An oil-free screw air compressor doesn't mean there's absolutely no oil inside the machine.
As industrial energy-saving upgrades become increasingly widespread, market demand for energy-saving oil-injected screw air compressors continues to rise.
Air compressors rated for 20–30 bar (equivalent to 2–3 MPa) are classified as medium-to-high-pressure industrial equipment.
Operation, maintenance, and servicing of the air compressor and its components must be performed by qualified personnel.
A variable frequency drive (VFD) air compressor is an energy-saving device that dynamically adjusts the speed of the main unit by using a frequency
Excessive system pressure. An emergency shutdown occurs, triggering gas venting or recirculation; the discharge check valve
