The Helios Fans RSD 355/800 is a high-performance duct silencer designed to minimize noise levels in ventilation and ducted air systems. Its robust housing is made from galvanized sheet steel, providing long-lasting protection and structural integrity. Internally, the silencer features premium mineral wool insulation for superior acoustic absorption, with a fleece lining on the flow side to prevent material erosion.
Engineered to match standard fan diameters (R 20), it includes a pre-configured hole pattern in compliance with DIN 24155 for easy integration. The RSD 355/800 delivers excellent sound dampening while maintaining very low airflow resistance, making it an ideal solution for commercial and industrial ventilation setups.
