The Vacuum Degasser is designed to remove harmful entrained gases from drilling fluids in solids control systems. By applying vacuum pressure, the equipment efficiently separates gas from the drilling mud, restoring mud density and improving drilling safety and circulation performance.
It is typically installed after the shale shaker and before the desander/desilter in the drilling fluid circulation system. The vacuum degasser is widely used in oil & gas drilling, geothermal drilling, HDD drilling and drilling fluid recycling systems.

Main Features
Working Principle
Gas-cut drilling mud enters the vacuum chamber, where negative pressure rapidly separates free and entrained gas from the drilling fluid. The separated gas is discharged through the vacuum system, while the degassed drilling fluid is pumped back into the active mud system for further processing.
