Pleated(Star) Filter Bags Filter Bags
Pleated filter bags are engineered to upgrade traditional baghouse performance by combining the surface area and rigidity of a cartridge-style element with the dimensional flexibility of a fabric filter. Pleated bags are widely used in cement mills, grain processing facilities, powder coating lines, pharmaceuticals, metalworking, and general industrial dust collection, where fine particulate and high dust-loading conditions require stable airflow and longer service life.
Pleated geometry can offer 100–250% more surface area than a conventional cylindrical bag, improving airflow uniformity and reducing filter loading rate.
The surface filtration mechanism and structured pleat spacing help maintain low ΔP, resulting in reduced fan power and more stable process ventilation.
Unlike felt bags that rub against steel cages, pleated bags have an integrated support core, reducing mechanical wear and extending operating life in abrasive dust conditions.
Dust accumulates predominantly on the external pleat surface; cleaning is more efficient, requiring fewer compressed-air pulses and lowering operating cost.
Using spun-bonded polyester, PTFE membrane, or nano-coated layers, pleated bags excel in capturing very fine particulate such as cement dust, toner powders, pigments, and pharmaceutical powders.

Pleated filter bags are widely used in industries that require high-efficiency fine dust collection within limited space. Their expanded surface area and low pressure drop make them ideal for cement mills, grain and feed processing, powder coating systems, metalworking fumes, pharmaceuticals, food processing, and general industrial dust collection
Highly cohesive powders require stable surface filtration to maintain consistent product quality and dust emissions.
Pleated bags are ideal for mill venting, clinker handling, and silo applications where compact housings demand higher filtration area without enlarging the baghouse.
High efficiency synthetic media options control smoke, metallic aerosols, and fine particulate.
