The SMC VCHN series silencer is rated for high pressure of up to 5.0MPa. A double-layer filtration structure results in less clogging of the silencer's element, and by simply removing a bolt, the sound absorbing material can be replaced without removing the silencer. It has a built-in safety valve, which will activate when the silencer's internal pressure exceeds 1.8MPa. 35 dB(A) to noise reduction
