Operating on 24 volts with a synchronous motor and a 2-wire electrical connection, it mounts at the bottom of the duct section using a bottom-mount comfort configuration. The galvanized steel construction resists corrosion in typical ductwork environments. At 8 inches high by 20 inches wide, this damper suits a range of trunk and branch duct applications. Licensed HVAC technicians install this type of component as part of multi-zone forced-air systems where individual space temperature control is required.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for residential zoning projects and light commercial HVAC applications where rectangular duct dampers are specified. The bottom-mount design accommodates installations where access or duct geometry requires mounting from the lower face of the duct. Its 24-volt synchronous motor integrates with standard low-voltage zone control boards and thermostats commonly found in residential and small commercial zoning systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24-volt synchronous motor compatible with standard low-voltage zoning controls\u003c\/li\u003e\n  \u003cli\u003e2-wire electrical connection simplifies field wiring\u003c\/li\u003e\n  \u003cli\u003eRectangular form factor at 8 inches high by 20 inches wide\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction for corrosion resistance in ductwork\u003c\/li\u003e\n  \u003cli\u003eBottom-mount comfort configuration for flexible installation positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for rectangular duct zoning systems in residential and light commercial forced-air HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Shut down the air handler and de-energize the low-voltage control circuit before installing or replacing a zone damper. Verify duct dimensions match the damper size before mounting, and confirm the zone controller supports a 2-wire synchronous motor configuration. Follow local mechanical codes and manufacturer wiring diagrams when connecting to the zone control board.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: Synchronous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElectrical Connections\u003c\/strong\u003e: 2-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Bottom Mount Comfort\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: 6817\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RESEARCH PRODUCTS","offers":[{"title":"Default Title","offer_id":51268862378290,"sku":"6817","price":198.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308911916.jpg?v=1780707933","url":"https:\/\/voomisupply.com\/products\/research-products-6817-zone-damper-8x20-in-24v-synchronous","provider":"Voomi Supply","version":"1.0","type":"link"}
