Helios Fans RVK 200

The Helios Fans RVK 200 is a robust louvre cover designed to effectively seal and protect supply and extract air openings. Engineered for use with reversible fans, this cover features tight-closing, spring-loaded flaps that respond efficiently to airflow direction. Constructed from impact-resistant plastic in light grey, the unit offers lasting durability and resistance to wear. A stainless steel spring mechanism ensures reliable flap operation, maintaining an airtight seal when closed. The number of louvres is adjusted based on the size of the unit to ensure optimal air distribution. Suitable for supply air velocities up to 6 m/​s and extract air up to 8 m/​s, the RVK 200 is an ideal solution for maintaining airflow efficiency and preventing backdraft in both residential and commercial ventilation systems.
