A novel inlet and baffle structure for a drilling and degasser is provided. Gas-cut mud is fed into the degasser vacuum chamber through a horizontal inlet pipe having a long slot cut in its bottom wall. The mud flow is formed into a thin curtain as it passes through this slot. At the same time, its rate of movement is accelerated, with a consequent increase in shear and drop in viscosity. The mud immediately contacts a generally horizontal baffle. The flow is divided into two turbulent, thin layers. It is then conducted through a system of baffles. Due to the change in mud viscosity, induced turbulence and the forming of the mud flow into thin layers of large area, the vacuum within the chamber is able to effectively separate the entrained gas from the mud.
