The Atlas Copco QAS 330 JD T4F generators are prime power, multi-voltage, sound attenuated, mobile generators. They are powered by a JD T4 Final liquid-cooled, six-cylinder diesel engine.
The units consist of an alternator, diesel engine, cooling system, electrical distribution and control systems - all enclosed within a sound attenuated enclosure fabricated from powder coated steel.
A broad range of undercarriage formats and options are available.
Special attention has been given to the overall product quality, user friendliness, ease of serviceability, and economical operation to ensure best in class total cost of ownership.

Mobile hospitals and supply units heavily rely on generators such as our QAS 330 generator. A stable power source can make all the difference, and with marine grade protection and high overload capacity, this generator is always reliable.
In mining fields, diesel has a lower volatility rate than gasoline, making it a safer alternative to gasoline. Our QAS diesel generators from 250 to 700 kVA are always the number one option when working with mining materials such as coal, iron, or precious metals since it’s portable and can be used in remote areas with extreme conditions.
In a time of power outages or when a power grid connection is compromised, diesel generators may be used by residential, commercial, and municipal areas. Whenever you need extra power, Atlas Copco's generator can provide it, so life can continue on as normal.
