It features an aluminum frame and blade construction with a galvanized finish, providing durability in forced-air duct applications. The integrated synchronous motor operates on 24 VAC at 60 Hz, drawing 6 watts and 12 VA. The damper is power closed and spring open, meaning it defaults to the open position on a power loss — an important failsafe characteristic for zoning installations. At 11-7\/8 inches wide and 11.813 inches in height, this square damper fits standard duct openings in that size range. Licensed HVAC technicians typically handle the installation and wiring of this component.\u003c\/p\u003e\n\u003cp\u003eThe 6743 is suited for residential and light commercial forced-air zoning applications where independent temperature control of multiple zones is required. Its side-mounting configuration fits standard duct installations, and its 1 inch water column pressure rating supports typical residential and light commercial static pressure conditions. The synchronous motor design integrates cleanly with 24-volt zone control boards and thermostats common in multi-zone HVAC systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum frame and blade construction with galvanized finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePower closed, spring open motor operation provides failsafe open position on power loss\u003c\/li\u003e\n  \u003cli\u003e24 VAC synchronous motor at 60 Hz, 6 W, 12 VA for compatibility with standard low-voltage zoning controls\u003c\/li\u003e\n  \u003cli\u003eSquare shape at 11-7\/8 x 11.813 inches fits standard residential and light commercial duct openings\u003c\/li\u003e\n  \u003cli\u003e1 inch water column pressure rating suitable for residential and light commercial static pressure requirements\u003c\/li\u003e\n  \u003cli\u003eSide-mounting design for straightforward duct installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for residential and light commercial forced-air HVAC zoning systems requiring a square motorized damper at approximately 11-7\/8 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with low-voltage zoning systems and local mechanical codes. Disconnect and lock out power to the air handler and zone control board before mounting or wiring the damper. The 24-volt motor connections must be made to a compatible zone controller or damper control board — verify control board specifications before wiring. Do not force the blade manually while the motor is energized.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum Frame and Blade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 11-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 11.813 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: Synchronous, Power Closed, Spring Open\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Voltage\u003c\/strong\u003e: 24 VAC at 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Power\u003c\/strong\u003e: 6 W, 12 VA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 1 inch WC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Side\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: RESEARCH PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6743\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RESEARCH PRODUCTS","offers":[{"title":"Default Title","offer_id":51138391277874,"sku":"6743","price":185.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532965.jpg?v=1778255070","url":"https:\/\/voomisupply.com\/products\/research-products-6743-zone-damper-with-motor-square","provider":"Voomi Supply","version":"1.0","type":"link"}
