Aluminium Duct Pipe Prodmax Aluflex 120 — flexible aluminium tubing, model FLEX/120

Prodmax Aluflex 120 is a flexible aluminium duct pipe designed for ventilation and air distribution systems. The FLEX/120 model combines a lightweight, corrosion-resistant aluminium construction with a flexible corrugated profile that facilitates routing through confined spaces and around obstacles. It is intended for use as a connector between fans, air handlers, hoods and other ventilation components where a flexible, conductive duct is required.

Advantages

The aluminium material offers resistance to rust and reduced weight compared with steel alternatives while maintaining adequate mechanical strength for typical ventilation tasks. The flexible corrugated design enables tight bending radii and simpler installation in retrofit and new-build projects. Smooth internal surface treatment and metallic continuity support conductive and anti-static applications, and the product is compatible with standard duct clamps and collars for secure connections.

Suitable for

• HVAC ducting in residential and commercial buildings
• Exhaust venting for kitchens, bathrooms and small workshops
• Connection between fans, air handlers and rigid ductwork
• Temporary or permanent installations requiring flexible routing

Key specifications

• Material: aluminium construction for corrosion resistance and low weight
• Form: flexible corrugated tubing allowing bending and compression
• Intended use: ventilation and air distribution systems, exhaust connections
• Compatibility: connects to standard circular duct fittings using clamps or collars
• Conductivity: metallic continuity suitable for conductive ducting applications

How to use

Measure the required length and cut the Aluflex 120 to size using appropriate tools for metal tubing, ensuring clean, deburred edges. Slide the duct over the connecting collar or flange and secure with a hose clamp, crimp ring or zip tie rated for ventilation use. Maintain gentle bends rather than sharp kinks to preserve airflow and avoid compressing the duct excessively; where possible, support the duct at regular intervals to prevent sagging. Ensure joints are sealed appropriately with foil tape or mastics when an airtight connection is required.

Usage recommendations

Use the duct in temperature and chemical environments compatible with aluminium; avoid continuous exposure to highly acidic or alkaline atmospheres. For applications where airtightness and minimal leakage are critical, pair the Aluflex 120 with appropriate sealing materials and rigid transitions. Inspect connections periodically and replace damaged sections to maintain ventilation performance.
