Cummins Commercial Quiet Diesel™ and Standard Diesel™ Series

The Quiet Diesel (QD) Series models 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. For less noise-critical applications, choose from the Cummins Onan Standard Diesel (SD) series.


  • Lower noise, vibration, harshness (NVH)
  • Self-diagnostic capability simplifies troubleshooting
