Part of the ND series Ultra-Zone damper line, it uses a power open\/power closed, 3-wire motor configuration to deliver precise airflow control across individual zones. The motor produces 17 inch-pounds of torque and includes a manual gear release for service convenience. An onboard LED display allows technicians to verify damper position during commissioning without additional test equipment. Nylon bushings reduce operating noise, and the overlapping blade design delivers a 97% leak-proof rating for accurate zone isolation.\u003c\/p\u003e\n\u003cp\u003eThis damper is sized at 14 x 10 inches and is intended for residential and light commercial duct systems where multi-zone temperature control is required. It is designed to integrate with the EWC Controls Ultra-Zone zoning system but is also suitable for comparable low-voltage zoning control applications. The quick-connecting terminal block eliminates wire nuts and speeds up field wiring. Licensed HVAC technicians typically install this damper during new zoning system installations or when retrofitting existing ductwork for zone control.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePower open\/power closed 3-wire motor operation for active zone control in both directions\u003c\/li\u003e\n  \u003cli\u003e17 inch-pounds of motor torque with manual gear release for service access\u003c\/li\u003e\n  \u003cli\u003eLED display enables visual damper position verification during checkout\u003c\/li\u003e\n  \u003cli\u003eNylon bushings provide quieter operation and extended motor service life\u003c\/li\u003e\n  \u003cli\u003eOverlapping blade design rated at 97% leak-proof for accurate airflow isolation\u003c\/li\u003e\n  \u003cli\u003eTool-free quick-connect terminal block eliminates wire nuts and simplifies wiring\u003c\/li\u003e\n  \u003cli\u003eMotor is UL listed and NEMA Class 2 certified\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to integrate with the EWC Controls Ultra-Zone zoning system.

Disconnect power to the air handler and zone control board before wiring the damper. Ensure duct sizing matches the 14 x 10 inch damper opening before securing the unit in place. Follow the zoning control manufacturer wiring diagram and applicable local mechanical codes during termination at the control board.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Size\u003c\/strong\u003e: 14 x 10 inches\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\u003eMotor Torque\u003c\/strong\u003e: 17 inch-pounds\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\u003eLength\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.9 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-14X10-MA15S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51346528698674,"sku":"END-14X10-MA15S","price":282.15,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555024.webp?v=1782082814","url":"https:\/\/voomisupply.com\/products\/ewc-controls-end-14x10-ma15s-motorized-zone-damper-14x10","provider":"Voomi Supply","version":"1.0","type":"link"}
