It is designed for HVAC zoning systems and controls airflow by opening and closing on command via a 3-wire power-open\/power-closed motor. The motor delivers 17 inch-pounds of torque and includes a manual gear release, fail-safe LED indicators for quick diagnostic checks, and a UL-listed, NEMA Class 2 certified drive assembly. Nylon bushings reduce noise during operation. The unit carries a 97% leak-proof rating, achieved through overlapping blades and a firm positive-off motor stop. HVAC technicians and zoning system installers are the primary trade professionals who specify and install this damper.\u003c\/p\u003e\n\u003cp\u003eThe END-8X10-MA15S fits into rectangular HVAC ductwork measuring 8 inches by 10 inches. It is intended for use in residential zoning applications, typically paired with a compatible Ultra-Zone zoning control system. An easy-access terminal block with quick-connect terminals eliminates the need for wire nuts, streamlining field wiring during installation. The LED display on the motor head allows the technician to confirm damper position and verify operation at checkout without additional test equipment. The sturdier frame design is built to reduce installation time and improve long-term reliability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-wire power-open\/power-closed motor operation for reliable zone control\u003c\/li\u003e\n  \u003cli\u003e17 inch-pounds of motor torque with manual gear release for service access\u003c\/li\u003e\n  \u003cli\u003eFail-safe LED indicators for fast on-site diagnostics\u003c\/li\u003e\n  \u003cli\u003e97% leak-proof rating via overlapping blade design and positive-off motor\u003c\/li\u003e\n  \u003cli\u003eNylon bushings for quieter operation and reduced long-term wear\u003c\/li\u003e\n  \u003cli\u003eQuick-connect terminal block eliminates wire nuts and speeds field wiring\u003c\/li\u003e\n  \u003cli\u003eUL-listed and NEMA Class 2 certified motor assembly\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. Fits 8-inch by 10-inch rectangular duct openings.

Power to the air handler and zoning control panel must be shut off before mounting the damper or making any wiring connections. Use the quick-connect terminal block for all low-voltage control wiring, and confirm damper blade travel and LED status indicators before restoring power and closing the system. Follow local mechanical codes and the zoning control manufacturer wiring diagrams for proper zone sequencing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 8 x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Operation\u003c\/strong\u003e: 3-wire power-open\/power-closed\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: 17 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: 4.6 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-8X10-MA15S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51345168269618,"sku":"END-8X10-MA15S","price":267.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555096.webp?v=1782050995","url":"https:\/\/voomisupply.com\/products\/ewc-controls-end-8x10-ma15s-nd-series-motorized-zone-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
