THE WORKING VIEW

Why this ducting earns its place

Duct connections seal the joints in your extraction system—a small component with a big job. At Ø400 mm, this Combisteel connector handles large kitchens running high-volume cooking with central extraction. A loose or damaged connection loses air, forces your fan to work harder, and kills extraction performance at the hood where it matters most.

Combisteel ducting is engineered to withstand temperature swings, vibration, and continuous airflow stress. Ø400 mm is sized for kitchens serving 20+ covers simultaneously or high-output cooking stations where extraction must be reliable and efficient.

BEFORE YOU BUY

Questions, answered straight

Connector size matches your ductwork inner diameter. Measure your existing duct or canopy riser outlet. Ø400 is for larger kitchens or higher airflow demands; Ø350 is adequate for medium-scale operations.

Duct diameter is part of the sizing calculation. A Ø400 mm duct with a well-designed extraction system typically needs a 2000–5000 m³/h fan depending on hood length and cooking intensity. Our team on 01792 732702 can advise on sizing.

Yes—Combisteel connectors accept both types, as long as diameters match. Secure all connections with clamps to ensure the joint is airtight.

Check monthly during your extraction service. Look for cracks, looseness, or dents. Replace immediately if damaged; loose connections force fans to work inefficiently.

Yes—a poorly sealed Ø400 mm system wastes 30–40% of fan power. Replacing damaged connections and ensuring airtight joints is one of the fastest ways to improve extraction efficiency and lower running costs.
