PGG 8/3

Powerful synchronous generator PGG 8/3 with 7 kW. For the independent power supply with AC and three-phase current on construction sites, in agriculture or in the municipal environment.

Whether for commercial or municipal applications: a power source is often not guaranteed on site. This problem is quickly solved with our powerful, petrol-operated synchronous generator PGG 8/3. Thanks to puncture-proof wheels and a foldable push handle, it is easy to transport and manoeuvre on the spot. The 25 litre tank ensures long applications of up to 7 hours (at full power up to 5.5 hours), the reliable 4-stroke petrol engine (EU STAGE V) ensures a constant power rating of 7 kW. With 2 earthed sockets (AC) and a red 400 V socket (three-phase current), it offers ample connection options for your equipment. The automatic voltage regulator (AVR) also makes possible the operation of sensitive electronic devices. Useful equipment details, such as overload and oil shortage protection, as well as a robust tubular steel frame, reliably protect users and the machine against any risks or damage.
