⚡ WEISIDUN PM VFD SERIES
Permanent Magnet Variable Frequency Air Compressor
WEISIDUN's permanent magnet variable frequency (PM VFD) air compressor features an all‑new design that perfectly combines a high‑efficiency permanent magnet motor with a high‑efficiency air end. By utilizing advanced variable frequency drive (VFD) technology, it significantly reduces customers' operating costs while delivering stable and reliable compressed air.
Why choose a variable frequency air compressor over a fixed‑speed unit? According to industry surveys, the average load rate of industrial air compressors ranges from 60% to 70%. Under such operating conditions, fixed‑frequency (on/off) air compressors have several drawbacks:
- High energy waste during unloaded operation
- Wide pressure fluctuation range – affecting process quality
- Frequent loading/unloading – causing severe wear on mechanical components
How does our permanent magnet VFD compressor solve these problems? The PM VFD model automatically adjusts the compressor's operating speed according to actual air demand at the end‑use point. As a result, the power consumed is linearly proportional to the air output, achieving:
- Stable discharge pressure – no pressure spikes or drops
- Significant energy savings – eliminates power wasted during no‑load running
- Smooth starting – no electrical or mechanical impact, extending equipment life
WEISIDUN PM VFD Series – Smart & Efficient

🌀 WEISIDUN VANE SERIES
Vane Air Compressor
Designed for continuous 24/7 operation · High efficiency · Low oil carryover · Maintenance‑free
Working principle of vane compressor
Filtered by the air filter, air enters the compressor through the suction valve. This valve can adjust the air supply according to demand, thereby maintaining stable working pressure. The rotor rotates eccentrically inside the stator and has vertical slots on its surface, in which the vanes are placed and cling tightly to the inner wall of the stator under centrifugal force. The stator, rotor and vanes form a series of cavities—compression chambers, where air is compressed. Lubrication and cooling are accomplished by a high‑efficiency oil injection system, ensuring excellent process control at low oil consumption. The oil film prevents metal‑to‑metal contact, eliminating wear. As the rotor rotates, the volume of the compression chamber decreases, completing the compression process. The compressed oil‑air mixture has an oil content of less than 3ppm after multiple stages of separation. The separated clean air is cooled by the cooler, and condensed water is discharged through the drain valve.
Key steps of the compression cycle:
- A: Filtered by the air filter, air enters the compression chamber through the suction regulator.
- B: The volume of the compression chamber gradually decreases, and the air is compressed.
- C: Atomized lubricating oil sprayed from the oil injection port enters the chamber, performing cooling, sealing, and lubrication.
- D: The 5‑stage oil‑gas separation system ensures oil content < 3ppm.
- E: The compressed air is cooled by the cooler, outlet temperature only 5–8°C above ambient.
- F: Lubricating oil returns to the compression chamber through cooler and oil filter to start the next cycle.

Air End of scroll compressor
Working principle of oil‑free scroll air compressor
The orbiting scroll rotates in the order of 1-2-3-4 as shown in the diagram, the air is sucked into the space between the orbiting scroll and the stationary scroll, the volume of crescent compression chamber gradually decreases, and then the air is discharged from the exhaust port at the center of the stationary scroll after being compressed.
