Flexible duct SpiroFlex Rura black 160 mm, 1 m — ventilation hose

SpiroFlex Rura black flexible duct with a 160 mm diameter and 1 m length is designed for ventilation and air extraction systems in residential and light commercial settings. This ventilation hose provides a flexible connection between ventilation elements such as ducts, fans and vents, allowing effective routing of supply and exhaust air where rigid ducts are impractical. The black exterior reduces light transmission and helps conceal the duct when visible in installations.

Advantages

The flexible construction allows bending and compression to adapt to limited spaces and non-linear routes without loss of airflow performance. Made for compatibility with standard 160 mm connections, the hose simplifies installation and replacement. Its lightweight design eases handling and reduces strain on mounting points. The smooth internal profile supports airflow while limiting turbulence and particulate accumulation during normal operation.

Suitable for

• Connecting inline fans to ventilation ducts in bathrooms and kitchens
• Temporary or permanent routing of exhaust air from small commercial premises
• Extending or connecting HVAC components where rigid ducting is not feasible
• Use in renovation projects to adapt existing ventilation runs

Key specifications

• Inner diameter: 160 mm
• Length: 1 m
• Color: black
• Construction: flexible corrugated ventilation hose suitable for bending and compression
• Compatibility: fits standard 160 mm ventilation connections and fittings

How to use

Measure the required length and ensure the 160 mm connection points are clean and free of sharp edges. Slide the hose onto the duct or fan flange until a secure fit is achieved, and use appropriate clamps or collars to fasten both ends to prevent air leaks. Avoid overstretching the hose beyond its designed length; compressing or bending should be done within reasonable radii to maintain airflow efficiency. For permanent installations, check that supports or hangers are provided to prevent sagging.

Usage recommendations

Inspect the flexible duct periodically for tears, punctures or excessive wear, especially in high-moisture environments. Where possible, minimize sharp bends and maintain short, smooth runs to preserve airflow and reduce noise. For applications requiring fire resistance or specific hygiene standards, verify material suitability and local regulations before installation.
