Cummins Onan now in full production of new Commercial Mobile generators certified to EPA Tier 3

Cummins Onan has launched full production of all Commercial Mobile generators in the HGJAD and HGJAE family that are certified to EPA Tier 3 regulations for small spark-ignited engines. The new Tier 3 regulations mandate lower emission levels for “Class 2″ engines.

The design changes are all internal. There is minimal impact on performance and no change at all to the fit, form and function. The most visible change is the color of the enclosures, which has changed from green to white. Purchasers of these generators should also review the mandated installation requirements.

Specification sheets for these new models are available through
