It controls airflow through individual zones by opening and closing on command from a zone control board or thermostat signal. The SD-07 installs inside round ductwork and integrates with multi-zone systems to direct conditioned air where it is needed. HVAC technicians and sheet metal installers are the primary trade for this component. At 4 pounds, the unit is compact enough for tight mechanical room or attic installations.\u003c\/p\u003e\u003cp\u003eThis damper is suited for residential forced-air zoning applications where individual room or area control is required. It functions as an auxiliary damper, meaning it supplements a primary zoning setup to provide additional zone coverage. Typical install scenarios include new construction zoning retrofits and system expansions where additional zone control points are added to an existing ducted system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-inch round design fits standard round duct runs used in residential zoning layouts\u003c\/li\u003e\n\u003cli\u003eAuxiliary damper function supports multi-zone system expansion without replacing existing zone hardware\u003c\/li\u003e\n\u003cli\u003eCompact footprint with overall dimensions of 11 inches wide by 13 inches tall by 11 inches deep\u003c\/li\u003e\n\u003cli\u003eLightweight at 4 pounds for straightforward overhead or attic duct installation\u003c\/li\u003e\n\u003cli\u003eCompatible with low-voltage zone control systems commonly used in residential HVAC applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style auxiliary zone damper for use with low-voltage residential and light commercial HVAC zoning systems accepting a 7-inch round damper configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with zoning system wiring and ductwork. Power down the air handler and zone control board before making any electrical connections to the damper actuator. Verify that the duct opening is clean and properly sized to 7 inches before mounting. Follow the zone control manufacturer wiring instructions and applicable local mechanical codes during installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 7 inches round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 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-07\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950445822258,"sku":"SD-07","price":245.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68323c27c54e9f0dc3067f687c08fcda_7a7aef38-f4e7-43df-8ecc-fe2e64b6cabd.png?v=1791718020","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-sd-07-round-zone-damper-7-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
