Description
High-Performance Spunbonded Polyester Media for Pleated Filter Cartridges
Product Overview
Our spunbonded polyester pleated filter media is engineered for industrial dust collector cartridges, delivering a balance of durability, precise filtration, and customizable surface treatments. Designed for challenging dust collection applications such as powder coating, metal grinding, cement processing, and pharmaceutical industries, it ensures stable efficiency, longer lifecycle, and reduced maintenance costs.
With uniform pore distribution, high tensile strength, and excellent abrasion resistance, this media performs reliably even under high dust loads and fluctuating operating environments. Advanced finishing options such as PTFE membrane, anti-static treatment, water & oil repellency, flame retardancy, and nanofiber coatings make it adaptable to both standard and extreme conditions.

Remarks
① Air Permeability measured at ΔP = 200 Pa.
② Filtration Precision refers to the minimum particle size effectively blocked at the initial stage before dust cake formation. In actual use, filter fineness can be improved by lowering air-to-cloth ratio and establishing a stable dust cake.
③ MERV Grade tested according to ASHRAE 52.2 (USA) or EN779 (Europe) standards.
