It controls airflow to a single zone by opening or closing on command from a zone control panel or thermostat. The unit measures 18 inches wide by 8 inches tall by 6 inches deep and weighs 6.5 pounds. Licensed HVAC technicians install this damper as part of a multi-zone residential or light commercial duct system where independent temperature control is required per zone.\u003c\/p\u003e\n\u003cp\u003eThis damper assembly is suited for rectangular duct applications in residential and light commercial forced-air systems. It operates in a two-position mode, meaning the blade moves fully open or fully closed rather than modulating to intermediate positions. Typical installations occur in main trunk lines or branch ducts where zone isolation is needed. The 18 x 8 inch duct size makes it a common fit for mid-capacity supply or return air runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-position operation for reliable open\/closed zone airflow control\u003c\/li\u003e\n  \u003cli\u003e18 x 8 inch duct size fits standard rectangular trunk and branch duct configurations\u003c\/li\u003e\n  \u003cli\u003eCompact 6-inch depth for installation in tight duct chases\u003c\/li\u003e\n  \u003cli\u003eZone One designation supports straightforward wiring to most zone control panels\u003c\/li\u003e\n  \u003cli\u003e6.5 pound assembly weight allows single-technician handling during 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 damper for rectangular forced-air duct systems requiring two-position zone control in residential and light commercial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with forced-air zoning systems and applicable mechanical codes. Shut down the air handler and de-energize the zone control panel before cutting into existing ductwork or making low-voltage wiring connections. Seal all duct joints after installation per local mechanical code requirements. Verify actuator operation and damper blade travel before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.5 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: D-Z1-1808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950028620082,"sku":"D-Z1-1808","price":412.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed39787339732d479be92f2ce474482b_7c21124c-64b6-4799-9625-55eb7495c52a.png?v=1791705646","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-d-z1-1808-zone-damper-assembly-18x8","provider":"Voomi Supply","version":"1.0","type":"link"}
