The Helios VK 630 overpressure shutter features a flat design that automatically opens when the connected fan is running and closes when the fan is switched off. It is designed to handle airflow velocities up to a maximum of 8 m/s.
The number of louvres adjusts according to the shutter size, optimizing airflow while providing effective protection against backdrafts. This makes it a dependable component for ventilation systems requiring automatic air control and efficient sealing.
