It ships with a Belimo 3-wire actuator that opens and closes the damper blade in approximately 35 seconds, providing reliable airflow control across individual zones. The compact assembly fits into existing round ductwork without major duct modification, making it a practical choice for retrofit zoning projects. Licensed HVAC technicians install this damper as part of a multi-zone control system paired with a zone control board and low-voltage thermostat wiring.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for retrofit zoning applications in residential forced-air systems where round duct runs are already in place. The 3-wire actuator configuration supports both normally open and normally closed control sequences depending on zone panel requirements. It fits 10-inch round duct and is sized for typical trunk-to-branch or branch duct installations where individual room or area control is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-inch round damper body sized for standard round ductwork retrofit installations\u003c\/li\u003e\n  \u003cli\u003eBelimo 3-wire actuator included for precise open and close positioning\u003c\/li\u003e\n  \u003cli\u003e35-second actuator stroke time for smooth, controlled airflow modulation\u003c\/li\u003e\n  \u003cli\u003eRetro-fit design allows installation into existing duct systems without major modification\u003c\/li\u003e\n  \u003cli\u003eLow-voltage actuator compatible with standard HVAC zone control boards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and retrofit zone damper for residential and light commercial forced-air HVAC zoning systems using 10-inch round ductwork.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with zoning system wiring and duct fabrication. Shut down the air handler and de-energize the zone control board before installing or wiring the actuator. Secure the damper body to the duct using sheet metal screws and seal with duct tape or mastic per applicable mechanical codes. Connect low-voltage actuator leads to the zone control board according to the zone panel manufacturer's wiring diagram.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Belimo 3-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Stroke Time\u003c\/strong\u003e: 35 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Depth\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.5 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: IO HVAC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RRD-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67949683671346,"sku":"RRD-10","price":158.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe4d0583c4e9e56b8a9f172f22451cf1_56d3ea7f-5845-4f30-8c1d-9860677a24a6.png?v=1791697923","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-rrd-10-round-retro-zone-damper-10-in","provider":"Voomi Supply","version":"1.0","type":"link"}
