The Helios Fans RSD 560/1200 is a high-performance duct silencer engineered for effective noise reduction in ventilation systems. Its housing is constructed from galvanized sheet steel for superior durability and corrosion resistance. Internally, the silencer is lined with high-quality mineral wool to absorb sound effectively, while a fleece layer on the flow side prevents fiber erosion and ensures long-term reliability.
Designed to fit standard fan diameters (R 20), the RSD 560/1200 includes a mounting hole pattern in accordance with DIN 24155, allowing for straightforward and secure installation. Its aerodynamic construction delivers excellent sound attenuation with minimal impact on airflow, making it ideal for use in commercial HVAC systems where acoustic performance and efficiency are essential.
