High flow silencers

OI Technologies silencers help manage air exhaust, which is a major source of noise, at the output of your equipment.

They have a significant noise reduction capacity for exhaust sounds, allowing you to greatly improve working conditions, safety, protection, and employee well-being.

OI Technologies silencers will meet all your noise reduction needs.

Inside the silencer, the airflow is divided as it passes through the grille at the entrance. This creates multidirectional air jets that help reduce noise. The air is then dissipated and gently slowed through the filter. All these effects combined result in significant noise level attenuation.
