SilentFlow is an adaptive circular sound attenuator designed for rectangular or circular HVAC ducts with diameters ranging from 80 to 315 mm. It absorbs noise generated by ventilation equipment (pumps, compressors, air handling units, terminal units, etc.) that propagates through intake and supply networks or radiates from acoustic casings. It incorporates technology that boosts low-frequency performance while maintaining a short unit length. Featuring a seal at each end to ensure a perfect airtight fit, it consists of an inner perforated galvanized steel shell, acoustic insulation, a row of electronic components, and an outer galvanized steel shell. Power supply unit included (max. power consumption: 3W).
