It measures 20 inches by 10 inches and operates on 24 VAC single-phase power at 50\/60 Hz, drawing 1.5 amps. Constructed from aluminum with a silver finish, the damper features a heavy-duty frame, nylon bushings for quieter operation, and overlapping blades that deliver a 97 percent leak-proof rating. The integrated motor provides a manual gear release and is driven with sufficient torque for reliable open and close cycling. Built-in LEDs give installers a quick visual confirmation of damper position and fail-safe status. The motor is UL Listed. Licensed HVAC technicians typically perform installation in residential and light-commercial duct systems.\u003c\/p\u003e\n\u003cp\u003eThe END-20X10-MA15S is intended for use in HVAC zoning applications where individual zones require independent airflow control. It is rated for heat pump compatible systems and supports network zoning configurations. The damper operates across an ambient temperature range of 0 degrees F to 140 degrees F and is rated to a maximum temperature of 185 degrees F, making it suitable for both heating and cooling zone control. The motor is always mounted on the second dimension specified, which simplifies orientation planning during rough-in. A quick-connecting terminal block eliminates wire nuts and speeds up field wiring.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeavy-duty aluminum frame with face plate mounting for fast duct installation\u003c\/li\u003e\n  \u003cli\u003eNylon bushings reduce operational noise for quieter zone control\u003c\/li\u003e\n  \u003cli\u003e3-wire power-open\/power-closed operation with manual gear release\u003c\/li\u003e\n  \u003cli\u003eLED indicators provide instant visual confirmation of damper position and fault status\u003c\/li\u003e\n  \u003cli\u003e97 percent leak-proof rating via overlapping blade design\u003c\/li\u003e\n  \u003cli\u003eHeat pump compatible and network zoning ready\u003c\/li\u003e\n  \u003cli\u003eUL Listed motor; manufactured in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with forced-air HVAC zoning systems requiring a 20-inch by 10-inch rectangular motorized damper.

Disconnect and lock out power to the air handler and zone control panel before beginning any wiring or duct work. The motor is always positioned on the second dimension specified when ordering, so confirm orientation before cutting the duct opening. Use the quick-connecting terminal block for field wiring connections and verify LED status indicators for proper damper travel before closing up the duct.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 20 inches x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 24 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 1.5 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 50\/60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Type\u003c\/strong\u003e: Zone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmbient Temperature Range\u003c\/strong\u003e: 0 degrees F to 140 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 185 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Face plate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat Pump Compatible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNetwork Zoning\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL Listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 24 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: 7.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\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-20X10-MA15S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51347617972530,"sku":"END-20X10-MA15S","price":299.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555035.webp?v=1782109697","url":"https:\/\/voomisupply.com\/products\/ewc-controls-end-20x10-ma15s-motorized-zone-damper-20x10","provider":"Voomi Supply","version":"1.0","type":"link"}
