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
