Lambro Industries 310F Semi-rigid Aluminum Duct 8 in X 8 Ft

Product Description

The LAMBRO INDUSTRIES 310F is a semi-rigid aluminum duct designed for residential HVAC and kitchen venting applications that require durable, low-leakage airflow management. Constructed from aluminum with a triple-lock seam design, this duct measures 8 inches in diameter and 8 feet in length. The semi-rigid construction holds its shape under typical installation conditions while remaining flexible enough to navigate offsets and transitions. Licensed HVAC technicians and kitchen ventilation installers rely on this type of duct to connect range hoods, exhaust fans, and air handlers to exterior termination points with minimal air leakage and reliable structural integrity.

This duct is suited for general HVAC venting and kitchen exhaust applications in residential settings. It is commonly used to route conditioned or exhaust air from range hoods, bathroom fans, dryer transitions, and similar appliances to an exterior vent cap. The 8-inch diameter accommodates higher-volume exhaust systems typical of commercial-grade residential range hoods. The 8-foot length provides sufficient run for most straight or near-straight venting scenarios without requiring a coupling.

Key Features

• Semi-rigid aluminum construction maintains duct shape and resists crushing during and after installation
• Triple-lock seam design reduces air leakage at the duct wall for improved system efficiency
• 8-inch diameter supports higher-volume kitchen and HVAC exhaust applications
• 8-foot length suitable for standard single-run venting without additional fittings
• Aluminum material resists corrosion and withstands typical exhaust temperature ranges

Compatibility

Designed as an OEM-style replacement and new-installation semi-rigid aluminum duct for residential HVAC and kitchen venting systems requiring an 8-inch diameter exhaust duct connection.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed contractor in accordance with local mechanical codes and manufacturer guidelines. Power down or disconnect the associated appliance or air handler before making duct connections. Secure all joints with approved foil tape or approved duct connectors — do not use standard cloth-backed duct tape on aluminum semi-rigid duct. Minimize bends and keep total duct run within the equivalent length limits specified by the connected appliance manufacturer.
