Suction and discharge silencers SR

SR silencers are designed to effectively reduce suction and discharge noise from Roots blowers, vacuum pumps and liquid ring or rotary vane compressors.

The installation of an SR type silencer requires a pressure inside the silencer of less than 0.5 Barg. If the pressure is greater than 0.5 Barg the silencer will be subject to PED 97/23 EC, the risk category to which the equipment is subject must be determined.

Our silencers are based on two attenuation principles :

Absorption devices (SR15 and SR25)

Reactive device and wave phase shifter coupled with an absorption device (SR30 and SR40)
