## Long description

SpiroFlex FLEX 115 mm aluminium round ventilation duct (model AL.115) is a lightweight, corrosion-resistant aluminium ducting solution intended for air distribution and extraction in residential and light-commercial HVAC systems. Its 115 mm internal diameter is suitable for branch runs, connections to fans, grilles and fittings where a compact circular duct is required. The construction provides flexibility for installation in constrained spaces and is suitable for repairs, extensions or new ductwork where a rigid line is not necessary.
Advantages
The aluminium material offers low weight and natural resistance to corrosion, which simplifies handling and reduces long-term degradation in typical indoor environments. The round cross-section and standard diameter enable compatible connections with common circular ventilation components. Flexibility in the duct allows easier routing through confined or irregular cavities compared with rigid ductwork and shortens installation time where bending or minor adjustments are needed.
Suitable for
Residential ventilation supply and exhaust runs
Connecting smaller extractor fans and inline fans
Kitchen and bathroom exhaust systems
Repairs and extensions of existing ventilation ducts
Light-commercial ventilation installations with compact routing needs
Key specifications
Shape: round cross-section
Nominal internal diameter: 115 mm
Material: aluminium (corrosion-resistant, lightweight)
Typical applications: air distribution and extraction in HVAC systems
Compatibility: designed for connection to circular fans, grilles and duct fittings of corresponding diameter
How to use
Measure the required duct length and cut the aluminium duct to size using appropriate tools, taking care to deburr cut edges. Fit the duct between components and secure connections with compatible clamps, collars or sealing tape to ensure airtight joints. When routing, avoid sharp kinks and provide gentle bends to maintain airflow efficiency. Install supports or fixings at regular intervals to prevent sagging and to maintain alignment with other duct components.
Usage recommendations
Use the duct in indoor, non-corrosive environments and avoid exposure to aggressive chemicals or prolonged moisture. For best airflow performance, minimize abrupt bends and long unsupported runs. For installations serving higher airflow or high-temperature applications, verify compatibility with system requirements and consider using appropriately rated components.
