Compressed air mufflers, pneumatic silencers.
Noise reduction even at high temperatures.
Porous aluminum is a high porosity noise insulation material / metal. Silencers made of porous aluminum serve for noise reduction / absorbtion for instance in pneumatic systems. When escaping from the pneumatic device into the atmosphere, compressed air causes noise levels that are unpleasant and unhealthy. This problem is solved if the air leaves the pneumatic device via a silencer/muffler.
|Technical data and additional information|
|Noise reduction||of 20-25 dB(A) and more depending on the design|
|Operating temperature||from -60°C to +400°C|
|Operating pressure|| up to 25 bar
resistant against deformations
|Volume porosity|| up to 60%
high permeability and dirt-holding capacity
|Fastening element|| made of full-aluminium, cast in one peace together with the silencer
extremely firm thanks to cast structure
no housing is required
for direct mounting on a pneumatic component
|Cleaning, maintenance||simple cleaning by backwash, mechanical and chemical cleaning|
|Functioning principle|| The acoustic energy is reduced if the exhaust air flows through
the porous structure of the silencer.
|Application|| where exhaust air is blown out of the pneumatic systems
