Built for 8-inch round duct applications, this damper provides manual airflow regulation within a trunk-and-branch or radial duct layout. The all-metal construction supports durability in both supply and return air configurations. HVAC technicians and sheet metal installers working on residential and light commercial forced-air systems will find this assembly compatible with standard 8-inch round duct fittings, including the 1500-series collar.\u003c\/p\u003e\u003cp\u003eThis damper assembly is intended for installation in 8-inch round ductwork, specifically noted for use with the 8-inch 1500-series metal duct system. It is suited for residential forced-air heating and cooling applications where zone control or balancing is required at individual branch runs. The round profile integrates with standard snap-lock and slip-fit round duct connections common in residential new construction and retrofit HVAC work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-inch round duct damper assembly for airflow balancing and zone control\u003c\/li\u003e\n\u003cli\u003eAll-metal construction for durability in forced-air duct systems\u003c\/li\u003e\n\u003cli\u003eDesigned for compatibility with 8-inch 1500-series round metal duct collars\u003c\/li\u003e\n\u003cli\u003eManual damper operation for straightforward airflow adjustment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 8-inch 1500-series round metal duct systems.

Shut down the air handling unit and confirm the system is de-energized before cutting into or modifying ductwork. Secure all connections with sheet metal screws and approved duct sealant per local mechanical code requirements. Do not restrict damper blade travel during installation, as partial obstruction can cause airflow noise and pressure imbalance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembly Type\u003c\/strong\u003e: Round Damper Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HART COOLEY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: r22 08 brn\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51233739309362,"sku":"R22 08 BRN","price":26.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307629055.jpg?v=1780107951","url":"https:\/\/voomisupply.com\/products\/hart-cooley-r22-08-brn-round-damper-assembly-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
