The L Series Silencer is for steam generator outlets, safety valves, start valves and air compressor breathers (blow-off valves).

The noise propagating along the pipe is channelled into the silencer. After having crossed the reactive section the gas flow enters the dissipative section, which uses a special sound-absorbing elements to deaden the medium-high frequencies.
