Round silencer: DN 160 990318033

Acoustic silencer for ventilation ducts – effective noise reduction

This round acoustic silencer, with a diameter of 160 mm, is a key element of ventilation systems designed to minimize the noise of flowing air. It is ideal for both commercial installations and residential buildings where acoustic comfort is a priority. The flexible design facilitates installation and adaptation to existing infrastructure.

This silencer is characterized by high damping properties at different frequencies. The use of glass wool as an insulating material with a thickness of 50 mm ensures effective sound absorption. The rigid internal lining increases the durability and stability of the structure, and also improves the acoustic parameters. This reduces the noise level generated by operating ventilation systems, providing quiet and comfortable operation of the devices.

Construction and parameters for professionals

The silencer is made of aluminum both inside and outside, which guarantees corrosion resistance and long-term operation. It has push-fit ends to facilitate quick and secure installation in ventilation ducts. The working length of the silencer is 1000 mm, which provides an adequate damping surface. The maximum medium temperature (continuous) is 200°C, which allows it to be used in a wide range of applications. Free air flow is 100%, which means there is no significant decrease in the efficiency of the ventilation system after the silencer is installed.

It is worth paying attention to the detailed damping parameters for individual frequencies: attenuation at 125 Hz is -5 dB, for 250 Hz -10 dB, for 500 Hz -21 dB, for 1000 Hz -39 dB, for 2000 Hz -30 dB, for 4000 Hz -20 dB and for 8000 Hz -18 dB. This data allows you to precisely select the silencer to the specific acoustic requirements of a given project. The lack of a vapor barrier layer and protective fabric does not negatively affect its functionality in typical ventilation applications.
