The Helios Fans RSD 280/400 is a compact and efficient duct silencer designed to reduce noise levels in ventilation systems while maintaining optimal airflow. Its robust housing is made from galvanized sheet steel and internally lined with high-quality mineral wool, providing effective acoustic insulation. The airflow-facing side is protected with a fleece layer to prevent material erosion and maintain long-term durability.
The silencer is engineered to fit seamlessly into standard ducting, with dimensions and mounting holes tailored to fan diameter R 20 and compliant with DIN 24155 specifications. Thanks to its low flow resistance, the RSD 280/400 is ideal for use in HVAC systems where quiet operation and efficient air delivery are essential.
