The Helios Fans RSD 400/1200 is a premium duct silencer engineered for effective noise reduction in ventilation systems. It features a sturdy housing made of galvanized sheet steel and is internally lined with high-quality mineral wool to absorb sound. To prevent fiber erosion, the flow side is protected by a durable fleece covering.
This model is specifically designed to align with standard fan diameters (R 20) and includes a mounting hole pattern conforming to DIN 24155 for straightforward installation. With exceptionally low flow resistance, the RSD 400/1200 provides reliable acoustic performance without compromising system efficiency, making it ideal for both commercial and industrial HVAC applications.
