Prices & Options
The Helios Fans RSD 400/400 is a high-performance duct silencer designed to reduce noise in ventilation systems with minimal airflow impact. Constructed with a galvanized sheet steel housing, the unit is lined internally with premium mineral wool for effective acoustic insulation. A protective fleece layer on the flow side prevents material abrasion, ensuring long-term durability.
This silencer is dimensioned to match standard fan diameters (R 20) and includes a mounting hole pattern that conforms to DIN 24155, allowing easy and accurate installation. The RSD 400/400 combines robust construction with very low flow resistance, making it a reliable choice for noise control in both commercial and industrial ventilation applications.
