Good quality Weichai Marine Generator for sales
Good quality Weichai Marine Generator for sales
We visited OUMA factory, tested OUMA generators, we are so impressed by their low noise and small size! The design is so special and reasonable!

—— Robbie from Colombia

I have tried with many Chinese factories, OUMA is the one I feel most satisfactory. I would be the last and only one for power generators.

—— Gary from Iraq

I bought one OM20CYD for my personal use in the warehouse, excellent! It is small and quiet, you even can't feel a generator is running! Unbelievable!

—— Alexander from South Africa

We are manufacturing big power generators. OUMA units are good additions to our lines. They bring us good customers and market. I love OUMA.

Detailed Product Description


OUMA Kubota RV generators ranging from 8kw to 25kw are powered by Kubota Japan origin and equipped with Stamford alternator. As one of the most important partner of Kubota in China, OUMA generators are outstanding by smallest size and lowest noise level 57dbA. 

With in-built or external muffler and radiator, installation is more felexible. You can install the generator in a very small space, while muffler and radiator in any possible location of the vehicle. Cool and safe!

 OUMA RV generators have features to best suitable for the local application conditions:

  • 6-25kW powered by Kubota engine Japan origin.
  • Remote control with cable in driving cab.
  • Sinewave output with distortion ≤5%; Brushless self-excited alternator with auto voltage regulation, H insulation grate, 125℃ temperature rise, less ±1% steady-state voltage fluctuation, TIF<50%, THF<2%, IP22.
  • Complete display of main parameters and protections on the control panel.
  • Unique noise reduction technology, noise of silent gensets is within 62 dbA.
  • Two big service doors with easy removal from the genset body,which can be installed in small space with easy accessibility for check and maintenance.
  • Auto type door rubber seal strip and high quality noise attenuation sponge and flame-retardant sponge are applied.
  • 60℃ radiator is used on all gensets so they can be used in all weather conditions
  • 2.0mm cold-rolled steel for the genset canopy, rigid and corrosion resistant. Painting is by electrostatic spraying, no color difference or fading within 5 years.
  • Relay, fuse and AVR are in one box for easy maintenance or repair.
  • Smallest size compared with counterparts using the same engine and alternator for the same rating gensets. Save transportation cost and installation space.
  • Availability of manufacturer genuine spare parts for whole life of the gensets.
  • Assembling bolts are hidden covered by corrosion-resistant rubber cover.
