C2..QS - Q-Seal Circular 2D Open Type
otc
Features
The 'C2..QS' (Q-Seal) circular attenuators are nominally two diameters long. They have an impervious seal between the acoustic fill and ambient air. They are used in critical applications where the possibility of fibre contamination of the acoustic fill is not allowed. There is a penalty on the acoustic performance in exchange for the certainty that fibre fly is eliminated. Typical applications are as follows: -
  • clean rooms
  • operating theatres
  • wet environments where attenuators are exposed to the elements
  • kitchen exhaust systems
  • applications where workers are sensitive to fibre exposure
