It fits standard 150 mm (15 cm) ducting and can be installed in any orientation for either extraction or intake. The terminal box is IP44 rated and the motor includes thermal overload protection. The fan can be run directly from mains or via a compatible speed controller to regulate noise and airflow. Maximum free‑airflow for the 150 mm L1 model is specified at 737 m³/h.
