Product Details
Flanged frame models AMD and GMD are heavy-duty motorized volume control dampers featuring a 1-1/2" flanged frame with welded corners for added strength. The 6" wide blades are center-pivoted, allowing a full 90-degree rotation with parallel blade action. Stainless steel jamb seals help to keep out light, air, and moisture. These dampers are suitable for exhaust or supply applications and can be mounted vertically or horizontally, typically in walls or curbs. They are available in extruded aluminum (AMD) or galvanized steel (GMD) and include a standard internally mounted, factory-installed 24-240 volt power open / spring close motor with end switches. The product is made in the USA.
