It provides automated airflow control by opening and closing on demand from a zone controller or thermostat signal, allowing precise delivery of conditioned air to designated zones. The damper measures 8 x 18 inches in duct size and is built for reliable integration into residential and light commercial zoning applications. Licensed HVAC technicians install this unit as part of a complete zone control system to balance comfort and energy efficiency across multiple areas of a building.\u003c\/p\u003e\n\u003cp\u003eThis motorized damper is suited for rectangular duct installations in single-family residential and light commercial forced-air systems. It is typically installed in supply trunk lines or branch ducts where zone-by-zone airflow regulation is required. The END-8X18-MA15S fits 8 x 18 inch duct openings and works within low-voltage zone control systems. It is commonly used in new construction and retrofit zoning projects where independent room or area temperature control is the goal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMotorized actuation for automated open and close airflow control\u003c\/li\u003e\n  \u003cli\u003eFits 8 x 18 inch rectangular duct openings\u003c\/li\u003e\n  \u003cli\u003eDesigned for integration with low-voltage zone control systems and thermostats\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for tight plenum and duct chase installations\u003c\/li\u003e\n  \u003cli\u003eWeighs 6.3 pounds for straightforward single-technician handling during install\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style motorized zone damper replacement or new-installation component for 8 x 18 inch rectangular duct systems in residential and light commercial forced-air zoning setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with zoned forced-air systems. Disconnect power to the air handler and zone control panel before beginning any wiring or duct work. Follow NEC requirements for low-voltage control wiring and verify the damper actuator signal type matches the zone controller output before energizing. Do not exceed the rated duct size or force the damper blade during installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Size\u003c\/strong\u003e: 8 x 18 inches\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: 6.3 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-8X18-MA15S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51347573408050,"sku":"END-8X18-MA15S","price":279.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555022.webp?v=1782108908","url":"https:\/\/voomisupply.com\/products\/ewc-controls-end-8x18-ma15s-motorized-damper-8x18","provider":"Voomi Supply","version":"1.0","type":"link"}
