GW Series Smart Water-Lubricated Oil-Free Screw Air Compressor

The GW Series smart water-lubricated oil-free screw air compressors use a water-lubricated screw compression system and are designed for industrial applications requiring oil-free compressed air. The series covers a range of power ratings and air delivery capacities, allowing the appropriate model to be selected according to the required operating pressure, flow rate, and on-site installation conditions.

The GW Series is available with working pressures of 0.8 MPa, 1.0 MPa, and 1.25 MPa, with motor power ratings ranging from 7.5 to 250 kW. Different models feature different volumetric flow rates, cooling water requirements, lubricating water requirements, dimensions, weights, and piping connections, making them suitable for compressed air systems of various capacities.

For actual projects, the basic model can be selected according to the required continuous operating pressure and volumetric flow rate, followed by configuration based on cooling conditions, available installation space, and piping connections. The final equipment model and technical configuration should be determined according to the actual operating conditions and the project's technical confirmation.

Note: This table has been reconstructed based on the visual structure of the original material, with one model per row. For each model, the 0.8 / 1.0 / 1.25 MPa pressure ratings and their corresponding FAD values are arranged vertically within the same cell. The rowspan attribute is no longer used, eliminating gaps in horizontal borders caused by row-spanning cells.

Selection Guide

When selecting a GW Series model, the actual working pressure and required volumetric flow rate should be determined first. The FAD of the same model varies at different operating pressures. Therefore, the flow rate corresponding to the continuous operating pressure should be used as the primary basis for model selection, rather than selecting a model based solely on motor power.

After determining the required pressure and flow rate, the motor power, cooling water inlet and outlet connection sizes, cooling water requirements, lubricating water requirements, overall dimensions, weight, and air outlet connection size should also be checked.

For systems operating continuously or with significant fluctuations in air demand, the required capacity should be determined by c
