Zone dampers control airflow to individual zones in a ducted HVAC system, opening and closing on command from a zone controller or thermostat. The MD-1806 uses a 2-position actuator, meaning the damper blade moves fully open or fully closed rather than modulating to a partial position. The Belimo 3-wire actuator provides reliable, industry-standard operation with spring-return capability. Licensed HVAC technicians install this type of component during zone system commissioning or as a replacement in an existing zoned forced-air system.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for residential and light commercial zoning applications where rectangular duct runs require individual zone control. It mounts inline in a rectangular duct and connects to a low-voltage zone control panel. Typical installations include multi-zone forced-air heating and cooling systems where separate thermostats independently control airflow to each zone. The 18 inches x 6 inches duct opening size must match the existing ductwork dimensions at the installation point.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 inches x 6 inches rectangular form factor fits standard duct sizing\u003c\/li\u003e\n  \u003cli\u003e2-position operation: fully open or fully closed for straightforward zone control\u003c\/li\u003e\n  \u003cli\u003eBelimo 3-wire actuator provides proven, field-serviceable actuation\u003c\/li\u003e\n  \u003cli\u003eSpring-return design moves damper to a default position on power loss\u003c\/li\u003e\n  \u003cli\u003eLow-voltage control interface compatible with standard zone control panels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style zone damper for rectangular duct zoning systems requiring an 18 inches x 6 inches opening with a Belimo 3-wire 2-position actuator.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with low-voltage control wiring and zoned forced-air systems. Shut down the air handler and de-energize the zone control panel before installing or replacing the damper. The damper must be mounted with proper airflow direction as indicated on the unit, and low-voltage control wiring should be run in accordance with NEC guidelines and the zone controller manufacturer's wiring diagram. Do not operate the actuator manually with power applied.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Width\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Height\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Type\u003c\/strong\u003e: Rectangular 2-Position Zone Damper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator\u003c\/strong\u003e: Belimo 3-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 25 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: 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-1806\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950403092786,"sku":"MD-1806","price":243.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50bbd6f74b2edbde3fa9d504fe30cd5d_ec29e728-4272-4fe9-95e7-5ab6ad0ca252.jpg?v=1791716320","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-md-1806-rectangular-zone-damper-18x6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
