The Atlas Copco QAS 40 ST3 is a diesel generator designed for construction and transport applications. Atlas Copco is a leading manufacturer of power and compressed-air equipment serving industrial, construction, and infrastructure sectors worldwide. This unit delivers reliable electrical power in environments where grid connection is unavailable or impractical.
The generator is rated for prime power output of 40 kVA (32 kW) at 50 Hz, 400 V, with a power factor of 0.8, and can deliver standby power of 44 kVA (35 kW). It draws a rated current of 57.8 amperes under prime load and achieves single-step load capability (G2 per ISO 8528/5) of 85 per cent, meaning it can accept a sudden load jump to 85 per cent of full rated power without shutdown. The alternator is a Leroy Somer LSA 42.3 S5 unit with an IP 23 degree of protection and H insulation class, rated at 45 kVA at 27 °C.
Power is generated by a four-cylinder Kubota diesel engine running at 1500 rpm. The engine is turbocharged, displaces 3.8 litres, and delivers 38 kW net power with fan load. Speed control is electronic. The fuel tank has a standard capacity of 92 litres, with an optional 282-litre capacity available. At 100 per cent rated load, fuel consumption is 9.5 litres per hour, providing an operational range of 9.7 hours on the standard tank or 27 hours with the optional extended tank.
The unit measures 2.45 metres long, 1.1 metres wide, and 1.48 metres high, with an empty weight of 1039 kilograms. The engine has accumulated 6640 operating hours. Noise output is rated at a sound power level of 89–91 dB(A) and a sound pressure level of 60–63 dB(A) at 7 metres distance. This machine carries CE marking (Declaration of Conformity) and is offered with a valid inspection certificate and manufacturer warranty. The unit was built in 2023 and is located in the Netherlands.
