2600, 4200 m3/h fluid coupling roots vacuum pump is a type of mechanical pump that is designed to increase the speed and efficiency of vacuum systems. It operates using a hydraulic coupling to power a set of rotors or impellers, which move air or gas molecules from the inlet side to the outlet side.

100, 250, 500, 1000 m3/h Direct Coupling Roots Vacuum Pump is a larger capacity pump that can handle a wide range of pumping speeds from 100 to 1000 cubic meters per hour. It is designed for heavy-duty industrial applications, such as vacuum furnace degassing, vacuum metallurgy, and chemical vapor deposition.
