Exhaust Silencer / Muffler · Exhaust Silencer
Mann+Hummel Marine MHM-SIL-1000-30dB is a marine exhaust silencer or muffler in the Exhaust Silencer / Exhaust Silencer / Muffler category. Equipment of this class is typically installed in the exhaust-gas line between an engine or combustion unit and the uptake or outlet. Its shipboard purpose is to attenuate exhaust noise while allowing combustion gases to pass with acceptable flow resistance. The exact piping, electrical, control, foundation, and accessory arrangement depends on the vessel and the installed configuration. Any differences from adjacent models in the same family, including rating, size, material, control, certification, or accessory differences not explicitly listed here, should be confirmed in the manufacturer documentation.
