Fan’s inlet and outlet will have a lot of noise due to high velocity of air or flow medium and due to the blade cutting the flow. PRAcoustics Fan or blower silencer will effectively reduce this noise. Fan silencer or blower silencer shall be supplied in either circular or rectangular design. The silencer shall be of absorptive type installed either at suction side or discharge side of the fan. A series of acoustic splitters arranged parallel inside the silencer casing will ensure minimum pressure drop while cutting the noise down. The aerodynamic design of the splitters will offer minimum resistance to the flow medium.
