Dry vacuum pump is mainly divided into two types: dry screw vacuum pump and dry scroll vacuum pump. The following section introduces the price of these two dry vacuum pumps.
Dry screw vacuum pump began to be used in the 1980s, initially in the semiconductor industry, and in the early 1990s in the chemical industry. Its main features are as follows:
1. No pollution to process gas
2. No waste water is produced.
3. No vacuum oil consumption, no soot emission
4. It can recover the extracted medium and condensate various solvents.
5. Achieving a Higher Vacuum
6. Low maintenance and cost
