Technical Specifications

• Media: Progressive density polyester fibers bonded into an interlocking matrix that captures airborne particulates while maintaining uniform airflow and minimizing static pressure increase.
• Frame Construction: One-piece Monobond pinch frame manufactured from post-consumer recycled materials. The frame is thermally sealed to the media, producing a continuous bond around the perimeter to eliminate corner separation and air bypass.
• Adhesive/Binder: High tensile strength binder ensures media-to-frame bond integrity under varying temperature and humidity ranges.
• Operating Conditions: Suitable for HVAC systems operating under variable air volume and temperature conditions where synthetic media is specified.
• Performance Characteristics: Engineered to optimize dust-holding capacity and resist surface loading, extending operational intervals while maintaining consistent air delivery.
• Applications: Designed for professional installation in air handling systems for office buildings, light manufacturing, institutional, and commercial environments.

Summary

The Purolator P312-18X25X1 synthetic panel filter provides dependable performance through precision-engineered polyester media and a durable monobond frame.
