Combination Absorptive/Reactive Silencers

The Critical Grade RR/AE or RR/AS combination absorptive/reactive silencers provide the very highest noise control in all critical situations.  They are a multi-chamber design with internal absorption to provide maximum broad band performance, and can be used for critical noise control of gas exhausts and air flows in all conditions.  Designed for maximum performance at low frequency, they can provide overall reductions of greater than 30dB(A) depending upon the application and pressure loss that can be tolerated.

They feature:

• Standard designs from 50NB to 500NB inlet.

• Special spark arrestor designs for where spark control is required.

• Heavy gauge mild steel construction with silicon based heat resistant aluminium paint finish for temperatures up to 600°C.

Customised designs are available for specific attenuation or size requirements.
