The Elta 019‑0560-STD flanged damper, measuring 560mm, is designed to prevent air from flowing backward when the fan is off, ensuring efficient airflow control in ventilation systems. It attaches directly to the fan case flange for easy and secure installation. Manufactured from hot dip galvanised steel, this damper offers excellent durability and resistance to corrosion. The butterfly blades, also made from galvanised steel, operate reliably to maintain correct airflow direction. This model is suitable for both horizontal and vertical (upward airflow) mounting positions, making it adaptable to a variety of ventilation setups.
