A device for separating gas from liquid includes a housing having an inlet for receiving a flow of liquid and gas. The inlet is positioned such that the flow of liquid and gas enters the housing in a direction substantially tangential to a circumference of an inner surface of the housing. The housing also includes a first outlet for discharging an at least partially gaseous flow from the housing and a second outlet for discharging an at least partially deaerated flow of liquid from the housing. The device also includes a gas separating element disposed inside the housing downstream from the inlet and upstream from the second outlet. The gas separating element forms at least one opening to permit liquid to pass and form the at least partially deaerated flow and to permit the at least partially gaseous flow to separate from the at least partially deaerated flow.
