RRE or RRS silencers are multi-chamber reactive units for applications where better than standard acoustic performance is requried.
These residential grade silencers have good pressure drop characteristics and are available with side or end entry or side inlet and outlet.
They can be installed in any orientation without loss of acoustic performance.

These silencers can be used for noise control of two or four stroke diesel engines, the intake and discharge of rotary and reciprocating blowers, the intake and discharge of vacuum pumps and air compressors and for noise control of all gas handling systems. Designed for maximum all round performance, these silencers can provide overall reductions of 25-30 dB(A) depending on the acoustic characteristics of the machine to be silenced.

NAP RRE silencers are dual chamber reactive acoustic filters with good low frequency performance. The RRE silencer, whether supplied with side or end entry, has a low pressure drop and can be used in most situations to provide reductions of approximately 25-30 dB(A) across the entire frequency range.
