Part of the ND Ultra-Zone series, it uses a power open\/power closed, 3-wire control configuration to regulate airflow across individual zones with a 97 percent leak-proof rating achieved through overlapping blades and a positive off motor. The motor delivers 17 inch-pounds of torque and includes a manual gear release for service access. Nylon bushings reduce operating noise, and onboard LEDs provide instant visual confirmation of damper position for fast diagnostics during commissioning or troubleshooting. Licensed HVAC technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis damper is intended for ducted forced-air HVAC systems using zone control. The 16 x 10 inch frame size fits standard rectangular duct openings of that dimension. The ND series is designed to work in conjunction with the EWC Ultra-Zone zoning system. The motor is always factory-mounted on the second dimension specified, which on this unit is the 10-inch dimension. A quick-connecting terminal block eliminates wire nuts and simplifies field wiring. The heavy-duty frame seats securely in the duct for faster installation compared to lighter-gauge damper bodies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePower open\/power closed 3-wire operation for positive zone control\u003c\/li\u003e\n  \u003cli\u003e97 percent leak-proof rating via overlapping blades and positive off motor\u003c\/li\u003e\n  \u003cli\u003e17 inch-pounds of motor torque with manual gear release\u003c\/li\u003e\n  \u003cli\u003eLED indicators for real-time damper position diagnostics\u003c\/li\u003e\n  \u003cli\u003eNylon bushings for quieter operation and extended motor life\u003c\/li\u003e\n  \u003cli\u003eQuick-connecting terminal block eliminates wire nuts for faster field wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the EWC Ultra-Zone zoning system and compatible with standard rectangular duct openings measuring 16 x 10 inches.

Disconnect and lock out power to the air handler and zone control panel before beginning installation. Confirm duct opening dimensions before mounting, and verify that the terminal block wiring matches the zone controller output configuration. Do not force the manual gear release while the motor is energized.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Size\u003c\/strong\u003e: 16 x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Power Open \/ Power Closed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiring\u003c\/strong\u003e: 3-wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Torque\u003c\/strong\u003e: 17 inch-pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeak Rating\u003c\/strong\u003e: 97 percent 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\u003eBushing Material\u003c\/strong\u003e: Nylon\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.4 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-16X10-MA15S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51346289131826,"sku":"END-16X10-MA15S","price":286.23,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555028.webp?v=1782076426","url":"https:\/\/voomisupply.com\/products\/ewc-controls-end-16x10-ma15s-motorized-zone-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
