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

Pipe-selencer with in-situ cleaning

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 small air volumes
