The Helios VK 70/40 overpressure shutter features a flat design that automatically opens when the fan is operating and closes when the fan is turned off. It is suitable for use with airflow velocities up to a maximum of 8 m/s. The number of louvres varies according to the shutter size, allowing optimized airflow and reliable protection against backdrafts in ventilation systems.
