This invention discloses a silent device of submerge motor for aquarium, comprising a main body, a plurality of partition boards arranged in the interlaced longitudinal and transversal directions, an open passage individually disposed at the upper and lower sections of the longitudinal and transversal partition, an air inlet and an air outlet disposed at the bottom and the top of the main body respectively, a filter cotton and a netted cover disposed at the top the main body, such that the air outlet is connected to the air inlet duct of a submerge motor. After the air enters the main body through the air inlet, the air form upper and lower turnabout passages by the interlaced partition boards to lengthen the conveyance path and diminish the molecular collision in order to achieve the silent effect.
