Small Oil-free Wind Cool Dry Screw Vacuum Pump


The dry compound screw vacuum pump is a new type of environmentally friendly vacuum pump developed by our company based on the absorption of many foreign vacuum pumps and using compound screw technology. It has the characteristics of high efficiency, energy saving, environmental protection, light weight, convenient use, and reliable performance. The future development direction of vacuum pumps.

Pharmaceutical technology, chemical technology, solvent recovery, medical equipment, biological products, oil and gas recovery,

Thin film preparation, biochemical detection and analysis, semiconductor, microelectronics, solar energy, material processing and other related equipment and process flow

High initial vacuum (generally the initial vacuum of screw pumps is very low, and the ultimate vacuum can only be reached after a long time of pumping)

Oil-free, water-free and pollution-free, it is very clean, and the pumped materials can be recycled.

Variable pitch energy saving technology can reduce energy consumption

Light weight and low noise
