SpiroFlex ventilation duct RURA WENT.AL. 80 L-2,7MB 0,1mm – flexible aluminum air duct, Ø80 mm, length 2.7 m, wall 0.1 mm

SpiroFlex ventilation duct RURA WENT.AL. 80 L-2,7MB 0,1mm is a flexible aluminum air duct with a nominal diameter of 80 mm, a total length of 2.7 m and a wall thickness of 0.1 mm. It is designed for air extraction and distribution in residential and light-commercial HVAC installations and provides a lightweight, bendable connection between vents, fans and duct transitions. The duct’s thin-wall aluminum construction makes it suitable for confined spaces and retrofit work where flexibility and easy routing are required.

Advantages

The flexible aluminum construction offers low weight and good formability while maintaining airflow integrity for short duct runs. Its 0.1 mm wall thickness balances pliability and sufficient mechanical stability for non-pressurized ventilation applications. The 80 mm diameter is compatible with common small ventilation fans and terminal fittings, enabling straightforward connections without complex adapters. Longitudinal flexibility allows routing around obstacles and fitting into tight cavities.

Suitable for

• Connecting small bathroom or kitchen exhaust fans to external vents
• Flexible transitions between rigid ducts and terminal grilles
• Retrofit ventilation in apartments, utility rooms and crawl spaces
• Temporary ventilation setups and inspection-accessible runs

Key specifications

• Material: flexible aluminum
• Nominal diameter: 80 mm
• Total length: 2.7 m
• Wall thickness: 0.1 mm
• Construction: thin-wall, corrugated for flexibility

How to use

Measure and cut the flexible duct to the required length using tin snips or shears, leaving enough overlap for secure connections. Slide the duct over the fan outlet or rigid duct stub and secure with a suitable clamp, zip tie or foil tape rated for ventilation use. Avoid excessive compression or kinking; maintain a smooth curvature to reduce airflow resistance. For exterior penetrations, ensure the duct is routed to minimize exposure to sharp edges and secured to prevent sagging.

Usage recommendations

Use this flexible aluminum duct for short, unpressurized exhaust or supply runs where flexibility and compact routing are priorities. Do not use for high-pressure duct systems or where building codes require rigid ducting. Inspect connections periodically for damage or loosening, and replace the duct if punctured, severely creased, or otherwise compromised.
