Dirty Air Silencers
Silencers typically contain some type of absorption media. To allow the sound to reach the media, most silencers are constructed with internal walls or panels of perforated plate - however, the holes in these plates could also allow dust and dirt to reach the media. Depending upon the amount of material in the airstream, this can clog the media and gradually reduce the effectiveness of the silencer.
BAM dirty air silencers solve just this type of problem. We added a layer of heavy gauge Mylar film that keeps out the dust while allowing the silencer to still do its job.
