Sized at 8 inches by 16 inches, it fits standard rectangular ductwork and delivers reliable airflow control across individual zones. The damper runs on a power-open\/power-closed, 3-wire motor rated at 17 inch-pounds of torque with a manual gear release for service access. Nylon bushings reduce blade noise during operation, and overlapping blades with a strong positive-off motor provide a 97% leak-proof rating. Built-in fail-safe LEDs give technicians quick visual confirmation of damper position during commissioning and diagnostics. Licensed HVAC technicians are the typical installing trade for this component.\u003c\/p\u003e\n\u003cp\u003eThe END-8X16-MA15S is suited for residential and light-commercial forced-air zoning applications. It is part of the EWC CONTROLS Ultra-Zone ND series, designed to pair with Ultra-Zone zoning control systems. The damper mounts directly in rectangular supply or return ductwork and uses a quick-connect terminal block that eliminates wire nuts, reducing field wiring time. Its reinforced frame supports faster installation in tight duct chases and keeps the blade assembly square for consistent seal performance across the service life of the unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePower-open\/power-closed 3-wire motor operation with manual gear release\u003c\/li\u003e\n  \u003cli\u003e17 inch-pounds of motor torque for positive blade actuation and accurate zone control\u003c\/li\u003e\n  \u003cli\u003e97% leak-proof rating via overlapping blades and positive-off motor\u003c\/li\u003e\n  \u003cli\u003eNylon bushings for quiet operation and extended motor service life\u003c\/li\u003e\n  \u003cli\u003eOnboard LED display and fail-safe LEDs for fast field diagnostics\u003c\/li\u003e\n  \u003cli\u003eQuick-connect terminal block eliminates wire nuts and speeds up wiring\u003c\/li\u003e\n  \u003cli\u003eUL-listed motor with NEMA Class 2 certification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the EWC CONTROLS Ultra-Zone zoning system and compatible with standard 8-inch by 16-inch rectangular HVAC ductwork installations requiring motorized zone damper control.\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. Disconnect and lock out power to the air handler and zone control board before mounting the damper or making wiring connections. The quick-connect terminal block must be fully seated before restoring power. Verify damper blade position and LED status indicators during system commissioning to confirm proper open and closed operation in each zone.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Size\u003c\/strong\u003e: 8 inches x 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Torque\u003c\/strong\u003e: 17 inch-pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Operation\u003c\/strong\u003e: Power open \/ power closed, 3-wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeak Rating\u003c\/strong\u003e: 97% leak-proof\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Certification\u003c\/strong\u003e: UL Listed, NEMA Class 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 14 inches\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.8 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: EWC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: END-8X16-MA15S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51346055823666,"sku":"END-8X16-MA15S","price":279.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555081.webp?v=1782069956","url":"https:\/\/voomisupply.com\/products\/ewc-controls-end-8x16-ma15s-motorized-zone-damper-8x16","provider":"Voomi Supply","version":"1.0","type":"link"}
