The Helios Fans RSD 500/600 is a high-performance inline duct silencer designed to minimize noise in ventilation systems without compromising airflow. Its rugged housing is constructed from galvanized sheet steel, providing long-term durability and protection against corrosion. Inside, the unit is lined with premium-grade mineral wool for effective sound absorption, while the flow-side is finished with a protective fleece to prevent material wear and maintain airflow efficiency.
This model is engineered to match standard fan diameters (R 20) and includes a mounting hole pattern compliant with DIN 24155 for easy integration. Offering very low flow resistance, the RSD 500/600 is ideal for use in commercial and industrial air systems requiring reliable noise attenuation.
