It is designed for use in forced-air zoning systems where individual zones require independent airflow control. The damper opens and closes in response to a 24-volt zone control signal, allowing a single air handler or furnace to condition multiple zones without manual intervention. At 18 pounds, it is a substantial assembly built for commercial-grade duct installations. Licensed HVAC technicians and sheet metal contractors are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for rectangular duct applications in both light commercial and residential zoning systems. A 24 x 24 inch face size accommodates high-volume supply or return trunk duct runs where significant airflow capacity is required. The integrated Belimo 3-wire actuator provides spring-return, fail-safe operation, ensuring the damper defaults to a defined position on power loss. This makes it appropriate for systems where airflow safety or equipment protection is a design requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24 x 24 inch rectangular face size for high-capacity duct runs\u003c\/li\u003e\n  \u003cli\u003e2-position operation: fully open or fully closed for precise zone control\u003c\/li\u003e\n  \u003cli\u003eIntegrated Belimo 3-wire actuator with spring-return fail-safe function\u003c\/li\u003e\n  \u003cli\u003e24-volt control signal compatible with standard zone control boards\u003c\/li\u003e\n  \u003cli\u003eRobust construction at 18 pounds rated for sustained commercial-duty cycling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation damper for rectangular duct zoning systems requiring a 24 x 24 inch 2-position zone damper with a Belimo 3-wire actuator.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handler and de-energize the control panel before mounting or wiring the damper. The damper must be mounted in the ductwork in strict accordance with the manufacturer orientation markings to ensure proper spring-return travel direction. Wire the actuator per the Belimo 3-wire wiring diagram and verify zone board compatibility before commissioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Height\u003c\/strong\u003e: 24 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\u003eOperation\u003c\/strong\u003e: 2-Position (Open\/Closed)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 26 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 30 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: 18 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: MD-2424\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67951969435954,"sku":"MD-2424","price":420.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50bbd6f74b2edbde3fa9d504fe30cd5d_518dda52-cdc1-47cc-a113-57e86cf636a4.jpg?v=1791742733","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-md-2424-rectangular-zone-damper-24x24-in","provider":"Voomi Supply","version":"1.0","type":"link"}
