Despite its sizeable power, the EF3000iSE is whisper-quiet, producing noise levels ranging from 54 to a maximum of 61 dB - and because it's mounted on four wheels, moving it around couldn't be easier. The Smart Throttle / Economy Control feature automatically adjusts engine speed to match the load, for greater fuel efficiency and reduced engine wear.
