Operating on 24 volts AC at 1.5 VA, it uses a 3-wire power open\/power close actuator configuration, giving the zone controller positive damper position in both directions. Rated at 160 CFM, it regulates conditioned airflow within ductwork when paired with a thermostat-based zone control panel. Licensed HVAC technicians install this damper as part of a multi-zone forced-air system to direct heating or cooling to individual zones independently.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for residential forced-air zoning applications where individual room or zone temperature control is required. The round 7-inch body fits standard round ductwork of the same diameter. The 3-wire, power close\/open design is compatible with most residential zone control panels that provide a dedicated close signal, ensuring the blade moves to a fully closed or fully open position on command rather than relying on spring return.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-inch round body sized for standard round duct installations\u003c\/li\u003e\n  \u003cli\u003ePower open and power close (3-wire) actuation for positive blade positioning\u003c\/li\u003e\n  \u003cli\u003e24 volts AC, 1.5 VA low-voltage control circuit\u003c\/li\u003e\n  \u003cli\u003e160 CFM airflow rating\u003c\/li\u003e\n  \u003cli\u003eCompatible with thermostat-driven zone control systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement zone damper for 7-inch round duct thermostat zoning systems requiring a 3-wire, 24-volt power open\/power close actuator.\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 zone control panel before wiring or mounting the damper. The 3-wire harness must be connected per the zone control panel manufacturer wiring diagram. Ensure the damper blade rotates freely and the duct collar is sealed with approved tape or mastic after installation to prevent air leakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Zone Damper, Round, Power Close\/Open\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 7 inches round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 24 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Draw\u003c\/strong\u003e: 1.5 VA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow Rating\u003c\/strong\u003e: 160 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiring\u003c\/strong\u003e: 3-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Thermostat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 12.43 pounds\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: RUUD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7URD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RUUD","offers":[{"title":"Default Title","offer_id":51283917209906,"sku":"7URD","price":176.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278068.png?v=1781063204","url":"https:\/\/voomisupply.com\/products\/ruud-7urd-zone-damper-7-inch-round-3-wire-24v","provider":"Voomi Supply","version":"1.0","type":"link"}
