Abstract

An apparatus, a system and a method for venting a gas from a liquid delivery system are provided. A venting tube may be provided and may be positioned within a chamber that contains the liquid. The liquid may have a top surface within the chamber. The venting tube may have an opening covered by a liquiphobic membrane or a hydrophobic membrane. The membrane may define a plane or a surface which is not parallel to the top surface of the liquid. Gas may pass through a portion of the membrane into the venting tube. Moreover, the membrane may vent the gas. The membrane is non-parallel to the liquid, and, as a result, the membrane may be less prone to clogging.
