1. A vacuum is generated by driving with compressed air. No electricity is required and can be used in explosion-proof areas.

2. No heat. The normal operating temperature is - 20 ℃ ~ + 120 ℃.

3. Save energy. The ratio of compressed air consumption to vacuum pumping capacity can reach 1:3 at most. After the throttle valve is installed, the compressed air can be saved and the vacuum degree can be reduced.

4. Small size and light weight. Easy to install in a narrow space.

5. Low noise. Compared with the vacuum pump with the same flow rate, the noise is only 53db-56db.

6. No vibration. It is widely used in spaces where vibration needs to be avoided.

7. No lubrication is required and there are few hidden troubles. Therefore, no maintenance is required, unlike the motor-driven vacuum pump, which requires regular maintenance.

8. Fast response speed, suitable for frequent startup. The reaction speed of the corresponding vacuum pump is very slow.

9. Strong environmental adaptability. The vacuum generator made of corrosion-resistant materials is suitable for corrosive and dangerous environments.

10. There are many flow rates and vacuum degrees to choose from. Flow range: 8L / min ~ 11928l / min. The maximum vacuum can reach - 100. 8kPa（-756mmHg）。

11. Low cost. Equivalent to about one third of the price of the vacuum pump with the same flow. And there is a large amount of stock.
