The Elta 064‑0710‑C is a 710mm louvre shutter designed to facilitate passive airflow control in ventilation systems. Constructed from tough light grey polypropylene, it provides excellent durability and resistance to environmental exposure. The shutter operates automatically, opening when airflow is present, with no need for manual adjustment. It is intended for standalone installation, ideally downstream from the fan, making it an effective solution for managing air movement in ducted applications.
