Weather Hood
for horizontal blow-off
purpose
rain cap - protection against ingress of precipitation (rainfall & snow)
applicable to
vent silencers
design details
​hood typically manufactured from same grade material as the silencer shell (carbon steel or stainless steel); the inner surface of the weather hood is equipped with a noise absorbing layer to minimise noise emission
Weather Hood
for vertical blow-off
purpose
rain cab - protection against ingress of precipitation (rainfall & snow) and air-borne particulate matter (sand & dust)
applicable to
vent silencers
design details
hood with integrated dust trap, typically manufactured from same grade materials as the silencer shell (carbon steel or stainless steel)
The hood comes equipped with a separate dewatering pipe for rinsing the dust trap, and is easily removable for maintenance.
Vent
for weather hoods
purpose
enables the safe venting of gases lighter than air, effectively preventing their accumulation inside the silencer.
​
applicable to
typically applied in micro silencers for hydrogen and natural gas systems.
design details
vent opening that allows gas to escape while preventing water from entering
Lambda Vent
for extreme weather conditions
purpose
prevents the ingress of rain, snow, and dust into the blow-off line and silencer even under extreme weather conditions
or maritime operations
​
applicable to
inline silencers
design details
customised for the specific gas flow in stainless steel, carbon steel, or galvanized steel.
Bird Screen
purpose
preventing birds and other animals from nesting inside the silencer
bird screens can also be used for operator protection and to prevent tools, etc. from dropping into the silencer
applicable to
vent silencers
design details
strong stainless steel grating covering the silencer outlets
Cover
for temporary use
purpose
temporary protection against any ingress of precipitation (rainfall & snow) and air-borne particulate matter (sand & dust)
applicable to
mobile vent silencers - cold gas
design details
custom-made tarpaulin on a galvanized grating – also available in antistatic material.
