Cummins Onan Generators

Cummins Onan commercial generators provide power to many critical applications such as for hospitals, data centers and other organizations requiring continuous uptime. The manufacturer’s extended product line ensures that specific needs are met in the most cost effective manner.

The Quiet Diesel Series models such as the one depicted above are the heavy-duty choice when low noise and low vibration are required. Their revolutionary design makes these generator sets up to 15 dB(A) quieter than other diesel-powered generators, and quieter than most gasoline sets. The units are totally enclosed, including cooling, muffler and intake systems.
