GWV Series
GWV Series Smart Variable-Speed Water-Lubricated Oil-Free Screw Air Compressor
The GWV Series smart variable-speed water-lubricated oil-free screw air compressors combine a water-lubricated oil-free screw compression system with variable-speed operation. The series is designed for industrial compressed air systems with fluctuating air demand, allowing equipment to be configured according to different compressed air requirements.
The series is available in multiple power ratings, with corresponding volumetric flow ranges specified for operating pressures such as 0.8 MPa, 1.0 MPa, and 1.25 MPa. Rather than specifying a single fixed flow value, the GWV Series product data provides FAD ranges for different models, making it easier to select equipment according to the actual load range.
In addition to working pressure and flow range, the specification table provides data on motor power, noise level, cooling water inlet and outlet connection sizes, cooling water requirements, lubricating water requirements, overall dimensions, weight, and air outlet connection size. These specifications can be used as a reference for equipment installation and compressed air system configuration.

Note: This table has been reconstructed from the original GWV documentation using a “one model per row” format. For each model, the 0.8 / 1.0 / 1.25 MPa pressure ratings and their corresponding FAD ranges are arranged vertically within the same cell. For the GW250VW and GW264VW models, the cooling-water-related columns contain two rows of data in the original table. However, the original page does not clearly indicate how these two rows correspond individually to the three pressure conditions. Therefore, the two rows have been retained as presented in the original documentation without making any additional assumptions.
Selection Guide
GWV Series model selection should primarily be based on the actual operating pressure and the range of variation in compressed air demand.
First, determine the system's continuous operating pressure, then check the FAD range of each model at the corresponding pressure. The normal air demand should fall within the effective flow range of the selected model, while peak air demand should also be taken into account.
If the system's air demand remains relatively stable over extended periods, avoid oversizing the equipment simply because it features variable-speed operation. If air demand fluctuates significantly, particular attention should be paid to whether the minimum, typical, and peak air demands fall within an appropriate FAD range.
Finally, verify the c
