The damper uses a power open\/power closed, 3-wire motor rated at 17 inch-pounds of torque, giving it the authority to hold blade position accurately under system static pressure. A manual gear release is included for service situations. The motor is UL listed and NEMA Class 2 certified. Nylon bushings reduce operational noise, and an onboard LED display lets the installer verify open and closed positions without a separate meter.\u003c\/p\u003e\n\u003cp\u003eThis damper is designed for installation in rectangular supply or return duct runs as part of a multi-zone forced-air system. It fits a 16-inch by 8-inch duct opening. The ND Series is built to work within the EWC Ultra-Zone zoning system, pairing with compatible zone controllers to deliver independent temperature control across multiple areas of a structure. The quick-connecting terminal block accepts direct wire terminations without wire nuts, which speeds commissioning and simplifies future service calls. The damper carries a 97 percent leak-proof rating, with overlapping blades that limit bypass air between zones.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePower open \/ power closed 3-wire operation with 17 inch-pounds of motor torque\u003c\/li\u003e\n  \u003cli\u003eUL listed motor with NEMA Class 2 certification\u003c\/li\u003e\n  \u003cli\u003eOnboard LED display for visual confirmation of damper position during checkout\u003c\/li\u003e\n  \u003cli\u003eManual gear release for service access without power\u003c\/li\u003e\n  \u003cli\u003eNylon bushing construction for reduced operational noise\u003c\/li\u003e\n  \u003cli\u003e97 percent leak-proof rating with overlapping blade design\u003c\/li\u003e\n  \u003cli\u003eTool-free quick-connect terminal block eliminates wire nuts\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 16-inch by 8-inch rectangular duct openings in residential and light commercial forced-air HVAC installations.\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. Shut down the air handler and de-energize the zone control panel before wiring or mounting the damper. Verify duct dimensions and airflow direction before fastening the damper frame into the duct. Consult local mechanical codes and the zone controller wiring diagram when making low-voltage control connections at the terminal block.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 16 x 8 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 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\u003eOverall Length\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall 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-16X8-MA15S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51345327554866,"sku":"END-16X8-MA15S","price":272.18,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555105.webp?v=1782054848","url":"https:\/\/voomisupply.com\/products\/ewc-controls-end-16x8-ma15s-nd-series-motorized-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
