Flexible ventilation duct airRoxy FLEX 80 — Ø80 mm flexible air duct

Flexible ventilation duct airRoxy FLEX 80 — Ø80 mm flexible air duct is designed for residential and light commercial ventilation systems. The conduit is constructed to allow bending and routing in confined or irregular spaces while maintaining an internal diameter of 80 mm for consistent airflow. It is suitable for connecting axial fans, wall vents and air inlets where a flexible connection simplifies installation and alignment.

Advantages

This flexible air duct combines bendability with a stable internal profile to reduce airflow disruption and resistance. Its construction allows quick positioning and adaptation to existing ductwork or directly to ventilation equipment without the need for extensive fittings. The lightweight design facilitates handling and reduces installation time while the durable materials enable repeated bends without immediate deformation.

Suitable for

• Connecting small exhaust or supply fans in bathrooms and kitchens
• Ventilation connections in utility rooms, crawl spaces, and attics
• Temporary or permanent routing where rigid ducts are impractical

Key specifications

• Nominal internal diameter: 80 mm
• Flexible spiral construction for bendable routing
• Lightweight and low-profile conduit suitable for confined spaces
• Compatible with standard Ø80 mm fittings and clamping methods

How to use

Measure the required length and cut the flexible duct to size using appropriate tools, ensuring a clean, square cut to preserve airflow. Slide the duct over the fan outlet, vent or connector so the internal spiral seats correctly, then secure with a hose clamp or metal tape to ensure an airtight connection. Avoid sharp kinks and maintain smooth bends to reduce pressure losses; if a long run is needed, support the duct at intervals to prevent sagging.

Usage recommendations

For optimal performance, use the airRoxy FLEX 80 in straight or gently curved runs and avoid compressing the duct more than necessary. Verify compatibility with the fan or vent's Ø80 mm interface and use appropriate clamps or collars to achieve a secure, low-leak connection. For installations in areas with higher temperatures or chemical exposure, consult local standards and choose materials accordingly.
