Description

Advantages

GC Roots vacuum pumps are designed to create high and medium vacuums. The working principle of the Roots pump is based on the intake and exhaust of gas due to the rotation of two rotors inside the pump. The Roots pump cannot discharge gas directly into the atmosphere; therefore, it is typically used in conjunction with a support pump.

Some potential applications for Roots pumps include:
• Gas removal by vacuum
• Vacuum melting
• Vacuum processing of molten steel
• Vacuum heat treatment in the metals industry
• Chemical industry
• Medical applications
• Food production
• Engine manufacturing, etc.
