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.
