The latest generation of the QAS 5 range from Atlas Copco gives you reduced noise with levels being on average 5-8dBA, more efficiency, lower emissions and therefore a lower total cost of ownership. The QAS 5 range is also approx. 20% smaller than similar generators on the market making it much easier to transport. Each model within the range is built with a Variable Speed Drive cooling fan which adjusts to the need of the engine. This range is perfect for construction sites, events and industrial operations requiring a quieter way to generate power.
