W Type of Medium-High Pressure Oil-Free Air Compressor
- Low speed: starting from 355 to 460 rpm reduce wear.
- Long stoke: 10 to 30% more than similar industries.
- Low piston load: smaller piston diameter, reduce load on components.
- Low discharge temperature: operate temperature within 90°c-130°c improved relaibility.
- Improved compression: additional 1 to 3 ring to reduce compression leakage.
- Low vibrition: precision balance inertia force and torque to achieved dynamic balance.
- High volumatic efficiency: achieved isobaric condition with equal pressure ratio on each stage.
- Compression design: 3-stages with double acting on stage one and combination single acting on stage two & three.
- High efficient cooler: providing compression cycle closed to isothermal condition, reduces energy loss.

V Type of Medium-High Pressure Oil-Free Air Compressor
