The unit ships with a two-position, 24-volt motor that is powered in both directions — powered open and powered closed — eliminating reliance on a spring return. A 3-wire connection (common, power-open, power-closed) gives the installing technician straightforward wiring to a zone controller or relay board. LED indicators confirm blade position: red signals fully closed, green signals fully open. These indicators illuminate only after the blade reaches its full travel position, making them a reliable status check rather than a simple motor-power indicator.\u003c\/p\u003e\n\u003cp\u003eThe EURD-8 is suited for residential and light commercial HVAC zoning applications where positive damper control is required in 8-inch round ductwork. It is a fit for air quality and zoning systems where the zone controller or damper panel requires a powered-open, powered-closed actuator rather than a spring-return type. HVAC technicians and sheet metal installers typically specify this damper in supply or bypass duct runs tied to multi-zone forced-air systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-position 24-volt motor — powered open and powered closed with no spring-return dependency\u003c\/li\u003e\n  \u003cli\u003e3-wire hookup: common, power-open leg, and power-closed leg for straightforward zone controller integration\u003c\/li\u003e\n  \u003cli\u003eRed and green LED indicators confirm full blade travel — red for closed, green for open\u003c\/li\u003e\n  \u003cli\u003eLED indicators serve as a failsafe: they do not illuminate until the blade reaches full open or full closed position\u003c\/li\u003e\n  \u003cli\u003eSingle-blade round design sized for 8-inch round duct\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style motorized damper for use with 24-volt zone control systems requiring a powered-open, powered-closed actuator in 8-inch round duct applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with low-voltage zoning systems. Disconnect power to the air handler and zone controller before wiring the damper motor. Confirm the zone control panel or relay board supports a powered-open, powered-closed actuator before connecting the 3-wire harness. Follow all applicable mechanical and electrical codes, including NEC low-voltage wiring requirements, during installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Motorized Round Damper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Operation\u003c\/strong\u003e: Two-position, powered open and powered closed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWires to Motor\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Quality \/ HVAC Zoning\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: EWC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EURD-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51346234900786,"sku":"EURD-8","price":187.02,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554837.jpg?v=1782074781","url":"https:\/\/voomisupply.com\/products\/ewc-controls-eurd-8-motorized-round-damper-8-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
