Helios Fans VK 355

The Helios VK 355 is a flat-design overpressure shutter designed for 355mm air outlets, offering automatic opening and closing in sync with the operation of the connected fan. This mechanism prevents backdrafts and protects against dust and outdoor air entering the system when the fan is off.

Capable of handling airflow speeds up to 8 m/​s, the VK 355 ensures smooth ventilation performance in both residential and commercial installations. The number of louvres is optimized according to the shutter size to maintain airflow efficiency while reducing operational noise. It serves as a reliable and maintenance-free solution for enhancing ventilation system control and energy efficiency.
