Year of construction: 2022, condition: new, machine/vehicle number: AN2301155, Atlas Copco P3500i power generator The Atlas Copco P3500i iP mobile power generator is a lightweight, efficient and reliable source of mobile power. Thanks to its high fuel efficiency and compact dimensions, the power generator is versatile for daily use, for frequent single jobs, typically for power tools as an inverter power generator or as an emergency generator. With good sound insulation, the emergency generator is very quiet and hardly louder than an electric razor. The emergency generator is equipped with a large fuel tank and therefore runs up to six hours before it needs to be refueled. Despite the large fuel tank, the emergency generator is compact and light enough to be transported across construction sites or stowed away to save space. The intelligent, variable speed control, together with the option of parallel operation, results in an efficient power supply with minimal fuel consumption, as the engine speed is adapted to the current load conditions. Key product features: Atlas Copco P 3500 i inverter power generator Pull starter Large fuel tank Engine oil level monitor Overheating protection Silenced hood, CE compliant noise level, quiet Power sockets Electric key start (12V) Inverter technology, stable voltage and frequency Instrumentation, voltmeter, hour meter Circuit breaker Wheels Engine alarm: low oil level, overload Intelligent speed control for fuel efficiency Connections for parallel operation (parallel operation kit with cables optionally available) Voltage 230V / 50Hz Peak power 3.3 Rated power 3.0 Tank capacity (l) 10.0 Starter type electric / cable Weight 45.0 Fuel Gasoline Max.
