The Elta 064‑0450‑C is a 450mm louvre shutter engineered for effective airflow management in ventilation systems. Constructed from tough, light grey polypropylene, it ensures durability and resistance to environmental wear. The shutter activates automatically with airflow, eliminating the need for manual adjustment. Designed for independent installation, it is ideally mounted downstream of the fan, making it a practical solution for improving ventilation efficiency and passive air regulation.
