Rigid Flat Ducting - 220mm x 90mm

A range of 220 × 90 mm rigid rectangular plastic ducting components for space-restricted ventilation installations, including selected higher-airflow systems and cooker hoods with compatible connections.

The nominal cross-sectional area is 19,800 mm², approximately 12% greater than nominal 150 mm round ducting. Cross-sectional area alone does not establish equivalent airflow or pressure loss. Select ducting based on the appliance manufacturer's guidance, required airflow, available pressure, duct length and bends.
