– The ETS NORD NRF 100-600-50 round silencer is designed for 100 mm ventilation ducts, offering exceptional noise reduction with minimal impact on airflow.
– Featuring 50 mm mineral wool sound absorption, a perforated inner tube, and galvanised steel outer shell, it ensures durability and high performance. A fabric lining between the tube and insulation prevents particle migration into the duct system.
– This 100 mm duct silencer meets airtightness class D and, with its factory-fitted rubber gasket, guarantees secure, leak-free connections to reduce pressure loss.
– Ideal for residential, office, and commercial HVAC systems, it effectively attenuates fan noise, regeneration sounds, and terminal unit noise.
– Compact and easy to install without sealants or adhesives, the NRF 100-600-50 mineral wool duct silencer is perfect for both new installations and retrofits.
– For enhanced performance, multiple units can be installed in series.
