Answer: No, the GWL Series compressor has a reasonable structure and only generates rotational force during operation, without radial and axial forces.
Answer: The isothermal compression is achieved through the use of water lubrication, which helps to dissipate heat more effectively.
Answer: It can be determined by observing the pressure differential indicator of the water filter or based on usage time and water quality.
Answer: Water lubricates the screw elements, cools the compressor, and helps to maintain optimal operating conditions.
