Installed within ductwork, it opens and closes to direct conditioned air to specific zones based on thermostat demand. This damper integrates into multi-zone control systems, allowing independent temperature management across different areas of a structure. Weighing 10 pounds and measuring 12 inches wide by 38 inches high by 9 inches deep in its packaged form, the SD-2810 is sized for commercial and residential applications requiring larger duct openings. Licensed HVAC technicians typically handle installation and system commissioning.\u003c\/p\u003e\u003cp\u003eThe SD-2810 is suited for use in residential and light commercial forced-air zoning systems where a 28 x 10 duct opening is present. It functions as an auxiliary damper, meaning it operates in coordination with a primary zone control panel and actuator assembly. Typical installation scenarios include trunk-and-branch duct systems and larger residential builds where multiple zones require independent airflow control. This damper is appropriate for applications demanding a reliable, larger-format zone control component within an existing or new zoning layout.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e28 x 10 duct opening size suits larger residential and light commercial duct runs\u003c\/li\u003e\n\u003cli\u003eAuxiliary zone damper design integrates with zone control panels and actuators\u003c\/li\u003e\n\u003cli\u003ePackaged dimensions of 12 inches wide by 38 inches high by 9 inches deep for straightforward staging and handling\u003c\/li\u003e\n\u003cli\u003e10-pound unit weight supports practical field handling during installation\u003c\/li\u003e\n\u003cli\u003eCompatible with standard multi-zone forced-air control architectures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style auxiliary zone damper for use in forced-air zoning systems requiring a 28 x 10 duct opening size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with forced-air zoning systems and local mechanical codes. Power down the air handler and zone control panel before beginning any duct or damper work. Ensure the duct opening is correctly sized and the actuator is properly mounted and wired per the zone controller manufacturer specifications before restoring power. Consult applicable local mechanical codes and the zone control system documentation for wiring and commissioning requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Opening Size\u003c\/strong\u003e: 28 x 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaged Width\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaged Height\u003c\/strong\u003e: 38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaged Depth\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SD-2810\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67948917031218,"sku":"SD-2810","price":439.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6c59a381d0e8005908f8e0a8d621c71_3ca105f6-b05f-4f4f-b685-7a508eeb68e8.png?v=1791676526","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-sd-2810-auxiliary-zone-damper-28x10","provider":"Voomi Supply","version":"1.0","type":"link"}
