GWVH Series
GWVH Series Smart Variable-Speed Water-Lubricated Oil-Free Medium-Pressure Screw Air Compressor
The GWVH Series smart variable-speed water-lubricated oil-free medium-pressure screw air compressors are designed for medium-pressure air supply applications requiring pressures higher than those of conventional industrial compressed air systems. The series features a water-lubricated oil-free screw compression system with variable-speed operation.
The series is primarily available in working pressure ratings of 2.5 MPa, 3.0 MPa, and 4.0 MPa, with different models configured to provide corresponding volumetric flow rates. The technical specifications cover FAD operating conditions ranging from approximately 5 to 40 m³/min, allowing model selection based on the required pressure, flow rate, and equipment power.
The product documentation also provides specifications for noise levels, cooling water inlet and outlet connection sizes, cooling water requirements, lubricating water requirements, overall dimensions, weight, and air outlet connection size. These parameters serve as a reference for equipment layout and piping design in medium-pressure compressed air systems.

Note: This table has been extracted from the original GWVH product documentation and reconstructed using a “one row per FAD operating condition group” format. Model numbers, motor power ratings, maximum working pressures, and weights are arranged vertically within their respective cells, maintaining the original order and correspondence. For the GW165VWH-25 / GW185VWH-30 / GW207VWH-40 group, the original table lists two rows of overall dimensions, which have been retained exactly as presented. In addition, the model suffixes and corresponding pressure values for GW222VWH-40 and GW250VWH-25 do not appear to follow the usual suffix convention. No corrections or assumptions have been made, and the original data has been preserved.
Selection Guide
The GWVH Series is designed for medium-pressure applications. Model selection should begin by determining the actual pressure required at the point of use.
The required equipment inlet pressure, pressure losses in the distribution piping, and allowable system pressure fluctuations should all be considered before selecting a 2.5, 3.0, or 4.0 MPa model. Selecting the highest pressure rating by default is not recommended.
Once the required pressure has been determined, select the appropriate operating condition group and specific model based on the required FAD. The motor power configuration, cooling water requirements, and pipe connection sizes should also be verified.
As medium-pressure systems impose higher pressure-rating requirements on piping, valves, ai
