Typical Type Of Vacuum System

- Jun 30, 2018-


The system that used to meet certain process requirements, capable of obtaining and measuring the specific required vacuum is called vacuum system. A more complete vacuum system consists of vacuum chamber, required vacuum pump or vacuum unit, vacuum measurement device, connection conduit, vacuum valve, trap and other vacuum components and electrical control system. Typical vacuum system is shown in Fig.1 and Fig.2.
