Operating on 24 volts, the damper uses a bottom-mounted motor with a 3-wire connection to provide reliable open and close control of airflow within a duct system. An integrated LED indicator light allows technicians to confirm motor position at a glance during installation and service. This unit is installed by licensed HVAC technicians as part of zoning or air quality control systems.\u003c\/p\u003e\n\u003cp\u003eThe END-8X20 is suited for residential and light commercial HVAC zoning systems where precise airflow management is required. Its rectangular profile fits standard 8-inch by 20-inch duct openings, making it a direct fit for common supply or return trunk configurations. The 24-volt control voltage is compatible with standard zone control panels and low-voltage thermostatic controls used in typical forced-air systems. Technicians working on air quality or multi-zone HVAC installations will find this damper a straightforward addition to existing ductwork.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24-volt operation compatible with standard zone control panels and low-voltage HVAC controls\u003c\/li\u003e\n  \u003cli\u003eRectangular form factor sized for 8-inch by 20-inch duct openings\u003c\/li\u003e\n  \u003cli\u003eBottom-mounted motor simplifies installation and access in tight duct configurations\u003c\/li\u003e\n  \u003cli\u003e3-wire motor connection supports standard open, close, and common wiring schemes\u003c\/li\u003e\n  \u003cli\u003eIntegrated LED indicator light provides visual confirmation of damper position\u003c\/li\u003e\n  \u003cli\u003eDesigned for air quality and zone control applications in forced-air systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style motorized damper replacement or new-installation component for rectangular duct systems requiring 24-volt zone or air quality control.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Always disconnect power to the air handler and zone control panel before installing or servicing the damper. The 3-wire low-voltage connection must be wired to a compatible zone control board following the control board manufacturer's wiring diagram. Verify duct dimensions and motor clearance before securing the damper in place.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: ND Motorized Damper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 8 inches x 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWires to Motor\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Mount\u003c\/strong\u003e: Bottom\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Quality\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeatures\u003c\/strong\u003e: LED Light\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: EWC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: END-8X20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51347576717618,"sku":"END-8X20","price":260.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554917.jpg?v=1782108928","url":"https:\/\/voomisupply.com\/products\/ewc-controls-end-8x20-nd-motorized-damper-8x20-in-24v","provider":"Voomi Supply","version":"1.0","type":"link"}
