It is designed to control airflow in ducted HVAC zoning systems by opening and closing on command from a zone control board or thermostat. The bottom-mount actuator configuration suits tight duct runs where side access is limited. Licensed HVAC technicians install this damper as part of residential or light-commercial zoning layouts. At 8 pounds, it is a manageable single-tech installation in most attic, basement, or mechanical-room duct configurations.\u003c\/p\u003e\u003cp\u003eThis damper is suited for rectangular duct zoning applications in forced-air systems, both residential and light-commercial. The Belimo three-wire actuator allows spring-return or end-switch-driven operation depending on control board wiring. It fits standard rectangular duct openings where the 24-inch by 6-inch nominal size matches the existing ductwork. Typical install scenarios include multi-zone split systems, heat pumps, and gas furnace air handlers where independent room or floor control is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e24 inches x 6 inches nominal rectangular form factor fits standard duct openings\u003c\/li\u003e\n\u003cli\u003eBelimo three-wire actuator provides reliable two-position open\/close operation\u003c\/li\u003e\n\u003cli\u003eBottom-mount actuator configuration accommodates restricted side-clearance installations\u003c\/li\u003e\n\u003cli\u003eTwo-position operation integrates with standard zone control boards and low-voltage thermostats\u003c\/li\u003e\n\u003cli\u003e8-pound unit weight supports single-technician handling during installation\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 ducted forced-air HVAC zoning systems using Belimo three-wire actuator wiring schemes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with applicable mechanical codes. Power down the air handler and de-energize all zone control boards before wiring or mounting the damper. Secure the damper firmly to the duct collar to prevent air bypass around the frame. Verify actuator wiring polarity and end-switch configuration against the zone control board specifications before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper Size\u003c\/strong\u003e: 24 inches x 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper Type\u003c\/strong\u003e: Rectangular Two-Position Zone Damper\u003c\/li\u003e\n\u003cstrong\u003eActuator Brand\u003c\/strong\u003e: Belimo\u003cli\u003e\n\u003cstrong\u003eActuator Wiring\u003c\/strong\u003e: 3 Wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Mount\u003c\/strong\u003e: Bottom Mount\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: 28 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: 8 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-2406-BM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950481899826,"sku":"MD-2406-BM","price":266.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75f2b6c2829c7454f6fbae3d993a1e9d_a6bd9c3c-f874-40f6-a74b-fd46d92bbf9b.png?v=1791719212","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-md-2406-bm-rectangular-zone-damper-24x6","provider":"Voomi Supply","version":"1.0","type":"link"}
