The silencers are indispensable

elements for eliminating or reducing

the characteristic noise of compressed

air during discharge operations. They

should always be placed on the outlets

of 3/2, 5/2 or 5/3-way valves.

When carrying out maintenance, the

silencers should be degreased using

white spirit or paraffin and compressed

air blown through them in the opposite

direction to operation.

Flow rate: determined with inlet supply 6

bar and output in atmosphere.

Noise level: determined through a test

which is carried out using a phonometer.

Placing the phonometer one meter away

from the application at the same height

for a period of ten seconds gives an

average reading of the noise generated.
