Atlas Copco QAS 235 FD T4F Generator
The Atlas Copco QAS 235 FD T4F generators are prime power, multi-voltage, sound attenuated, mobile generators. They are powered by a FPT 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 with zinc rich primer. 6000 hour salt spray tested. 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.
All QAS generators include the latest Tier 4 Final engine and have a footprint that is up to 20 percent smaller than the previous generation. The starting mechanism ensures that stable power is achieved in less than six seconds.
