It ships with a Belimo three-wire actuator mounted on the bottom of the damper frame. The two-position actuator drives the damper blade fully open or fully closed in response to a 24-volt zone control signal, making it a straightforward fit for residential and light commercial zoning applications. HVAC technicians install this damper directly into rectangular sheet metal ductwork to divide a system into independently controlled zones. The unit weighs 10 pounds and the overall assembly dimensions are 17 inches wide by 27 inches tall by 8 inches deep.\u003c\/p\u003e\u003cp\u003eThis damper is suited for residential and light commercial forced-air zoning installations where a dedicated control board or zone controller issues open and close commands over low-voltage wiring. The bottom-mount actuator position is appropriate for horizontal or vertical duct runs where access to the bottom of the duct is available. Installers typically use it on trunk lines or branch ducts feeding individual zones in a multi-zone split system or air handler setup. No field-supplied actuator is needed; the Belimo three-wire actuator is included and factory-mounted.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e24 inches by 12 inches rectangular duct opening for direct duct integration\u003c\/li\u003e\n\u003cli\u003eFactory-mounted Belimo three-wire actuator for two-position open and close operation\u003c\/li\u003e\n\u003cli\u003eBottom-mount actuator position accommodates a wide range of duct orientations\u003c\/li\u003e\n\u003cli\u003eLow-voltage 24-volt control signal compatible with standard zone control boards\u003c\/li\u003e\n\u003cli\u003eComplete assembly ships ready to install with no separate actuator sourcing required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for rectangular forced-air duct systems controlled by standard 24-volt two-position zone controllers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with forced-air zoning systems and low-voltage control wiring. De-energize the air handler or furnace and the zone control panel before wiring or mounting the damper. The damper should be installed in a straight duct section with sufficient clearance around the actuator for service access. Wire the actuator to the zone control board per the controller manufacturer's low-voltage wiring diagram and verify proper open and close operation before restoring system power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Opening Width\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Opening Height\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper Configuration\u003c\/strong\u003e: 2 Position (Open and Closed)\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 Mount Position\u003c\/strong\u003e: Bottom Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembly Width\u003c\/strong\u003e: 17 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembly Height\u003c\/strong\u003e: 27 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembly Depth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-2412-BM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67949666304306,"sku":"MD-2412-BM","price":289.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75f2b6c2829c7454f6fbae3d993a1e9d_e0c0acbb-9235-445f-88a0-62693f6bc137.png?v=1791697400","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-md-2412-bm-rectangular-zone-damper-24x12","provider":"Voomi Supply","version":"1.0","type":"link"}
