ABSTRACT:
A device for reducing the amount of a gas contained in a liquid includes a central core with an inlet channel, an outlet channel, and a transverse channel. A first chamber is formed on a first side of the core for receiving the liquid from the inlet channel, and a second chamber is formed on the opposite side of the core for receiving the liquid after it has passed through the first chamber. Each of the chambers includes a hydrophobic membrane for allowing gas that has separated from the liquid to pass to the atmosphere. The two chambers are arranged such that gas escaping from the liquid rises to the top of at least one of the chambers for any orientation of the device. The device, accordingly, is not dependent on orientation for effectiveness.
