It controls airflow within a ducted system by adjusting blade position across a modulating range, allowing precise zone-by-zone temperature management rather than simple open\/close switching. The unit measures 8 x 8 x 8 inches and weighs 5.2 pounds. Licensed HVAC technicians and commercial mechanical contractors are the primary installers. Its modulating action suits variable-air-volume and demand-controlled zoning strategies where staged airflow control is required.\u003c\/p\u003e\u003cp\u003eThe SC-ZD-08 is intended for commercial ducted HVAC systems where zoning control is needed across multiple occupied spaces. Its 8-inch round or rectangular duct interface fits standard commercial trunk-and-branch and plenum-bypass configurations. Typical installations include light commercial buildings, multi-zone rooftop unit systems, and retrofit zoning projects in office or retail environments. The modulating design supports integration with zone controllers or building automation systems that output a modulating control signal rather than a simple two-position command.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eModulating blade control for precise zone-by-zone airflow management\u003c\/li\u003e\n\u003cli\u003e8-inch duct size fits standard commercial trunk-and-branch layouts\u003c\/li\u003e\n\u003cli\u003eCompact 8 x 8 x 8 inch form factor simplifies installation in tight plenum spaces\u003c\/li\u003e\n\u003cli\u003eLightweight at 5.2 pounds for overhead and vertical duct mounting\u003c\/li\u003e\n\u003cli\u003eCompatible with zone controllers and building automation systems using modulating signal outputs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style modulating zone damper for commercial ducted HVAC systems requiring 8-inch damper assemblies with modulating actuator control.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with commercial zoning systems and applicable mechanical codes. De-energize the HVAC system and confirm the supply fan is off before inserting the damper into the duct. Secure the unit per the manufacturer instructions using sheet metal screws appropriate for the duct material, and verify the control wiring to the zone controller is complete and properly routed before restoring power. Refer to local mechanical codes and the zone control system wiring guide for signal type and terminal assignments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W x H x D)\u003c\/strong\u003e: 8 x 8 x 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper Type\u003c\/strong\u003e: Modulating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Commercial HVAC Zoning\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: SC-ZD-08\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":51437924057394,"sku":"SC-ZD-08","price":346.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313288319.png?v=1783449897","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-sc-zd-08-modulating-zone-damper-8in","provider":"Voomi Supply","version":"1.0","type":"link"}
