It ships with a Belimo three-wire actuator that drives the blade between fully open and fully closed positions, enabling independent temperature control across separate zones within a ducted forced-air system. Licensed HVAC technicians install this damper directly into rectangular ductwork as part of a zoned air distribution setup. At 7 pounds, the unit is substantial enough for durable service while remaining manageable for a single-tech installation.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for rectangular supply or return duct runs in split-system or air handler applications where zone control is required. The two-position actuator responds to a 24-volt zone control panel signal, opening or closing the damper blade to direct conditioned air to the called zone. It is a common component in residential multi-zone retrofits and new construction zoning installations where individual room or area temperature control is the design goal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e14 x 8 inch rectangular duct opening matches standard residential duct sizes\u003c\/li\u003e\n  \u003cli\u003eBelimo three-wire actuator provides reliable two-position open and closed operation\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard 24-volt zone control panels and thermostats\u003c\/li\u003e\n  \u003cli\u003eFactory-mounted actuator reduces field assembly time\u003c\/li\u003e\n  \u003cli\u003e7-pound construction built for long-term in-duct service\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 ducted forced-air HVAC systems using 24-volt two-position zone controls.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with zoning systems and low-voltage control wiring. Shut down the air handler and de-energize the zone control panel before installing or wiring the damper. The damper must be oriented per the blade-rotation direction marked on the unit to ensure proper open and closed travel. Follow local mechanical codes and manufacturer wiring diagrams when connecting the three-wire actuator to the zone control board.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Width\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Height\u003c\/strong\u003e: 8 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\u003ePosition Type\u003c\/strong\u003e: 2 Position (Open \/ Closed)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10 inches wide x 21 inches tall x 8 inches deep\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7 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-1408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950373929266,"sku":"MD-1408","price":236.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50bbd6f74b2edbde3fa9d504fe30cd5d_75d93db0-937b-4c67-8574-753e48cc1781.jpg?v=1791715628","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-md-1408-rectangular-zone-damper-14x8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
