An example device includes a defrothing portion to separate froth into a coalesced fluid and air, an air vent to vent the air from the defrothing portion, and a membrane on an outer surface of the defrothing portion, the membrane sealing the air vent. The membrane is formed of a material to prevent fluid from passing therethrough.
