It features an aluminum frame and blade construction with a power-closed, spring-open motor that operates on 24 VAC at 60 Hz, drawing 6 watts and 12 volt-amperes. The 2-wire electrical connection simplifies wiring to zone control boards. Side mounting accommodates standard duct installations where access is needed along the damper body. The unit is rated for a maximum static pressure of 1 inch water column (in-WC). Licensed HVAC technicians install this damper as part of a multi-zone control system to regulate conditioned air distribution to individual building zones.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for residential and light commercial forced-air zoning applications. It installs in rectangular duct sections where zone-by-zone temperature control is required. The spring-open, power-closed design means the damper defaults to the open position on loss of power, which is a common fail-safe configuration in zoning systems. It is compatible with 24-volt zone control panels that use a standard 2-wire damper output. HVAC technicians typically integrate this unit with a thermostat-driven zone controller to open and close supply ducts based on individual zone demand.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePower-closed, spring-open motor provides automatic fail-safe open position on power loss\u003c\/li\u003e\n  \u003cli\u003e24 VAC at 60 Hz motor operation integrates with standard low-voltage zone control panels\u003c\/li\u003e\n  \u003cli\u003e2-wire electrical connection reduces wiring complexity at the zone controller\u003c\/li\u003e\n  \u003cli\u003eAluminum frame and blade construction for lightweight, corrosion-resistant duct installation\u003c\/li\u003e\n  \u003cli\u003eSide mounting configuration for accessible installation in rectangular duct runs\u003c\/li\u003e\n  \u003cli\u003e1 in-WC maximum pressure rating suitable for residential and light commercial systems\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 rectangular duct zoning systems using 24-volt, 2-wire damper control outputs.\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 applicable mechanical codes. Disconnect and lock out power to the air handler and zone control panel before wiring or mounting the damper. The damper must be installed in the correct airflow orientation as indicated on the unit body. Do not exceed the rated 1 in-WC static pressure in the duct system where this damper is installed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangular\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 watts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor VA Rating\u003c\/strong\u003e: 12 volt-amperes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: Power Closed, Spring Open\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElectrical Connection\u003c\/strong\u003e: 2-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 1 in-WC Maximum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrame and Blade Material\u003c\/strong\u003e: Aluminum\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: 6737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RESEARCH PRODUCTS","offers":[{"title":"Default Title","offer_id":51138510324018,"sku":"6737","price":199.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532979.jpg?v=1778258037","url":"https:\/\/voomisupply.com\/products\/research-products-6737-rectangular-zone-damper-24v","provider":"Voomi Supply","version":"1.0","type":"link"}
