Constructed from aluminum, this flex duct ships compressed for compact storage and easier job-site handling. At 4 inches in diameter and 8 feet in length, it suits a wide range of ducted exhaust runs where a lightweight, corrosion-resistant connector is required. Licensed HVAC technicians and sheet metal installers typically specify this type of flex duct for dryer exhaust, bathroom exhaust fans, and inline fan connections where rigid duct transitions are not practical.\u003c\/p\u003e\u003cp\u003eThis duct is suited for residential and light commercial ventilation installations. Common applications include connecting exhaust fans to exterior terminations, routing dryer exhaust from appliance to wall cap, and bridging rigid duct runs to equipment flanges. The 4-inch diameter is a standard size across many exhaust fan and dryer installations. The compressed ship format allows multiple units to be stored or transported without significant bulk, making it a practical stock item for service vans and supply rooms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum construction provides corrosion resistance for exhaust and ventilation service\u003c\/li\u003e\n\u003cli\u003e4-inch diameter matches common exhaust fan and dryer exhaust fitting sizes\u003c\/li\u003e\n\u003cli\u003e8-foot length provides sufficient run for most residential exhaust connections\u003c\/li\u003e\n\u003cli\u003eShips in compressed form for compact storage and ease of transport\u003c\/li\u003e\n\u003cli\u003eLightweight material simplifies overhead and wall-cavity installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use flexible duct connector for 4-inch exhaust fan outlets, dryer exhaust ports, and inline fan installations in residential and light commercial ventilation systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or qualified installer. Power down any connected fan or appliance at the breaker before disconnecting or attaching flex duct. Secure both ends with approved clamps or foil tape rated for the application — never use standard duct tape on exhaust runs. Follow local mechanical codes and manufacturer guidelines for maximum flex duct run length and bend radius to maintain proper airflow.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 8 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShip Condition\u003c\/strong\u003e: Compressed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 9 per case\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LAMBRO INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 302L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LAMBRO INDUSTRIES","offers":[{"title":"Default Title","offer_id":51525203853618,"sku":"302L","price":146.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8d04216025b9c6d48572d31a422886d_3194ea19-f23f-4e5b-bddf-8e10f55ab6bf.jpg?v=1785467112","url":"https:\/\/voomisupply.com\/products\/lambro-industries-302l-aluminum-flexible-duct-4in-x-8ft","provider":"Voomi Supply","version":"1.0","type":"link"}
