Abstract
A method for clearing a wetted hydrophobic filter includes a first step in which the air permeability of the hydrophobic filter is monitored, and a second step in which the hydrophobic filter is cleared by means of a connected air pump, if it is detected that the hydrophobic filter is clogged. An apparatus for performing this method includes a pressure sensor and an air pump connected to an air separation chamber via a conduit, and a control and monitoring unit configured to actuate the air pump in order to clear the hydrophobic filter.
