The integrated actuator opens and closes the damper blade automatically, diverting excess conditioned air back to the return side of the system when zone dampers close. This prevents static pressure buildup that can damage equipment and degrade comfort. At 8 pounds and sized for a 20x8 inch duct opening, it is a robust solution suited to residential and light commercial zoning applications. Licensed HVAC technicians typically supply and install this component during zoning system commissioning or retrofit work.\u003c\/p\u003e\n\u003cp\u003eThe EB-2008 is used in forced-air zoning systems where multiple zone dampers control airflow to individual areas of a building. When one or more zones close, excess supply air pressure must be relieved to protect the air handler or furnace blower. This bypass damper mounts between the supply plenum and the return plenum or a return duct, automatically bypassing air to balance system pressure. It is appropriate for residential and light commercial installations where a 20x8 inch bypass opening matches the required bypass capacity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMotorized actuator provides automatic bypass operation without manual intervention\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty construction rated for continuous cycling in active zoning systems\u003c\/li\u003e\n  \u003cli\u003eFits a 20x8 inch duct opening for proper airflow bypass capacity\u003c\/li\u003e\n  \u003cli\u003eCompact package dimensions of 10 inches wide, 27 inches tall, and 8 inches deep\u003c\/li\u003e\n  \u003cli\u003e8-pound shipping weight indicates solid, durable damper body construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style motorized bypass damper for forced-air zoning systems requiring a 20x8 inch bypass opening in residential or light commercial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Shut down and lock out the air handler or furnace before beginning duct work or wiring. The damper must be wired to the zone control board according to the zone controller manufacturer's low-voltage wiring diagram. Follow all applicable mechanical and electrical codes, including local adoptions of the International Mechanical Code and the National Electrical Code, when routing and connecting control wiring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Size\u003c\/strong\u003e: 20x8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 27 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Depth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8 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: IO HVAC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EB-2008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67948467388722,"sku":"EB-2008","price":414.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c48755c782494323bc8b0480a1692035_2d6a4608-c708-48d6-9c65-92f48b755a97.png?v=1791664589","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-eb-2008-motorized-bypass-damper-20x8","provider":"Voomi Supply","version":"1.0","type":"link"}
