Part of the ND Ultra-Zone series, it features a side-mounted motor and a 3-wire connection to control airflow in ductwork as part of a multi-zone climate system. An onboard LED indicator lets technicians visually confirm damper position during commissioning without additional test equipment. The reinforced frame speeds up duct installation, and nylon bushings reduce operating noise for quieter long-term performance. Licensed HVAC technicians are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThe END-12X8 fits rectangular duct openings measuring 12 inches by 8 inches and is rated for air quality and zoning control applications. It is suited for new-construction zoning layouts and retrofit zone-control upgrades in forced-air systems. The 3-wire motor interface is compatible with standard zone control panels and thermostats that output a 24-volt signal. The LED display simplifies field checkout, reducing commissioning time and the likelihood of callback service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLED indicator light for visual damper position verification during installation and checkout\u003c\/li\u003e\n\u003cli\u003e24-volt, 3-wire motor connection compatible with standard zoning control panels\u003c\/li\u003e\n\u003cli\u003eSide-mounted motor design for accessible installation in tight duct chases\u003c\/li\u003e\n\u003cli\u003eNylon bushings reduce mechanical noise during damper operation\u003c\/li\u003e\n\u003cli\u003eReinforced rectangular frame for faster, more secure duct fitment\u003c\/li\u003e\n\u003cli\u003eDesigned for air quality and zoning control in forced-air HVAC systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation damper for rectangular duct zoning systems requiring a 12-inch by 8-inch motorized damper with 24-volt control.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with low-voltage zoning controls and ductwork modification. Disconnect power to the air handler and zone control panel before wiring the damper motor. Verify the duct opening matches the 12-inch by 8-inch damper frame dimensions before securing to avoid air bypass. Follow the zone control manufacturer wiring diagram for proper 3-wire connection to prevent motor damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Motorized Zone Damper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 12 inches x 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangular\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: Side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures\u003c\/strong\u003e: LED Indicator Light\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Quality and 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: EWC CONTROLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: END-12X8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51346707317042,"sku":"END-12X8","price":241.85,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554870.jpg?v=1782088004","url":"https:\/\/voomisupply.com\/products\/ewc-controls-end-12x8-motorized-zone-damper-12x8-24v","provider":"Voomi Supply","version":"1.0","type":"link"}
