To achieve optimam output and minimum sound level from the DG set, suitable opening with acoustic hoods are provide for increasing the inflow of air required for combustion & forced ventilation. Air intake and Exhaust fans or single unit velocity Axial flow fans as per the recommendations and engine requirement are provided.
Specially designed low noise silencer is provided. Silencer & engine exhaust outlet, Connected with flexible SS below.
