It ships without an actuator, allowing the installer to pair it with a compatible actuator of their choice. The damper accepts a 5\/8-inch to 1\/2-inch shaft and is designed to control airflow in zoned forced-air HVAC systems. At 13.04 pounds, it is a substantial assembly suited for commercial or larger residential applications. Licensed HVAC technicians are the primary installers for this type of component.\u003c\/p\u003e\n\u003cp\u003eThis damper is intended for use in zoned ducted HVAC systems where individual zones require independent airflow control. The no-actuator configuration makes it a practical choice when replacing a damper blade assembly while reusing an existing actuator, or when sourcing the actuator separately to match a specific control board or zone controller. It fits a 20-inch by 20-inch duct opening and is applicable in both residential and light commercial forced-air systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-position operation for open\/closed zone airflow control\u003c\/li\u003e\n  \u003cli\u003eSized for 20-inch by 20-inch duct applications\u003c\/li\u003e\n  \u003cli\u003eShips without actuator, allowing actuator selection to match existing control system\u003c\/li\u003e\n  \u003cli\u003eCompatible with 5\/8-inch to 1\/2-inch shaft actuators\u003c\/li\u003e\n  \u003cli\u003eRobust construction at 13.04 pounds for durable long-term installation\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 20-inch by 20-inch ducted forced-air HVAC zoning systems requiring a two-position damper without an actuator.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Shut down the air handler and disconnect power to the zoning control system before installing or servicing this damper. Verify the replacement actuator shaft size matches the 5\/8-inch to 1\/2-inch shaft specification before mounting. Follow local mechanical codes and manufacturer guidelines for duct penetration, fastening, and actuator wiring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Size\u003c\/strong\u003e: 20 x 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Size\u003c\/strong\u003e: 5\/8 to 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 26 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: 13.04 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-2020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67948821774642,"sku":"HD-NA-2020","price":268.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e7ebe2e8a13c1ae983e6c74260ed8a4_30c2a31f-08db-4bfc-881c-acecc516b261.jpg?v=1791673758","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-hd-na-2020-zone-damper-20x20","provider":"Voomi Supply","version":"1.0","type":"link"}
