Silencers are indispensable elements for eliminating or reducing the characteristic noise of compressed air during discharge into the atmosphere. They should always be placed on the outlets of 3/2-, 5/2- or 5/3-way valves. When carrying out maintenance, silencers should be degreased using white spirit or paraffin and compressed air blown through them in the opposite direction to the direction of operation.
Flow rate: is measured at an inlet pressure of 6 bar with exhaust in the atmosphere. Noise level: is measured through a test using a phonometer. Placing the phonometer one meter away from the application and at the same height for ten seconds, gives an average reading of the noise generated.
