The present invention relates to the technological field of acoustic filters applied to hermetic compressors. Problem to be solved: In hermetic compressors applied in cooling system, the work fluid sucked by the compression mechanism is hotter than the work fluid coming from the evaporator, and it is known that greater the temperature of this fluid, smaller is the efficiency of the compressor. Resolution of the problem: It is revealed a suction acoustic filter and a suction line including this acoustic filter capable of guarantee that the compression mechanism works mainly with the work fluid coming from the evaporator, which is colder than the work fluid accumulated inside the environment defined by the hermetic housing of compressor.
