ABSTRACT:
A filter consisting of connected upper housing and lower housing parts and a hydrophobic flat filter disc for gas filtration sandwiched therebetween, intended in particular for an exchange between a container such as a liquid reservoir partially filled with liquid and the surrounding atmosphere. The upper housing part includes an integral channelled filter support having channels for communication into a gas inlet-outlet means of the said upper housing part. The lower housing part includes an integral, channelled filter support having channels for communication into a centrally disposed bore located at a right angle to the filter support and empties into the gas area of a liquid reservoir for instance. The filter support is constructed to prevent liquid from completely blocking the hydrophobic filter disc.
The filter support of the lower housing forms a planar plane with an annular channel therein and a series of radially extending channels terminating at a centrally located bore. The channels having a controlled depth. The bore diameter is also controlled. The upper housing is dimensioned to provide a controlled distance for the filter from the filter support in the lower housing.
