12" x 12" x 1" Disposable Synthetic Warm Air Panel Filter, Merv 4

Details

Model: P312-12X12X1LR Purolator WARM AIR FILTER
Size: 12" x 12" x 1"
Part No.: 2021994

The Purolator P312 series synthetic disposable panel filters are engineered for performance and reliability in HVAC systems serving residential, commercial, and light industrial environments. Designed for applications specifying synthetic media, the P312 provides consistent filtration efficiency, high structural integrity, and compatibility with variable system conditions.

Technical Specifications

• Media: Non-woven polyester fibers bonded into an interlocking matrix, forming a gradient-density structure optimized for maximum dust-holding capacity and minimal resistance to airflow.
• Frame Construction: Single-piece Monobond pinch frame fabricated from post-consumer recycled materials. The frame is thermally sealed to the media under heat and pressure, ensuring a continuous bond around the entire perimeter to prevent air bypass and weak corners.
• Adhesive/Binder: High tensile strength binder reinforces media-to-frame adhesion, maintaining bond integrity under fluctuating temperature and humidity conditions.
• Operating Range: Suitable for HVAC systems with variable air volume, temperature, and humidity environments where synthetic media filtration is required.
• Performance Characteristics: Optimized dust loading and resistance control, ensuring sustained airflow and filtration efficiency throughout service intervals.
• Applications: Designed for installation in air handling systems across commercial facilities, institutional settings, and light manufacturing operations.

Summary

The Purolator P312-12X12X1LR synthetic panel filter combines a heat-sealed monobond frame with durable polyester media to deliver consistent filtration performance under demanding conditions. Engineered for professional applications, it provides stable airflow, superior dust retention, and structural durability across a wide range of HVAC environments.
