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.
