This 2.5-metre length of 150mm round PVC duct provides a rigid, corrosion-resistant air path for higher-volume residential and light-commercial ventilation systems. The lightweight PVC construction is easy to cut, handle and connect, while the smooth internal bore supports efficient airflow with low pressure loss and reduced dust accumulation. Its rigid circular profile maintains consistent duct geometry through ceiling voids, walls and service spaces. The duct integrates with the matching Airmiq 150mm joiners, dampers and transition fittings.
