The newly designed rotor profile improves transmission efficiency and reduces energy consumption. A variety of specifications are available. The BS series has positive pressure up to 1500mbar and negative pressure as low as -700mbar, which can meet the requirements of various processes.

The newly designed VRP type pre-inlet Roots vacuum pump and VR type high vacuum Roots pump can be used to transport neutral gases such as air and nitrogen to meet the application needs of vacuum stations, steel plant degassing, coating, packaging, drying and other applications.
