The Helios Fans RSD 450/1200 is a high-performance duct silencer designed to provide superior noise attenuation in ventilation and duct systems. The housing is constructed from robust galvanized sheet steel, ensuring long-term durability and corrosion resistance. Internally, the unit is lined with high-quality mineral wool for efficient sound absorption, and a protective fleece layer on the flow side prevents fiber abrasion and ensures long-lasting performance.
Engineered for easy integration, this silencer matches standard fan diameters (R 20) and follows the DIN 24155 hole pattern specification. Its low flow resistance design ensures optimal airflow efficiency, making the RSD 450/1200 ideal for commercial and industrial HVAC systems requiring reliable and quiet air movement.
