ABSTRACT OF THE DISCLOSURE A liquid seal assembly for a gas flow system having a housing containing a water seal, a vertically directed cylindrical pipe for gas entry dipping into the water and a second smaller cylindrical pipe, coaxial with the first, also dipping below the water level. Communication between the annulus between the first and second cylindrical pipes to the inside of the second pipe, is by means of one or a plurality of nested annular cups. These are below the normal static water level and are thus filled with water whenever the pressure of incoming gas is below a selected value. As the pressure of the incoming gas increases, the water level is depressed until gas can flow through the U-shaped passage of one of the annular cups. If entering gas is not water saturated, it will pick up the water in the cup and, as flow continues, the cup then essentially becomes dry and there is no further loss of water from the bath. When the pressure again drops below the selected level, the water level in the seal rises and floods the cups so as to provide the water seal.
