The Helios Fans RSD 315/1200 is a robust duct silencer engineered to reduce noise in ventilation systems while preserving airflow efficiency. Constructed from galvanized sheet steel, it features a high-quality mineral wool lining for effective acoustic insulation. A durable fleece on the flow-facing side protects the insulation from wear and erosion.
This silencer is designed with dimensions and mounting patterns tailored to standard fan diameters (R 20), following the specifications of DIN 24155. Its low-flow resistance makes it ideal for commercial or industrial applications where quiet operation is essential. The RSD 315/1200 offers reliable and long-lasting performance in demanding ventilation environments.
