Operating at 24 volts, it features a bottom-mounted motor that drives the blade to the open or closed position with a 15-second actuation time. The damper measures 8 inches by 24 inches and uses a 3-wire motor connection for straightforward integration with standard zone control boards. Licensed HVAC technicians install this component during zoned system commissioning, service, or retrofit work.\u003c\/p\u003e\n\u003cp\u003eThe END-8X24-MA15S is suited for residential and light commercial zoning applications where precise airflow regulation is required. Its rectangular profile fits standard 8-inch by 24-inch duct openings, making it a practical choice for multi-zone forced-air systems. The built-in LED indicator assists with visual status confirmation during installation and troubleshooting. Air quality control setups that require motorized zone dampers with reliable, repeatable actuation are a typical application for this unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24-volt operation compatible with standard zone control low-voltage wiring\u003c\/li\u003e\n  \u003cli\u003e15-second motor actuation time for smooth, controlled blade movement\u003c\/li\u003e\n  \u003cli\u003e3-wire motor connection for integration with zone control boards\u003c\/li\u003e\n  \u003cli\u003eBottom-mounted motor for accessible installation in tight duct runs\u003c\/li\u003e\n  \u003cli\u003eBuilt-in LED indicator for visual status confirmation\u003c\/li\u003e\n  \u003cli\u003eRectangular 8-inch by 24-inch profile fits standard rectangular duct openings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style motorized zone damper for rectangular ducted HVAC zoning systems requiring 24-volt, 3-wire actuator control in air quality applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Disconnect power to the air handler and zone control board before wiring or mounting the damper. Verify duct opening dimensions match the damper frame before securing to avoid air bypass around the blade. Follow NEC low-voltage wiring guidelines when connecting the 3-wire motor leads to the zone control board.\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\u003eSize\u003c\/strong\u003e: 8 inches x 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Actuation Time\u003c\/strong\u003e: 15 seconds\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\u003eFeatures\u003c\/strong\u003e: LED Light\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Quality\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-8X24-MA15S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51344201548082,"sku":"END-8X24-MA15S","price":299.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555032.jpg?v=1782031595","url":"https:\/\/voomisupply.com\/products\/ewc-controls-end-8x24-ma15s-nd-motorized-damper-8x24-in","provider":"Voomi Supply","version":"1.0","type":"link"}
