The gravity-operated louvres respond to airflow without the need for manual adjustment or power. During ventilation, the louvres open to allow efficient airflow, then close automatically when the fan is switched off to help reduce backdrafts, cold air ingress, and draughts.
Manufactured for long-term outdoor use, the PER-450 W features a durable, weather-resistant construction suitable for demanding environmental conditions. It is an ideal solution for residential, commercial, and industrial ventilation systems, combining reliable operation with simple installation and low maintenance.
