Flexible ventilation duct airRoxy FLEX 150 — ø150 mm flexible air duct for ventilation systems

Flexible ventilation duct airRoxy FLEX 150 — ø150 mm flexible air duct for ventilation systems is a flexible conduit designed for use in residential and commercial ventilation installations. It connects fans, grilles and rigid ductwork to allow air transport where straight ducts are impractical. The duct's ø150 mm diameter accommodates common fan outlets and diffusers and its corrugated body permits bending and routing in confined or irregular spaces while maintaining airflow for both supply and exhaust applications.

Advantages

The airRoxy FLEX 150 combines flexibility with a compact profile that simplifies installation in tight spaces. Its corrugated construction provides good bendability without the need for special tools and helps absorb small misalignments between components. The product is lightweight and easy to handle, which reduces installation time and effort. It is suitable for both temporary and permanent connections in ventilation systems, offering a practical solution when rigid ducts cannot be used.

Suitable for

• Connecting axial or centrifugal fans with ø150 mm outlets
• Routing ventilation between rooms, through attics, crawl spaces and false ceilings
• Exhausting moisture and odors from kitchens, bathrooms and utility rooms
• Supply air distribution in small commercial and residential systems

Key specifications

• Nominal internal diameter: 150 mm
• Flexible corrugated construction for easy bending and routing
• Lightweight and easy to cut to required length
• Suitable for both supply and exhaust air applications
• Compatibility with standard ø150 mm ventilation fittings and clamps

How to use

Measure the distance between connection points and cut the flexible duct to the required length using an appropriate cutting tool. Slide one end over the fan outlet or duct collar and secure it with a suitable clamp or fastening method; repeat at the opposite end. Avoid sharp kinks and keep bends gradual to minimise airflow resistance. Ensure connections are sealed and supported so the duct is not bearing structural loads or exposed to sustained compression that could reduce airflow.

Usage recommendations

For optimal performance, maintain smooth, gradual bends and avoid compressing the duct beyond its designed profile. Use appropriate clamps or fastening systems rated for ventilation ducting, and provide periodic inspection to ensure connections remain tight and unobstructed. Select the FLEX 150 for installations where a flexible, easy-to-route duct is required for ø150 mm systems.
