The Helios Fans RVK 400 is a robust ventilation shutter designed to close off air intake and extract openings efficiently. Its tight-sealing, spring-loaded mechanism ensures reliable closure, making it ideal for systems with reversible fans. The housing and louvres are constructed from tough, break-resistant plastic in a light grey finish, while the integrated stainless steel spring provides long-lasting, corrosion-resistant performance. Depending on the size, the shutter is equipped with a varying number of louvres to optimize airflow control. The RVK 400 is suitable for airflow velocities up to 6 m/s for supply air and 8 m/s for extract air, making it a dependable choice for both residential and commercial ventilation systems.
