The Helios Fans RSD 250/900 is a high-quality duct silencer designed to suppress noise in ventilation systems while maintaining efficient airflow. Constructed with a robust galvanized sheet steel housing, it is internally lined with high-density mineral wool for excellent acoustic insulation. The airflow side features a protective fleece to guard against fiber erosion, ensuring long-term performance and durability.
Engineered to integrate seamlessly into standard duct systems, the RSD 250/900 adheres to standard fan diameters (R 20) and follows the mounting hole pattern defined by DIN 24155. With minimal pressure drop and outstanding noise attenuation, this silencer is ideal for applications requiring quiet operation and consistent airflow.
