Flexible ventilation duct airRoxy FLEX 100 — flexible round air duct, model 03-600

Flexible ventilation duct airRoxy FLEX 100 (model 03-600) is a round, flexible air duct designed for ventilation and air extraction systems. The duct provides a pliable connection between fans, vents and fixed ductwork where rigid ducts are impractical. Its compact diameter and flexibility make it suitable for routing air in confined spaces such as bathrooms, kitchens and light commercial installations that require a bendable conduit to manage airflow.

Advantages

The flexible construction allows easy bending and positioning without special tools, reducing installation time in retrofit and new-build projects. The smooth inner surface supports uninterrupted airflow and reduces noise compared with more corrugated alternatives. Lightweight materials simplify handling and reduce load on mounting points, while compatibility with common round fittings and clamps enables straightforward integration with existing ventilation components.

Suitable for

• Bathroom extractor fan connections
• Kitchen hood or venting paths in limited spaces
• Short runs between ventilation devices and ductwork
• Retrofit projects where rigid ducts cannot be used
• Light commercial ventilation and air extraction tasks

Key specifications

• Round, flexible duct shape with compact nominal diameter suitable for standard small-ventilation fittings
• Designed for air supply and exhaust applications in residential and light commercial environments
• Flexible construction to accommodate bends and changes in direction without rigid fittings
• Lightweight material for easier handling and reduced support requirements
• Compatible with common round clamps and connectors for sealed joints

How to use

Measure the required run and cut the flexible duct to length using appropriate tools, ensuring clean, square ends. Fit the duct over the fan spigot or vent outlet and secure with a suitable clamp or connector to maintain an airtight connection. Avoid sharp kinks and excessive compression; allow gentle curves to preserve airflow. When connecting to rigid ductwork, use compatible adapters and seal joints with tape or sealant approved for ventilation use. Support longer runs at regular intervals to prevent sagging and maintain consistent airflow.

Usage recommendations

For optimal performance, keep runs as short and straight as possible, with smooth bends rather than sharp angles. Inspect connections periodically for secure clamps and any signs of wear or damage, and replace the flexible duct if it becomes punctured, excessively flattened or degraded.
