New QAS range of heavy duty generating sets from Atlas Copco


New re-designed QAS generating sets will be available for the entire range from QAS 14-325 comprising 12 models.

The new range of QAS generating sets from Atlas Copco feature an improved, more compact and robust design and are also available in both 50 Hz and 60 Hz options.
Comprising twelve models, including four newly introduced QAS 14-40 Kubota-  powered sets, the range also includes ratings between 60 kVA – 325 kVA.
The QAS 60, 80 and 100 are powered by Perkins diesel engines whilst the QAS 125, 150, 200, 250 and 325 are powered by Volvo engines.


The new range is housed in a significantly smaller and robust enclosure up to 40% smaller than previous QAS models.
Nevertheless it has been designed to deliver the same accurate and 100% stable prime power in temperatures of 40ºC - with some models operating at 45ºC - and an altitude of 1000 m.

Environment friendly

Atlas Copco’s QAS range of generating sets are recognized for their low noise operation.  A sound attenuated and rugged zincor steel enclosure ensures that the sets are quieter than specified by European sound regulations (OND 2000/14EC).
All models are also compliant with the latest European emission standards.
A spillage-free frame is fitted on all models protecting the environment from inadvertent spills.

Service efficiency – increase 'uptime'

One of Atlas Copco’s focus areas has been to ensure the reliability of the QAS range boosting the customers ‘uptime’ and therefore productivity and revenue.
For the new design particular attention has been given to simplify installation and operation, service and safety.
Large doors and service plates ensure ease of accessibility to all service areas.  Critical service points are all located on one side of the generator (single-sided service point).
The new range also features an extended 500 hour service interval.
A large fuel tank, suitable for a minimum of 8 hours operation at full load is centrally positioned so that regardless of the fuel level, the set remains balanced.

Increased transport efficiency

The compact and sturdy build of the new sets ensures more efficient and safe transportation.  The sets are easy to transport and offer ease of on-site maneuverability.


The redesigned QAS range is ideal for a wide range of demanding construction, rental, contracting and other sophisticated heavy duty applications and particularly where space is a premium.
Featuring a superior standard configuration the new models include integrated forklift slots and a lifting eye for ease of transportation and mobility on-site.
A dual-stage heavy duty air filter and fuel filter with water separation are also fitted as standard. 
A wide range of options are also available to suit each requirement including, for example, paralleling instrumentation for sets above 80 kVA, an integrated 24 hour fuel tank, a trailer with on-highway signalisation and, for refinery operations, a spark arrestor and air shut-off valve.


The lowest cost of ownership together with the highest productivity of the equipment is guaranteed with a full range of Aftermarket solutions developed by Atlas Copco.
These range from maintenance kits for pre-determined service intervals to full coverage service agreements.
Depending on the specific operational set-up and need of the customer, Atlas Copco can propose the most cost-effective solution.
Years of experience and extended field experience, allows Atlas Copco to determine the most optimal service regime.  Atlas Copco’s well trained service technicians rely on the field experience of a worldwide organization and can check the operation condition of the equipment under all circumstances, thus preventing failures and costly down-time by pro-actively replacing wear components.
Atlas Copco’s commitment to quality and reliability can be backed up with an extended warranty program.
