Abstract

The invention is targeted at the process of separating gas, such as air, from a liquid path. Specifically, the invention provides a means to remove gas from a dynamic liquid path, manage the removed gas and liquid path. The invention provides a means to remove gas from a dynamic liquid path using the buoyant property of gas in a less buoyant liquid, having a single-plane ingress and egress ports for liquid and gas flow, separate points of egress for liquid and trapped gas and integral liquid channels.
