Product Details
The Flanged Frame models AMD and GMD are heavy-duty motorized volume control dampers featuring a 1-1/2" flanged frame with welded corners for enhanced strength. These dampers include 6" wide blades that are center-pivoted, allowing for a full 90-degree rotation with parallel blade action. Equipped with stainless steel jamb seals, they effectively prevent light, air, and moisture infiltration. Suitable for both exhaust and supply applications, these dampers can be mounted in vertical or horizontal positions, typically in walls or curbs. The AMD model is constructed from extruded aluminum, while the GMD model is made from galvanized steel. Each unit comes standard with an internally mounted, factory-installed 24-240 volt power open/spring close motor with end switches. Additionally, these products are made in the USA.
