Prices & Options
The Helios VK 100 is an automatic overpressure shutter designed to seal external air outlets effectively. Featuring a conical spigot at the rear and a foam sealing strip, it ensures quick and secure plug-in installation into 100mm duct systems.
Constructed from UV-resistant and impact-resistant white plastic, the frame and louvres are built to withstand outdoor exposure while maintaining long-term performance. The number of louvres may vary based on unit size, but all are engineered to respond automatically to airflow, closing securely when the system is off to prevent backdrafts and debris entry. Ideal for residential and commercial ventilation systems.
