Key Features

01/

Exceptional Low-Frequency Attenuation: They are specifically designed to target low-frequency and broadband noise where traditional porous or reactive silencers often struggle.

02/

Low Flow Resistance & Pressure Loss: Because the vibrating plates are flush-mounted with the duct, there is no sudden change in duct area or obstruction in the flow path. This maintains optimal system performance and saves energy.

03/

Contaminant and Heat Resistant: Unlike traditional porous absorptive materials (like mineral wool), plate silencers feature smooth, solid surfaces. This makes them highly resistant to fouling, dirt, frost, heat, and humidity.

04/

Lower Maintenance Needs: Because they do not absorb particulate matter like traditional materials do, they require almost no internal cleaning or replacement.

Applications

Ventilation Systems

In commercial and industrial buildings, plate silencers are used to reduce the noise generated by ventilation fans and air ducts. This helps to create a more comfortable working environment and comply with noise regulations.

Exhaust Systems

In factories and power plants, plate silencers are used to reduce the noise emitted by exhaust gases. This is important for protecting the health of workers and minimizing the impact on the surrounding environment.

HVAC Systems

In heating, ventilation, and air conditioning (HVAC) systems, plate silencers are used to reduce the noise generated by the equipment and the airflow. This improves the comfort of the building occupants and reduces the noise pollution.
