Sonodec 25 TRD - flexible sound attenuator ⌀127mm / L=1m

The SONODEC 25 TRD consists of a perforated aluminum laminate inner duct, thermally and acoustically insulated with a glass wool layer and fitted with an aluminum laminate outer jacket. A barrier between the inner duct and the glass wool prevents migration of glass wool particles in the air flow. Both ends are taped to create ready-made connections. The connection is female and fits directly over a male end.
