It controls airflow in zoned forced-air HVAC systems by opening or closing a duct run in response to a thermostat or zone controller signal. The damper ships actuator-free, allowing installers to pair it with the actuator of their choice. Licensed HVAC technicians install this component during new zoning system builds or when retrofitting single-zone systems to multi-zone configurations.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for residential and light commercial forced-air systems where zone control is required. It fits into 16 x 16 inch rectangular duct runs and is designed to accept a separately sourced two-position actuator. Typical installations include multi-zone split systems, heat pump systems, and gas furnace air handler setups where independent room or zone temperature control is the goal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e16 x 16 inch duct opening for standard rectangular duct runs\u003c\/li\u003e\n  \u003cli\u003eTwo-position operation  -  fully open or fully closed for reliable zone isolation\u003c\/li\u003e\n  \u003cli\u003eSupplied without actuator, allowing compatibility with installer-specified actuator models\u003c\/li\u003e\n  \u003cli\u003eShaft size range of 5\/8 to 1\/2 inch accommodates a range of actuator couplings\u003c\/li\u003e\n  \u003cli\u003ePackaged dimensions of 18 x 23 x 8 inches for straightforward staging and handling on the job\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 duct zoning systems requiring a 16 x 16 inch two-position damper without a pre-mounted actuator.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with zoned forced-air system design. Power down the air handler and zone controller before inserting the damper into the duct run and connecting actuator wiring. Verify the actuator shaft coupling matches the 5\/8 to 1\/2 inch shaft spec before mounting. Follow local mechanical codes and the zone controller manufacturer wiring requirements when completing the installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 16 x 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator\u003c\/strong\u003e: Not included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Size\u003c\/strong\u003e: 5\/8 to 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Two-position\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: 23 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: 9.04 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-NA-1616\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67952047423794,"sku":"HD-NA-1616","price":231.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e7ebe2e8a13c1ae983e6c74260ed8a4_7eb595d6-7a77-47c1-9112-55f822012f63.jpg?v=1791744842","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-hd-na-1616-zone-damper-16x16","provider":"Voomi Supply","version":"1.0","type":"link"}
