Sound Attenuators: ALPHAfon- SA

Sound attenuators ALPHAfon-SA are used in applications in air ducts installations that require noise reduction and low pressure drop. Typical applications are air conditioning ductworks, cooling towers, ventilation systems. ALPHAfon-SA reduces noise in workplaces (offices, industries) households, other buildings (hotels, hospitals, theaters etc) and also reduces noise emitted to the environment.

The outer surface of the sound absorptive materials is protected depending on the use and the air velocity fiberglass or perforated metal sheet.

Designing and manufacturing of sound attenuators ALPHAfon-SA is carried out utilizing our experience in manufacturing of sound attenuators since 1979. By using advanced acoustic software, we can calculate the required characteristics of the sound attenuators in order to achieve specific results. Additionally, regenerated noise from the air velocity inside the duct can also be calculated.

Types of Attenuators:

  • Parallel (P)
  • Special advanced cleaning requirements (M)
  • Cylindrical (C)
  • Stainless steel (I)
  • Angular (B)
  • Aerodynamic design (A)

Typical code example

ALPHAfon-SA/(P + M)/75/ 1200-600-850
(Distance between Baffles/Length- width- Height in mm)

For the appropriate sound attenuator ALPHAfon-SA seletion the insertion loss in dB, the volume flow rate (m3/h) and the maximum permissible total pressure drop need to be determined.

Some applications of the Sound attenuators ALPHAfon-SA are shown below:

  • Sound Attenuator
  • Sound attenuator for outlet
  • Sound attenuator for MEP soundproofing

  • Metal Noise Barriers
  • Domestic sound attenuator
  • Sound attenuators
  • Sound Attenuators application
