Absorbs the noise from ventilation equipment (pumps, compressors, HVAC, terminal equipment…) that propagates in the extraction and blowing networks or outside the acoustic boxes. Equipped with a joint at each end for a watertight connection, it is composed of an inner shell made of perforated galvanized steel sheet, a sound absorber, an outer shell made of galvanized steel sheet.

SilentFlow™ is an active noise reduction solution designed to ensure acoustic comfort without obstructing airflow.
Developed by our team, this compact and modular device relies on patented acoustic intelligence technology that adapts in real time to the surrounding noise environment.
Using a network of microphones and AI-controlled membranes, SilentFlow™ precisely targets low-frequency noise – often the hardest to eliminate – achieving reductions of up to −40 dB. Its discreet design, proven performance, and seamless integration with ventilation or suction systems make it the ideal solution for industrial, office, or noise-sensitive environments.
