The Scroll Vacuum Pump is designed around a smooth, oil-free compression mechanism that delivers high efficiency, low noise, and reliable performance. Its working principle is simple yet highly effective: air is first drawn in and completely sealed within the volume chamber, where compression begins. As the scroll elements move, compression continues gradually toward the center of the chamber, ensuring stable and vibration-free operation. The air is then fully compressed at the center point, where exhaust starts, and once the exhaust is completed, a full compression cycle ends. This continuous and uniform process results in clean vacuum generation with minimal wear. Thanks to these advantages, scroll vacuum pumps are widely used in applications such as laboratories, medical equipment, semiconductor processing, analytical instruments, and packaging systems, where quiet operation, oil-free performance, and high reliability are essential.
1. Air is drawn in and completely sealed within the volume chamber; compression begins;
2. Compression continues gradually towards the center point of the volume chamber;
3. The air is compressed to the center point of the volume chamber, and exhaust is about to begin;
4. Exhaust is completed, and a complete compression cycle ends.
