Pioneered by Atlas Copco, VSD compressors match their motor speed to the fluctuations in users’ air demand. This flexibility stands in contrast with the traditional fixed-speed compressor, which always runs at 100%, even when the user doesn’t need it to. Long available in most industrial compressor sizes, VSD models outperform their fixed-speed counterparts on every important benchmark, including performance, reliability, and efficiency. The G 2-7 VSD now makes these benefits available, for the first time ever, for the 2-7 kW compressor customer.

The G 2-7 VSD offers a greater compressed air output and a more stable pressure than its fixed-speed alternative. In addition, Atlas Copco’s patented screw element ensures a 100% duty cycle. This means that, as opposed to the piston compressors often used in workshops, it does not require cool-down periods and work interruptions.

The G 2-7 VSD’s gradual start-up ensures lower starting currents and less stress on bearings and belts. As result, these key components typically last longer and require less maintenance. And when service is needed, all G 2-7 VSD compressors come with panels that make the main components easily accessible.

Thanks to the lower speeds of the element and the motor-mounted fan, the G 2-7 VSD only produces as much noise as a household appliance. Coupled with their compact size, this means they can be installed near the point of use. That is extremely beneficial for smaller operations that have limited space available.

Fixed-speed models operate at maximum energy use, even when operators don’t need its maximum capacity. VSD technology eliminates this energy waste by matching the motor speed to the air demand. For the G 5 and 7 VSD, this can mean reduced energy consumption and costs by more than 20%.

Customers can customize their G 2-7 VSD to their specific needs with a range of options. For those who need dry, clean air, the Full Feature model comes with a fully integrated dryer. A tank-mounted version offers air storage.

The G 2-7 VSD features the state-of-the-art Elektronikon® NanoTM controller. With a smartphone or a tablet, users can start and stop their compressor and monitor its pressure, temperature, running hours and operation mode from anywhere. Nano controllers also offer advanced control algorithms and a leakage protection program. Finally, the Nano can securely receive over-the-air updates, ensuring that customers never miss out on new features and other performance advancements.

The G 2-7 VSD is available for order worldwide today.
