It controls airflow within a duct system by adjusting blade position across a range of positions rather than switching between fully open and fully closed states only. This modulating action allows precise zone-by-zone temperature management in multi-zone commercial systems. The damper measures 18 inches wide by 16 inches tall with a depth of 6 inches and weighs 10.5 pounds. Licensed HVAC technicians and commercial mechanical contractors are the typical installers for this unit.\u003c\/p\u003e\n\u003cp\u003eThe ZD-1816 is intended for commercial zoning systems where variable airflow control is required across multiple zones. Its 18-inch by 16-inch face size suits medium to large commercial duct configurations. Modulating dampers in this class are commonly found in variable air volume (VAV) arrangements, multi-zone rooftop unit systems, and commercial air handling unit installations where zone-level airflow must be independently regulated to meet load demands.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eModulating operation for precise, variable airflow control rather than simple open\/closed switching\u003c\/li\u003e\n  \u003cli\u003e18 inches wide by 16 inches tall face dimensions suit medium to large commercial duct openings\u003c\/li\u003e\n  \u003cli\u003e6-inch depth accommodates standard commercial duct installations\u003c\/li\u003e\n  \u003cli\u003e10.5-pound construction reflects robust commercial-grade build quality\u003c\/li\u003e\n  \u003cli\u003eDesigned for multi-zone commercial HVAC system integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style modulating zone damper for commercial multi-zone HVAC duct systems requiring an 18-inch by 16-inch damper section.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified mechanical contractor in accordance with applicable mechanical codes. Disconnect and lock out power to the air handling equipment and any associated zone control panel before beginning installation. Verify duct dimensions and damper orientation before securing the unit in place. Actuator wiring must comply with the zone controller manufacturer specifications and applicable sections of the NEC.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.5 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: ZD-1816\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67951483126066,"sku":"ZD-1816","price":547.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4310108ccf7e1990ea808f6067adcc58_718aa785-d7c6-424e-b009-1195192bc577.png?v=1791727481","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-zd-1816-modulating-zone-damper-18x16","provider":"Voomi Supply","version":"1.0","type":"link"}
