The Triangle IWS21 Industrial Exhaust Shutter is a heavy-duty single-panel gravity shutter designed for industrial ventilation systems. Built with a welded galvanized steel frame, extruded aluminum blades, and bronze pivot bushings, it offers smooth, low-maintenance operation and long service life in demanding commercial, industrial, and agricultural settings.
When installed on an exterior wall or fan housing, the IWS21 shutter opens automatically with fan airflow and closes when the fan stops, helping reduce backdrafts and unwanted air infiltration. It’s ideal for exhausting hot or contaminated air from warehouses, workshops, barns, and other ventilated spaces.
