G 2-7VSD – The superior workshop compressor

Analysis of Oil-Injected Rotary Screw Compressors: G 2-7 VSD Series

The G 2-7VSD – The superior workshop compressor a significant advancement in workshop compressor technology. These oil-injected rotary screw compressors incorporate Variable Speed Drive (VSD) technology, allowing precise adaptation to air demand fluctuations. Unlike traditional fixed-speed compressors that run continuously at full capacity, the VSD units adjust motor speed based on real-time air requirements. This innovation results in more stable pressure, reduced noise levels, decreased component wear, and substantial energy savings—particularly for larger models in the G 5 and G 7 VSD configurations.

Performance Characteristics

The G 2-7 VSD compressors are built for continuous industrial use, maintaining reliable operation even in extreme temperatures up to 46°C/115°F. The IE3 premium-efficiency motor contributes to lower energy consumption while enabling continuous duty cycles without required cool-down periods. The low-vibration screw element minimizes noise, making these units suitable for point-of-use installation near workstations. The belt-driven design further enhances the silent operation, with noise levels as low as 57 dB(A)—comparable to household appliances.

Operational Efficiency

Energy savings of more than 20% are achievable with the G 5 and G 7 VSD models compared to traditional fixed-speed compressors. The state-of-the-art screw element delivers more air with greater efficiency, while the high-quality inverter adapts motor speed to air demand patterns. This adaptive approach not only reduces energy costs but also extends component life by minimizing stress during operation. The compressors feature easily accessible main components, oil separators, and filters, with service intervals extending up to 4,000 hours.

Connectivity and Monitoring

The Elektronikon® Nano™ control system provides intuitive remote monitoring and control capabilities through the SMARTLINK app. This state-of-the-art connectivity allows for advanced management of compressor operations, including real-time notifications and implementation of algorithms like Delayed Second Stop. The system enables users to optimize performance and maintenance schedules remotely, enhancing overall operational efficiency.

Integration and Configuration Options

The G 2-7 VSD series offers flexible installation options with both floor- and tank-mounted models available. Users can choose from different receiver sizes to match specific workshop requirements. A notable feature is the full integration capability of a refrigerant dryer, ensuring dry air output without requiring additional space. High-quality filters are also available to maintain superior air quality for sensitive applications.
