Product Overview
Pleated Synthetic Panel Air Filter Media is a high-performance coarse filtration material engineered specifically for panel-type filter assemblies in commercial HVAC and AHU systems. This media utilizes a unique thermal bonding process that fuses bicomponent synthetic fibers into a dimensionally stable non-woven sheet, which is then mechanically pleated to multiply its effective filtration area. The pleated geometry significantly reduces face velocity across the media, allowing the structure to capture coarse contaminants more efficiently while maintaining exceptionally low resistance to airflow.
Designed to meet G2 through G4 efficiency classifications per EN 779 standards, this media serves as the frontline defense in multi-stage filtration trains, protecting downstream cooling coils, heating elements, and higher-grade final filters from premature loading. Its all-synthetic composition ensures consistent mechanical performance across fluctuating temperature and humidity conditions commonly encountered in air handling applications.

Product Features
Pleated Synthetic Panel Air Filter Media combines structural rigidity with high dust storage capacity, ensuring dependable G2–G4 filtration performance while minimizing maintenance frequency in HVAC pre-filtration applications.
Mechanically Pleated Configuration: The precise pleating process increases effective media surface area by up to 300% compared to flat sheets, enabling higher dust loading without compromising airflow. This geometric advantage reduces pressure drop progression over time, extending filter change intervals and lowering labor costs.
Thermally Bonded Fiber Matrix: Bicomponent fibers are fused at intersection points without chemical binders, creating a resilient open-cell structure that maintains pleat integrity under varying velocity and pressure conditions. This construction eliminates fiber shedding and prevents media collapse.
Excellent Dust Holding Capacity: The coarse synthetic panel filter material exhibits dust holding performance exceeding 350 g/m² at G4 level under standardized test conditions, effectively capturing airborne particles ranging from 3 to 10 microns including sand, textile fibers, and plant debris.
Moisture & Chemical Resistance: The polyester-based synthetic substrate resists degradation from occasional moisture carryover and withstands exposure to mild chemical fumes commonly present in industrial ventilation environments.
Product Applications
Pleated Synthetic Panel Air Filter Media serves as the primary filtration layer in diverse commercial and industrial ventilation systems, where effective G2–G4 pre-filtration is essential for protecting downstream equipment and maintaining occupant comfort.
Office Building AHU Intake Plenums: Captures outdoor airborne contaminants such as atmospheric dust, pollen, and insect debris before they enter the building's ductwork, preserving indoor air quality and reducing cleaning frequency.
Retail Mall Ventilation Systems: The G4 grade pleated air filter sheet effectively removes lint fibers and textile dust generated by occupied spaces, preventing coil fouling and ensuring consistent thermal performance.
Industrial Manufacturing Facilities: Filters coarse particulate generated from material handling operations, protecting sensitive production equipment and maintaining compliance with workplace air quality standards.
Hospital HVAC Pre-Filtration: Installed in the first stage of hospital air handling units, this media reduces bioload on downstream medium and HEPA filters, extending their operational lifespan.
Data Center Cooling Systems: Pre-filters outdoor air entering computer room air handlers, preventing abrasive particles from reaching expensive cooling coils and server fans.
