The Helios VK 50/25 is a flat-design overpressure shutter that automatically opens when the fan operates and closes when it stops, preventing unwanted airflow reversal. Designed to handle airflow velocities up to 8 m/s, it offers effective backdraft protection for ventilation systems.
The number of louvres varies with shutter size, optimizing airflow and pressure control. This shutter is suitable for a variety of residential and commercial ventilation applications requiring dependable airflow regulation and protection.
