RECTANGULAR PACKLESS SILENCERS
WHAT are RECTANGULAR PACKLESS SILENCERS?
IAC Packless Silencers are reactive attenuators with no acoustic infill or lining materials.
Traditional plastic film lined silencers can be replaced by packless attenuators under supply and extract conditions.
For example, under extract conditions, plastic films can be subject to chemical attack causing infill contamination and hence risk to the HVAC system.
Under supply conditions, packless silencers alleviate any risk of fiber migration downstream to sensitive areas.
Therefore, packless attenuators can be used where there is to be no risk of fiber migration or contamination.
Which are all compatible with plastic ductwork.
