What is the design principal behind the Glaunach diffuser silencer ?
The diffuser silencer allows for staged expansion of the gas across several diffusers. Valve noise is the result of differential pressures across the valve. By spreading the pressure drop across several steps in the silencer diffuser the amplitude of each drop is lower. In addition reducing the turbulence on the down stream prevents noise from being generated. The resulting noise reduction can be as high as 50 dBA. Reducing noise at the diffuser can often reduce the need for an additional absorber section resulting in a much shorter lighter silencer.
