The damper operates in two positions  -  open or closed  -  allowing independent temperature control across separate zones in a building. At 18 inches wide by 14 inches tall, this damper fits standard rectangular duct openings of that size. The 2-wire actuator simplifies wiring and reduces installation time compared to multi-wire designs. Licensed HVAC technicians install this component as part of a complete zone control system.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for residential and light commercial ducted forced-air systems where zone control is required. It installs inline within rectangular ductwork to regulate conditioned air delivery to individual zones. The two-position design is appropriate for single-stage heating and cooling applications where full open and full closed operation meets the zoning demand. It is commonly used in multi-zone retrofits and new construction zoning layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-position (open\/closed) operation for straightforward zone control\u003c\/li\u003e\n  \u003cli\u003e2-wire actuator reduces field wiring complexity\u003c\/li\u003e\n  \u003cli\u003e18 inch by 14 inch rectangular duct opening size\u003c\/li\u003e\n  \u003cli\u003eFits standard rectangular ductwork inline installations\u003c\/li\u003e\n  \u003cli\u003eSuitable for residential and light commercial 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 rectangular ducted forced-air HVAC systems requiring two-position zone control.\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 zoning controls and ductwork. Power down the air handler and zone control panel before wiring the actuator. The damper must be installed in a section of rectangular ductwork that provides adequate clearance for actuator movement and service access. Follow local mechanical codes and manufacturer zone controller wiring instructions when integrating this damper into the zoning system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Width\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Height\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: 2-wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation\u003c\/strong\u003e: Two-position (open\/closed)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 18 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: 9 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: HD-1814\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67948946948402,"sku":"HD-1814","price":269.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5da16f12b9e92e16483a7f802f4c9e0_930db033-106a-4b57-a673-fd487393ddcc.jpg?v=1791677681","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-hd-1814-zone-damper-18x14-inch-2-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
