The Helios VK 710 is a compact overpressure shutter designed to control airflow in ventilation systems. With a flat, space-saving design, it features automatic opening and closing of louvres that activate in response to the fan’s operation — opening when the fan is switched on and closing when it turns off. This automation ensures efficient airflow management and prevents unwanted air backflow.
Engineered for use in systems with airflow velocities of up to 8 m/s, the VK 710 is suitable for a range of applications. The number of louvres varies by size, ensuring optimal performance based on fan capacity. Ideal as a supplementary component to Helios fans, this shutter enhances system efficiency while maintaining a low-profile installation.
