in closed or perforated designs, with different end cap styles, sizes, and materials according to customer requirements.
