Built with a galvanized steel frame that is 2 inches deep and aluminum louver blades, this damper prevents reverse airflow when the exhaust fan is not running. Outer dimensions measure 8 inches x 8 inches. Spring-assisted operation allows the blades to open quickly when airflow is present, and a felt seal along the leading edge of each louver provides quiet closing. Licensed HVAC technicians and commercial ventilation contractors install this type of component as part of rooftop exhaust assemblies.\u003c\/p\u003e\u003cp\u003eThe 411008 is rated for horizontal-mount exhaust installations and is compatible with the size 7 CWD Exhauster. It is suited for commercial and light industrial ventilation systems where backdraft protection is required at the point of roof discharge. An optional motor kit, part number 411611, is available for motorized operation. This damper is not approved for grease exhaust applications and must not be installed in explosive or flammable atmospheres, including areas where flammable airflows are present.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGalvanized steel frame, 2 inches deep, for corrosion resistance in rooftop environments\u003c\/li\u003e\n\u003cli\u003eAluminum louver blades reduce weight and resist oxidation\u003c\/li\u003e\n\u003cli\u003eSpring-assisted blade operation for fast opening response\u003c\/li\u003e\n\u003cli\u003eFelt seal on louver leading edges for quiet, low-impact closing\u003c\/li\u003e\n\u003cli\u003eCompatible with optional motor kit 411611 for motorized damper control\u003c\/li\u003e\n\u003cli\u003eNot approved for grease exhaust or flammable and explosive atmospheres\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the size 7 CWD Roof Exhauster.
