GWV-2 series
GWV-2 Series Energy-Saving Two-Stage Compression Permanent Magnet Variable-Speed Oil-Free Screw Air
The GWV-2 Series Energy-Saving Two-Stage Compression Permanent Magnet Variable-Speed Oil-Free Screw Air Compressors feature a two-stage compression design and permanent magnet variable-speed operation. The series is designed for industrial applications requiring oil-free compressed air, a range of operating pressures, and load regulation.
The series offers various motor power configurations to accommodate different volumetric flow rates and working pressures. The specification table covers multiple free air delivery (FAD) ratings, including 8, 10, 12, 14, 16, 20, 24, 30, and 40 m³/min, with different pressure ratings ranging from approximately 1.0 to 2.0 MPa.
The product documentation also provides specifications for cooling water requirements, lubricating water requirements, equipment dimensions, weight, and air outlet connections, facilitating equipment selection and layout planning based on the requirements of the compressed air system.

Note: This table has been extracted from the original GWV-2 product documentation and follows the grouped web table structure used in the existing product specification tables. Within each FAD group, the models, motor power ratings, maximum working pressures, and weights are listed vertically in the corresponding order shown in the original table. For the FAD 16 and FAD 40 groups, the air outlet connection sizes are displayed on two lines in the original table. However, the original documentation does not explicitly specify which connection size corresponds to each model. Therefore, these entries have been preserved exactly as presented, without making any additional assumptions.
Selection Guide
GWV-2 model selection should take into account the required pressure, free air delivery (FAD), and actual load variations.
First, determine the pressure rating based on the pressure required by the equipment at the point of use. Then select the appropriate FAD rating according to the normal and peak air demand.
For systems with significant load variations, particular attention should be paid to the motor power configurations available within each FAD group and the actual operating requirements. For systems with consistently stable loads, unnecessary oversizing should be avoided.
The specific operating configuration, control logic, and energy savings of a two-stage compressor depend on the actual operating conditions. Therefore, a fixed energy-saving percent
