The unit operates on a 24-volt, two-position motor that is powered in both directions — powered open and powered closed — eliminating reliance on a return spring. A three-wire hookup connects to a common, a power-open leg, and a power-closed leg. Status LEDs on the motor provide visual position feedback: red indicates fully closed and green indicates fully open. These indicators only illuminate after the blade has reached its full open or full closed position, making them a true end-of-travel confirmation rather than a command signal. HVAC technicians and zone-control installers use this damper to regulate airflow in residential and light commercial zoning systems.\u003c\/p\u003e\n\u003cp\u003eThe EURD-6 is sized for 6-inch round ductwork and is suited for air quality and zone control installations where a reliable, visually confirmed two-position damper is required. The powered-open and powered-closed motor design makes it appropriate for applications where a spring-return failure mode is not acceptable. It is installed by licensed HVAC technicians as part of a multi-zone or IAQ control strategy.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePowered open and powered closed motor — no spring return required\u003c\/li\u003e\n  \u003cli\u003e24-volt, two-position motor for compatibility with standard zone control panels\u003c\/li\u003e\n  \u003cli\u003eThree-wire hookup: common, power-open, and power-closed legs\u003c\/li\u003e\n  \u003cli\u003eLED position indicators: red for fully closed, green for fully open\u003c\/li\u003e\n  \u003cli\u003eLEDs activate only at full blade travel — true end-of-travel confirmation\u003c\/li\u003e\n  \u003cli\u003eSingle-blade round construction for 6-inch round duct applications\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 6-inch round duct systems used in residential and light commercial HVAC zone control and air quality 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 handling unit and de-energize the 24-volt control circuit before wiring or positioning the damper. Verify wire connections to the common, power-open, and power-closed terminals match the zone controller wiring diagram before applying power. Confirm LED status indication at startup to validate full blade travel in both directions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: URD Motorized Damper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Positions\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\u003eBlade Type\u003c\/strong\u003e: Single blade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Quality \/ Zone Control\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-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51343995633970,"sku":"EURD-6","price":183.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554843.jpg?v=1782026353","url":"https:\/\/voomisupply.com\/products\/ewc-controls-eurd-6-motorized-round-damper-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
