Measuring 28 inches by 12 inches, it ships with a Belimo actuator that operates on a 3-wire control circuit and cycles open or closed in approximately 35 seconds. Zone dampers like this one regulate conditioned airflow to individual zones, allowing a zoning controller to direct heating or cooling only where it is needed. Licensed HVAC technicians install this component as part of a multi-zone duct system, typically alongside a compatible zoning control panel and thermostat network.\u003c\/p\u003e\n\u003cp\u003eThis damper is intended for rectangular duct applications in residential and light-commercial forced-air systems. The 28-by-12-inch blade size fits a common duct dimension found in trunk-and-branch and plenum-style distribution layouts. The integrated Belimo actuator eliminates the need for a separate motor assembly, simplifying rough-in. It is well suited for new-construction zoning installations as well as retrofit zoning upgrades where the existing ductwork matches the damper opening size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e28-inch by 12-inch rectangular blade fits standard duct openings of that dimension\u003c\/li\u003e\n  \u003cli\u003eIntegrated Belimo actuator included  -  no separate motor purchase required\u003c\/li\u003e\n  \u003cli\u003e3-wire control circuit compatible with standard zoning control panels\u003c\/li\u003e\n  \u003cli\u003e35-second actuator travel time provides controlled, gradual airflow modulation\u003c\/li\u003e\n  \u003cli\u003eShips as a complete damper-and-actuator assembly ready for installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style zone damper replacement or new-installation component for rectangular forced-air duct systems requiring a 28-inch by 12-inch opening with a 3-wire Belimo-style actuator.

Power down the air handler and disconnect the zoning control panel before making any wiring connections. The 3-wire actuator requires a dedicated control circuit from the zoning panel  -  consult the panel manufacturer wiring diagram before terminating leads. Follow all applicable local mechanical codes and manufacturer instructions for duct penetration, fastening, and low-voltage wiring clearances.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Width\u003c\/strong\u003e: 28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Height\u003c\/strong\u003e: 12 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 Travel Time\u003c\/strong\u003e: 35 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 35 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Depth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.73 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: RM-2812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67948926566706,"sku":"RM-2812","price":347.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/745ecffd07cbe47f75f5847deb081dca_6a468d93-a631-49b9-bd2c-0b4667ee11b8.jpg?v=1791676919","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-rm-2812-rectangular-zone-damper-28x12","provider":"Voomi Supply","version":"1.0","type":"link"}
