Pocket Type Pre Filters are designed for high dust-holding capacity and consistent airflow in commercial and industrial HVAC systems. Their multi-pocket construction increases filtration surface area, providing longer service life and reducing maintenance frequency. These filters effectively capture larger airborne particles such as dust, lint, and pollen, protecting downstream fine filters and critical equipment from contamination.

Made from synthetic or glass fiber media with stitched or ultrasonic-sealed pockets, they maintain shape even under high air velocities. Rigid galvanized steel or aluminum frames provide durability and stability. Suitable for variable air volume systems, these filters deliver low resistance, high performance, and reliable indoor air quality.
