MWSC silencer with external thread used in compressed air systems to reduce noise levels. The noise reduction achievable through the installation of the silencer, measured at a supply pressure of 5 bar, at a distance of 1m and at an angle of 45° from the axis of the silencer, averages 35 dB depending on the size. Material: nickel-plated brass, nickel-plated sintered bronze. Operating temperature: from -10°C to +80°C. Working pressure: up to 12 bar.
