Rectangular Duct Silencers



Emtec RAAC Duct Silencers consist of an absorptive baffle attenuator which converts duct-borne noise energy into thermal energy within the acoustic media contained in the baffle elements


The main applications of Emtec RAAC silencers are,

  • Reduction of Mechanical noise generated by the primary air circulation fan
  • Elimination of secondary regenerated noise from terminal units, mixing chambers or pressure reducing devices


The Emtec RAAC Rectangular Duct Silencer range has been specifically designed for use in ducted ventilation and air conditioning systems.
