Silencer CW-S 520 990323502

Effective sound attenuation in ventilation systems

The CW-S 520 silencer is a key component of the ComfoWell system, designed to reduce noise in ventilation installations. Its construction allows for effective attenuation of sounds of various frequencies, ensuring acoustic comfort in used rooms. Made of Sendzimir galvanized steel, it guarantees durability and corrosion resistance.

Construction and application

The silencer is designed to connect different variants of front plates and distribution boxes with distribution pipes in the ComfoWell system. Compact dimensions (500 mm length, 520 mm width and 230 mm height) facilitate installation even in limited spaces. Thanks to special clamping strips and connectors, installation is quick and convenient for both professionals and end users. It is worth remembering that the silencer is sold without connecting plates - they must be purchased separately.

Attenuation characteristics

The CW-S 520 silencer is characterized by high sound attenuation parameters at different frequencies:

• 63 Hz: 0.2 dB
• 125 Hz: 6.3 dB
• 250 Hz: 10.3 dB
• 500 Hz: 16.5 dB
• 1000 Hz: 12 dB
• 2000 Hz: 20.4 dB
• 4000 Hz: 15 dB
• 8000 Hz: 13.5 dB

These values confirm its effectiveness in reducing both low and high tones, which translates into a noticeable improvement in acoustic comfort. The maximum medium temperature at which the silencer can operate is 80°C. Galvanized steel provides resistance to weather conditions and long-term use.
