EcoStream 90 (ES90) wall louvers are designed for heavy commercial and industrial applications. These heavy-duty louvers are designed to withstand the harshest industrial conditions, while still being light enough to easily open and close. This 90° wall louver offers maximum airflow by utilizing a full-opening adjustable blade design. The ES90 has no operating costs and requires little to no maintenance over its life span.
For a 90° louver, similar to the EcoStream 90 but made of extruded aluminum, please see the LVR-ES90-EA.
