A noise reduction unit for inserting in a vacuum suction drain is adapted to be flown through by a material to be conveyed through the vacuum suction drain and comprises an inlet section with a first diameter, a middle section with a second diameter and an outlet section with a third diameter. The middle section is adapted to affect a flow velocity reduction of the material to be conveyed such that the noise level arising during the conveying process is being reduced.
