Zone dampers are used in forced-air zoning systems to direct conditioned air to specific areas of a building by opening or closing airflow paths on demand from a zone controller. This damper ships ready for field-mount actuator installation, giving the installer flexibility to pair it with the actuator of choice for the application. At 15.04 pounds, it is a substantial steel-construction unit suited for commercial or larger residential ducted systems. Licensed HVAC technicians and sheet-metal contractors are the typical installers for this type of component.\u003c\/p\u003e\n\u003cp\u003eThe HD-NA-2620 is intended for use in ducted forced-air HVAC zoning systems where two-position airflow control is required. Its 26-by-20-inch face size makes it appropriate for larger trunk or branch duct runs in commercial light-commercial or larger residential installations. Because no actuator is included, the installer selects and mounts the actuator on-site, which is common practice when integrating into an existing zone control panel or when a specific actuator torque rating or brand is required by the system design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e26-inch by 20-inch face size for larger duct applications\u003c\/li\u003e\n  \u003cli\u003eTwo-position operation for open\/close zone control\u003c\/li\u003e\n  \u003cli\u003eActuator-free design allows field selection of compatible actuator\u003c\/li\u003e\n  \u003cli\u003e5\/8-to-1\/2-inch shaft accommodates standard actuator drive sizes\u003c\/li\u003e\n  \u003cli\u003eWeighs 15.04 pounds  -  robust construction for long service life\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 forced-air ducted HVAC zoning systems requiring a two-position damper at a 26-by-20-inch duct opening.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet-metal contractor. Power the zone control panel down completely before wiring any actuator to the damper shaft. Verify that the selected actuator shaft size matches the 5\/8-to-1\/2-inch shaft before mounting. Follow local mechanical codes and manufacturer actuator instructions for secure shaft coupling and damper blade alignment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Size\u003c\/strong\u003e: 26 inches 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\u003eOperation Type\u003c\/strong\u003e: Two-position\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 15.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 33 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Depth\u003c\/strong\u003e: 8 inches\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-2620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67952876585266,"sku":"HD-NA-2620","price":368.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e7ebe2e8a13c1ae983e6c74260ed8a4_f0a1703b-f616-4a97-83c3-359fec97028a.jpg?v=1791753744","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-hd-na-2620-zone-damper-26x20-no-actuator","provider":"Voomi Supply","version":"1.0","type":"link"}
