Operating on 24 volts AC at 60 Hz, it draws 6 watts and carries a 12 VA rating, making it compatible with standard low-voltage zone control boards and thermostats. The rectangular blade assembly measures 8 inches by 8 inches, fitting standard square duct openings of that size. Licensed HVAC technicians install this damper to regulate airflow between zones, improving system efficiency and occupant comfort. It is a direct-wired, motorized unit actuated by a 24 VAC signal from a zone controller.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for forced-air zoning applications in residential and light commercial buildings. It fits into 8-inch by 8-inch rectangular duct sections and is actuated by a standard 24 VAC zone control signal. Typical installations include multi-zone split systems, air handler duct branches, and retrofit zoning projects where independent room or area temperature control is required. The 60 Hz operating frequency confirms compatibility with standard North American electrical systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24 VAC motorized actuation compatible with standard low-voltage zone controllers\u003c\/li\u003e\n  \u003cli\u003eRectangular blade design sized for 8 x 8 inch duct openings\u003c\/li\u003e\n  \u003cli\u003e6-watt power draw with 12 VA rating keeps transformer load low\u003c\/li\u003e\n  \u003cli\u003e60 Hz rated for standard North American HVAC electrical systems\u003c\/li\u003e\n  \u003cli\u003eDesigned for multi-zone forced-air duct applications in residential and light commercial settings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation motorized damper for 8 x 8 inch rectangular duct openings in 24 VAC forced-air zone control systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Disconnect power to the air handler and zone control panel before wiring or mounting the damper. The low-voltage wiring connections must comply with NEC requirements for Class 2 circuits. Verify that the zone controller transformer VA capacity can support the added 12 VA load before completing the installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 24 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Rating\u003c\/strong\u003e: 6 watts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVA Rating\u003c\/strong\u003e: 12 VA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency Rating\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RESEARCH PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6721\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RESEARCH PRODUCTS","offers":[{"title":"Default Title","offer_id":51138540339506,"sku":"6721","price":162.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532996.jpg?v=1778258863","url":"https:\/\/voomisupply.com\/products\/research-products-6721-motorized-damper-8x8-in-24vac","provider":"Voomi Supply","version":"1.0","type":"link"}
