The Helios VK 250 is a flat-style overpressure shutter engineered for 250mm diameter air outlets. Designed to automatically open when the fan starts and close when it stops, this shutter effectively prevents backdrafts and environmental ingress such as dust or insects.
It supports a maximum airflow velocity of 8 m/s, making it suitable for a wide range of ventilation systems. The number of louvres is tailored to the size of the unit for optimal performance and quiet operation. Ideal for exterior mounting, the VK 250 provides a low-profile and efficient solution for managing air discharge.
