Silencer integrated in the chimney

ALFA-principle (Alternative fibre-free absorber)

Advantages regarding the standard silencers:

  • Space savings
  • Lower pressure drop - Energy savings
  • Easy to clean
  • Highly effective at low frequencies
  • Short assembly time

Use:

  • When there is a danger for normal silencers to be polluted (raisins, soot, lac, … in the gasstream)
  • When a high efficiency in low frequencies is needed
  • When no supplementary pressure drop is allowed in the system
  • For space savings
  • With high air volumes
