SMC® VCHN4-12 High Pressure Silencer, 1-1/4 in Male Port, 5 MPa Pressure, 5 to 80 deg C, 240 mm OAL

SMC® VCHN silencer is rated for high pressure of up to 5 MPa. 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. The VCHN has a built-in safety valve, which will activate when the silencer's internal pressure exceeds 1.8 MPa. At a supply pressure of 4 MPa, back pressure 2 MPa, the VCHN provides a 35 dB(A) noise level reduction. A-freeze reduction option is available.
