Pneumatic silencers are screwed into the exhaust bores of pneumatic valves. Normally the exhaust silencers are made of sintered bronze, stainless steel (sintered or wire mesh) or sintered plastic (VYON). For the exhaust from vacuum generators we recommend silencers with granulate filling or free-flow silencers that cannot pollute. For use with quick venting valves we offer special high-performance silencers, which can push through very high flow quantities and also withstand strong pressure thrusts.Tip: For short line paths, instead of using a one-way flow control valve on the cylinder, a more economical flow control silencer can also be used on the valve.
