Performance and Application

The P312 filter utilizes progressive-density synthetic polyester media designed to capture airborne particulates while maintaining low resistance to airflow. The Monobond™ heat-sealed frame construction provides a continuous bond between the filter media and frame, eliminating weak corners and preventing air bypass. This design ensures structural durability and uniform media support under operational stress. The P312 delivers consistent performance in systems requiring synthetic, moisture-resistant filtration materials.

Usage Notes

Install according to airflow direction indicated on the frame. Inspect during scheduled maintenance intervals and replace when dust accumulation or pressure drop indicates reduced efficiency. The P312 is designed for single-use operation and should not be cleaned or reused. Store flat in a clean, dry environment before installation to maintain frame alignment and media integrity.
