AAL-SIL-1200-35dB

Aalborg Industries Silencer AAL-SIL-1200-35dB is identified in the source list as a marine exhaust silencer. It is installed in exhaust-gas piping between an engine or generator and the funnel outlet, with supports and expansion arrangements appropriate to the exhaust system. Its purpose is to reduce exhaust-noise transmission while allowing engine exhaust gas to pass with acceptable system resistance. The source record provides no additional model-specific operating figure beyond the listed designation and category. Internal acoustic elements, casing, insulation, drainage and connection geometry are selected for the installed engine and exhaust arrangement. The exact model designation and any attenuation value in the source distinguish acoustic duty and physical size from neighboring silencers; refer to the manufacturer documentation for the exact figure.

Common failures & inspection points

●Internal baffle or acoustic-element damage caused by vibration, thermal cycling or corrosion, resulting in rattling, increased noise or rising exhaust resistance
●Casing corrosion or cracking caused by condensate, salt contamination or thermal stress, resulting in exhaust leakage or soot staining
●Insulation deterioration caused by water ingress or heat damage, resulting in hot external surfaces and damaged lagging
●Drain blockage caused by soot or corrosion products, resulting in condensate accumulation and accelerated internal corrosion
●Support or expansion-joint failure caused by vibration or pipe growth, resulting in misalignment, cracking or abnormal load on silencer connections

Service & Maintenance

Inspect casing, supports, flexible joints, insulation and drain arrangements for leakage, corrosion and heat damage. Listen for internal rattling and compare exhaust noise and backpressure indications with the vessel's established normal condition where monitored. Keep condensate drains clear and repair damaged insulation promptly. Inspect adjacent piping and supports for thermal-growth or vibration problems that can load the silencer. Do not modify internal elements without manufacturer approval because acoustic performance and backpressure are linked to design. Refer to the manufacturer documentation for the exact figure for permissible backpressure and repair criteria.

Replacement Parts

Keep gaskets, flexible-joint components where applicable, drain fittings, insulation materials and mounting hardware recommended for the installation. Large internal acoustic elements or complete silencers are normally strategic spares. Verify replacement dimensions and engine compatibility from approved exhaust-system documentation.
