•Evaporative spec: For trailer applications required to meet Tier III Evaporative emissions of the California Air Resources board.
Effective January 1, 2011, gasoline generator sets on trailers, diesel chassis or any other non-motorized mobile apparatus must have an EVAP generator set, approved tank, EVAP canister, hoses and fittings all meeting the CARB Tier 3 and EPA phase 3 standards and specifications. This law applies in all 50 states.
Generator weight does not include battery charger or splined shaft.

Generator set performance
Hydraulic pump
•Fixed displacement gear pump, 1.8 Gal/min at 2500 psi
•Hydraulic pump is rated with the pump  idle
•When using a non-Cummins Onan pump supplied by the customer, the hydraulic pump shaft seals must be capable of operating in a temperature environment of 225° F to 250° F. Seal failure will result in equipment damage
