Why this ducting earns its place
The 400 mm saddle right-flank fitting is designed for large-capacity extraction systems serving busy commercial kitchens, central food production areas, and facilities with multiple cooking stations operating simultaneously. At this bore size, you're handling substantial airflow volumes, making proper ducting design critical—the right-flank geometry allows you to change direction by 90 degrees without sharp bends that would reduce extraction velocity and spike static pressure.
Weighing just 1 kg, this component is easily handled during installation or system modification, yet it's engineered to sit confidently within large-bore ductwork carrying significant volumes of kitchen exhaust. Whether you're a fit-out contractor specifying a new high-capacity kitchen or a facilities team extending existing extraction systems, the 400 mm bore sits at the upper end of standard commercial hood sizing—suitable for open kitchens, multiple appliance installations, or establishments with demanding ventilation loads.
Correct fitting selection in large-bore systems is especially important because turbulence and pressure loss multiply as duct sizing increases. A properly specified saddle junction keeps airflow smooth and balanced, protecting fan motor efficiency and ensuring your system delivers rated extraction capacity. Combisteel's matched component range means you can build predictable, high-performance ventilation networks without guessing at compatibility or performance.
