The Return Grille Filter provides a high efficiency, long life alternative to a 1" filter. Our patented design, unique to the industry, captures a significant amount of the airborne particles, in the air that circulates through the filter.
FEATURES & BENEFITS
• Mounts in most return filter grilles. • Pleated for greater media capacity. • Low pressure drop provides a comfortable air flow. • Maintains equipment efficiency longer than standard filters. • Dimensions (in.): 14 in. x 20 in. x 3 in. • Maximum Airflow Capacity (cfm): 750 cfm • Maximum Airflow Capacity (m³/hr): 1270 m³/hr • Efficiency Standard: Efficiency ratings are based on American Society of Heating, Refrigerating and Air-Conditioning Engineers Standard 52.2-1999.,Efficiency ranges are defined for small particles, E1=0.3 to 1.0 microns; medium particles, E2=1.0 to 3.0 microns; and large part • Fractional Efficiency: E1=31%, E2=61%, E3=86% • Minimum Efficiency Reporting Value (Media Filters Only): 10 • Static Pressure Drop (in. w.c.): 0.12 at 300FPM
