Model EVS-745

Extruded Aluminum Sand Louver
7" Deep - 45 Degree Vertical Blade

The EVS-745 is designed and tested for protection against wind-driven sand. The EVS-745 offers greater free area and lower pressure loss than most other sand-trap louvers, making it well suited for situations requiring high rates of airflow through the louver. The EVS-745 incorporates vertical blades and is available in a wide array of anodized or painted finishes including custom color matching.
