GLAUNACH inline diffuser silencer

Diffuser silencer for closed systems: muffled in-line expansion of pressurised gases without releasing them to atmosphere. Up to 50 dB.

The inline silencer is a type D diffuser built into a flanged pressure-retaining body, for systems where the gas has to stay inside the piping: blow-down into a vessel, condenser injection, turbine bypass. The fluid expands through a multitude of small bores into stainless steel wire mesh, and leaves through the outlet flange at reduced pressure and noise.

Selection data we need

Medium and its state, mass flow, inlet pressure and temperature, allowable back pressure, inlet size and flange rating, required noise level and the distance at which it applies, installation (indoor, roof, height), material preference, quantity.

Applications

  • Venting or blowing down into a pipe or pressure vessel
  • Condenser injection
  • Turbine bypass
  • Closed systems that must not release to atmosphere

Models: Vent Silencers

Glaunach

GLAUNACH type A absorbing silencer

Circular baffle absorbing silencer in stainless steel with mineral wool and glass fabric lining and a radial diffuser inlet. No pressure drop, 25 dB or more depending on the number of absorber stages.

Glaunach

GLAUNACH type D diffuser silencer

Single- or multi-stage small-bore radial diffuser wrapped in finely woven stainless steel wire mesh. Up to 50 dB in a substantially smaller and lighter unit than an absorbing silencer.

Glaunach

GLAUNACH type DA diffuser silencer with insulated shell

Type D diffuser silencer with an additional glass fabric and mineral wool insulation of the inner shell for better thermal and acoustic insulation of the outer shell.
