RRAE (end entry) and RRAS (side entry) silencers provide the very highest noise control in all critical situations.
These silencers have internal erosion resistant acoustic material for high performance broad band attenuation, protected by heavy duty perforated sheet.
Multi-chamber reactive design combines with the absorption principle to provide the maximum performance at all frequencies.

These silencers can be used for critical noise control of gas exhausts and air flows in all conditions.
Contact us if you require higher performances (super critical) in single or multiple arrangements.

NAP RRAE silencers are multi-chambered reactive silencers with internal absorption to provide maximum broad band performance.
These silencers are designed for maximum performance at low frequencies and can provide overall reductions of greater than 30 dB(A) depending on the application and the pressure loss that can be tolerated.
