125mm Round Ducting Pipe — 1 Metre
This is the standard 1 metre straight section of 125mm round rigid ducting pipe, suitable for cooker hood installations with motor speeds up to 750m³/hr. It is part of the Luxair 5" push-fit airtight ducting system.
Why Rigid Round Ducting Outperforms Flexible Aluminium Pipe
Rigid round ducting is significantly more efficient than flexible aluminium pipe. Flexible aluminium tube has a corrugated interior surface that creates turbulence and resistance in the airflow, reducing extraction performance — particularly over longer duct runs. The smooth interior walls of rigid round ducting allow air to travel freely with minimal resistance, delivering consistently higher extraction rates from the same motor. For any installation where rigid ducting can be fitted, it is always the preferred choice over flexible aluminium pipe.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:
- Below 450m³/hr → 100mm (4") ducting
- 450–750m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2,000m³/hr → 150mm (6") or 200mm (8") ducting
The 5" Push-Fit System
This pipe is part of the Luxair 125mm (5") push-fit airtight ducting range. The system combines 125mm round ducting and 150mm × 70mm flat rectangular ducting — both formats carry equivalent airflow rates and are fully interchangeable within the system. All components connect by push-fit for a patent-protected airtight seal with no ducting tape, adhesive, or clips required. Suitable for kitchen, bathroom, and utility room extract systems, as well as whole-house ventilation installations. The full range includes bends, elbows, adapters, and wall outlets to complete any standard ducting installation.
