HEAVY DUTY LINE Generators – Uncompromising Power That Simply Pays Off

Reliable field power is not a matter of chance but the result of thoughtful engineering. Generators powered by Vanguard engines were created for users whose top priority is full operational continuity, uncompromising safety, and maximum performance on site. We have combined industrial durability with solutions that lower the Total Cost of Ownership (TCO) with every startup and every service check. And with the arrival of new models, they receive a new name – HEAVY DUTY LINE.

This product line was created to work harder, provide confidence where the power grid cannot reach, and… pay for itself faster.



First and foremost, the proven engines from Vanguard – a global leader in industrial engine manufacturing. We have been using them in our products for many years, giving us a in-depth understanding of their full potential.

The new generator models are the result of combining reliable FOGO solutions with the technology of this American brand. We focused on engineering enhancements that increase operator comfort and speed up routine inspections. As a result, we have created equipment that lowers operating costs and brings real profit to equipment owners.

Innovative Transport Guard System

Rushing on a construction site can easily lead to oversight. For example, simply forgetting to turn off the fuel valve before loading. Transporting equipment over rough roads in these conditions risks flooding the carburetor or mixing fuel with engine oil. In select HEAVY DUTY LINE models, this type of error has been eliminated. The patented Transport Guard technology integrates a single-function fuel and ignition shut-off into one solution. The equipment always arrives at the job site ready for immediate startup, with no surprises and no unnecessary downtime.



Electronic Fuel Injection (EFI)

Electronic Fuel Injection (EFI) technology guarantees trouble-free electric starting under all conditions and demonstrates higher tolerance to fuel that has been sitting in the tank for extended periods. The speed monitoring system precisely meters the right amount of fuel exactly when needed. This translates into higher power output and superior fuel efficiency, which in practice means lower costs and longer operation on a single tank.



Electronic Throttle Control (ETC)

ETC technology guarantees a stable engine speed and responds instantly to load changes during operation. Electronic Throttle Control ensures smooth operation and high user comfort. The device handles sudden power surges more efficiently, maintaining optimal performance in every situation.

Cyclone Air Filter

Operating in harsh, dust-heavy environments requires exceptional engine protection. The cyclone air filter uses centrifugal force to pre-clean incoming air from heavy debris before it reaches the main element. This ensures longer engine life, reduced load on the main filter, less frequent maintenance, as well as stable power output and operational efficiency.

Lightning-Fast Service Access

Time spent in the shop is time the generator isn't earning money. The robust frame design and high-quality components were engineered to provide direct and easy access to assemblies and service parts. Routine maintenance runs smoothly, keeping downtime to an absolute minimum.

Full 3-Year Commercial Warranty

We back the quality of the new design with a concrete commitment. The entire series is covered by a full 3-year commercial warranty for the complete generator set (provided regular maintenance is maintained). That is a full 36 months of peace of mind and efficient operation in the toughest working conditions.

Where Will HEAVY DUTY LINE Generators Perform Best?

A wide power range from a few to several dozen kilowatts allows for a precise fit to the specifics of any job. Thanks to its flexibility, this line excels in:
  • construction and heavy outdoor work, guaranteeing a trouble-free power supply for machines and tools in demanding conditions,
  • the commercial and utility sectors, providing a reliable and stable power source where dependability and business continuity matter (as a backup power source for facilities such as homes, offices, workshops, or commercial venues),
  • professional and special applications, offering an excellent combination of durability, power tailoring, and low fuel consumption.
