The Elta 064‑0250‑C is a 250mm louvre shutter constructed from durable light grey polypropylene, offering reliable performance and corrosion resistance. Designed to open automatically when airflow is present, it enables efficient air movement without the need for manual operation. The shutter is intended to be mounted independently of the fan, ideally in a downstream position, making it suitable for a wide range of ventilation setups where passive airflow control is required.
