Abstract
A filter assembly for removing particulate matter, bacteria and air from a liquid. The filter assembly comprises a housing having an inlet for receiving the liquid within the housing and an outlet to provide an exit for the liquid. All of the liquid entering the housing passes through a primary filtration stage that contains a hydrophobic filter arrangement for venting air in the liquid to the atmosphere and a depth filter arrangement for filtering particulate matter in the liquid. Alo disposed in the housing is a secondary filtration stage through which all of the liquid passes after leaving the primary filtration stage. The secondary filtration stage includes a hydrophobic filter arrangement for venting any remaining air in the liquid to the atmosphere and a final filter for removing bacteria from the liquid.
