Sonodec 25 TRD
The Sonodec 25 TRD consists of a perforated aluminum/polyester laminate inner duct, thermally and acoustically insulated with a glass wool layer and provided with an aluminum/polyester laminate outer jacket. A plastic barrier between the inner duct and the glass wool prevents particle migration into the air stream. Both ends are taped to create ready-made connections.
The Sonodec 25 TRD has an increased insertion loss while the Sonodec 25 GLX has an increased sound attenuation.
application
- air supply systems
- air conditioning systems
- sound attenuator
- the reduction of noise from machines
