It features an aluminum frame and blade construction with a power-closed, spring-open motor that operates at 24 volts AC at 60 Hz, drawing 6 watts and 12 volt-amps. The 2-wire electrical connection simplifies wiring to zone control panels and thermostats. Bottom mounting orientation suits typical duct branch applications. The damper is rated for a maximum static pressure of 1 inch water column (in-WC), making it appropriate for residential and light commercial zoning installations. A licensed HVAC technician or sheet metal contractor typically handles procurement and installation.\u003c\/p\u003e\u003cp\u003eThis damper is used in ducted forced-air systems where independent temperature control is required across multiple zones. The spring-open fail-safe design ensures airflow is restored if power is lost, which is a common requirement in residential zoning layouts. Bottom-mount configuration fits standard rectangular duct branch takeoffs. The 2-wire connection interfaces directly with most 24-volt zone control boards, reducing wiring complexity during new construction or retrofit zoning projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePower-closed, spring-open motor provides fail-safe airflow on power loss\u003c\/li\u003e\n\u003cli\u003e24 VAC at 60 Hz motor — compatible with standard low-voltage HVAC control circuits\u003c\/li\u003e\n\u003cli\u003eAluminum frame and blade construction for lightweight, corrosion-resistant performance\u003c\/li\u003e\n\u003cli\u003e2-wire electrical connection simplifies zone board wiring\u003c\/li\u003e\n\u003cli\u003eBottom mounting orientation for standard rectangular duct branch installations\u003c\/li\u003e\n\u003cli\u003eRated to 1 in-WC maximum static pressure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for residential and light commercial forced-air zoning systems using 24-volt control circuits and rectangular duct configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician or licensed sheet metal contractor in accordance with local mechanical codes and NFPA 90A\/90B guidelines. Shut down the air handler and de-energize the 24-volt control circuit before wiring or mounting the damper. Verify duct dimensions and static pressure conditions do not exceed the 1 in-WC rating before commissioning. Seal the damper flange to the duct collar with approved foil tape or mastic to prevent air bypass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 Apparent Power\u003c\/strong\u003e: 12 volt-amps\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: Bottom\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 6813\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RESEARCH PRODUCTS","offers":[{"title":"Default Title","offer_id":51138806481202,"sku":"6813","price":178.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532994.jpg?v=1778263697","url":"https:\/\/voomisupply.com\/products\/research-products-6813-rectangular-zone-damper-24v","provider":"Voomi Supply","version":"1.0","type":"link"}
