The Atlas Copco QAS 25’s versatility can be seen but not heard. The enclosure is sound attenuated and has a vertical radiator and exhaust discharge to ensure low dBA levels. Equipped with an Isuzu 4LE engine and a Diesel Oxidation Catalyst (DOC) to achieve Tier 4 Final emission levels, the unit comes standard with two-wire remote start capability and features a 72-gallon fuel tank for a 45-hour run time. Its voltage selector switch allows operators to adjust the machine’s output to 480 and 208/240 volt three-phase settings as well as 120/240 volt single phase for varying applications and equipment. For additional safety, the locking front panel voltage adjust potentiometer prevents unintentional adjustments to the voltage, which can cause overheating or equipment damage.
