QES 250 Generator

The first Volvo engine model of the QES range, the QES 250 generator is efficient and reliable with the highest power output of the diesel generators we offer for hire.

The QES range of mobile generators are specifically designed for the construction industry, with a wealth of common features geared towards ease of use. A heavy-duty lifting frame is incorporated into the design of all models, making transport and installation simple. With quick and easy cable connection and full power available in seconds, work can begin almost immediately.

Superior accessibility makes maintenance simple and all units function equally well at high or low ambient temperatures. A galvanised steel canopy and weatherproof paint coating ensures corrosion resistance. In addition, the inbuilt noise reduction and superior air filter minimise environmental impact.
