Bypass dampers relieve excess static pressure by redirecting supply air back to the return side of the system when zone dampers close off portions of the duct network. This prevents over-pressurization, reduces blower strain, and protects heat exchangers from low-airflow conditions. At 7 pounds, the 6110 is a solid, installation-ready unit suited for installation by licensed HVAC technicians in both new construction and retrofit zoning projects.\u003c\/p\u003e\u003cp\u003eThis bypass damper is used in residential and light commercial forced-air zoning systems where multiple zone dampers create variable static pressure conditions. It is typically installed in the supply plenum or a dedicated bypass duct connecting the supply trunk to the return air plenum. The mechanical design means it operates without an external actuator or control wiring, opening and closing in direct response to duct pressure differential. This makes it a straightforward solution for single-zone pressure relief in multi-zone systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMechanical operation responds passively to duct static pressure with no actuator or control wiring required\u003c\/li\u003e\n\u003cli\u003eRound design fits standard round duct and plenum collar connections\u003c\/li\u003e\n\u003cli\u003eRelieves excess static pressure to protect blowers and heat exchangers in zoned systems\u003c\/li\u003e\n\u003cli\u003eSuitable for new construction and retrofit multi-zone HVAC installations\u003c\/li\u003e\n\u003cli\u003eSubstantial construction at 7 pounds for durable in-duct service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style bypass damper for use in residential and light commercial forced-air zoning systems requiring passive mechanical pressure relief in round duct configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician following applicable mechanical codes. Shut down the air handler and de-energize the system at the disconnect before cutting into ductwork or plenum. The bypass duct connecting supply to return must be sized and routed to avoid short-circuiting conditioned air near the return intake. Seal all duct connections with approved mastic or foil tape per local code requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper Style\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Mechanical Bypass\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: 6110\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RESEARCH PRODUCTS","offers":[{"title":"Default Title","offer_id":51138755461426,"sku":"6110","price":100.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532904.jpg?v=1778263039","url":"https:\/\/voomisupply.com\/products\/research-products-6110-round-mechanical-bypass-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
