Diesel Generator 20-50 kVA, Single-Phase Diesel Generator

For businesses that need to stay operational regardless of what the grid is doing, the FAW diesel generator range provides the output capacity to cover real commercial loads without interruption. Automatic changeover means the generator takes over the moment power is lost, with no manual intervention required and minimal disruption to your team or operations. With output options from 20 kVA to 50 kVA and sound-attenuated enclosures as standard, there is a configuration suited to the scale and environment of most commercial sites.

 

Fuel consumption is published at every load band rather than as a single headline number, so running cost can be calculated against how the set will actually be used. The engines are four cylinder water-cooled diesels running at 1500rpm, normally aspirated on the FAW sets, paired with a brushless alternator and AVR for stable voltage under changing load. Confirm access and foundation early.

Product Features

  • Prime And Standby Ratings Stated Separately
    Prime power output of 20kVA, with standby ratings of 22kVA. Both figures are published because they are routinely conflated, and specifying against the wrong one is the most common sizing error in this category.
  • Single Phase
    Single phase at 230V on the FAW 20 and 50kVA, all at 50Hz.
  • Automatic Changeover Included
    An automatic transfer switch is supplied as standard, along with maintenance-free batteries and a trickle charger. The set starts and takes the load without anyone present, which is the difference between a generator and a backup plan.
  • Outdoor Ready
    A silent, weather-resistant canopy with lockable doors, rated to stand outside without building a housing or an acoustic enclosure for it.
  • Published Fuel Consumption At Every Load Band
    6.3, 4.7, 3.2 and 1.6 litres per hour on the 20kVA at 100%, 75%, 50% and 25% load. Running cost can be calculated against the actual load rather than a single headline figure.
  • Long Runtime Between Refuels
    A 200 litre fuel tank on the FAW sets.
  • Proven Engine Platform
    Four cylinder water-cooled diesel engines running at 1500rpm, normally aspirated on the FAW, with replaceable fuel, oil and dry element air filters.
  • Stable Output
    A brushless alternator with AVR and Class H insulation, protected by a circuit breaker. Stable voltage under changing load is what protects the equipment connected to it.
  • Engine Protection
    A four-way protection system with high oil pressure and high temperature shutdown, which stops the engine before damage occurs rather than after.
  • Tested Before Delivery
    Every set undergoes comprehensive testing and a pre-delivery inspection before it leaves.
  • Siting And Access
    2100 × 920 × 1050mm at 782kg for the FAW sets. Worth confirming access and foundation early, since both are genuine pre-purchase considerations at this weight.

Very rarely do you find a person with such diligence, focus and attention to detail as I have from the service rendered by Mr Carlos da Silva.

The service team and support were fantastic in dealing with my machine even though it’s definitely a much older model

Great to see some places still doing honest business. I recently sourced an inverter for my small business from Oxbow and was amazed at how much care and consideration they gave to my purchase. I had a salesperson on site for assessment and within a week had my inverter installed and functioning perfectly. Very impressed with their service and urgency.

We recently upgraded to a Fujifilm C750 through Oxbow and the improvement in print quality has been noticeable immediately. Their technician handled everything from delivery to network setup and even configured scan-to-email for the whole team. What stood out was how smoothly the transition happened without any downtime.

We chose a Fujifilm device through Oxbow after comparing a few options. Their consultant gave us honest advice based on our usage rather than pushing the most expensive option. The machine has performed well so far. Appreciate the transparency.
