The unit measures 18 inches by 6 inches and uses a three-wire actuator to drive the blade between fully open and fully closed positions. An onboard LED indicator provides a quick visual reference of damper state without requiring a meter or test light. Licensed HVAC technicians install this damper inline within rectangular ductwork as part of a zoned forced-air system controlled by a compatible zone control board.\u003c\/p\u003e\n\u003cp\u003eThe ld-1806 is suited for residential zoning applications where individual rooms or zones require independent temperature control. It fits within standard 18-inch by 6-inch rectangular duct runs and integrates with three-wire zone control wiring schemes common in residential multi-zone forced-air heating and cooling systems. This damper is appropriate for new construction zone installations and retrofit zoning projects alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRectangular damper sized at 18 inches by 6 inches for direct duct fitment\u003c\/li\u003e\n  \u003cli\u003eTwo-position actuator drives blade fully open or fully closed on demand\u003c\/li\u003e\n  \u003cli\u003eThree-wire actuator wiring compatible with standard residential zone control boards\u003c\/li\u003e\n  \u003cli\u003eOnboard LED indicator shows damper position at a glance\u003c\/li\u003e\n  \u003cli\u003eDesigned for residential forced-air zoning applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for residential rectangular duct zoning systems requiring an 18-inch by 6-inch two-position damper with a three-wire actuator.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with residential zoning systems. Power down the air handler and zone control board before wiring or inserting the damper into the duct. Secure the damper to the duct using sheet metal screws and seal edges with approved HVAC foil tape to prevent bypass air leakage. Verify actuator wiring against the zone control board manufacturer wiring diagram before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 18 inches x 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Three-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePosition Type\u003c\/strong\u003e: Two-Position (Open\/Closed)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential\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: ld-1806\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":51268766466354,"sku":"LD-1806","price":227.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308910717.jpg?v=1780705307","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-ld-1806-rectangular-zone-damper-18x6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
