An aqueous fluid filter assembly with aeration mitigation includes a cap, a bowl engaging the cap and defining a filter volume, and a filter element disposed in the filter volume. The filter element is sealed against an interior of the cap and an interior of the bowl to provide an unfiltered volume and a filtered volume. An inlet is in fluid communication with the unfiltered volume and an outlet is in fluid communication with the filtered volume via a pickup section. The pickup section has a pick-up section inlet extending into the filtered volume and an air-metering orifice, wherein the air-metering orifice has a diameter less than 30% of the diameter of the pick-up section inlet and the pick-up section inlet is located below the air-metering orifice.

Various example embodiments relate to a filtration system. The filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing comprises a key slot disposed on the first housing end and a housing key element protruding from the first housing end toward the second housing end. The filtration system further comprises a filter element positioned within the central compartment of the housing. The filter element has a first filter end and a second filter end. The filter element includes filter media and an endplate disposed on the first filter end. The endplate includes a central endplate opening, a key element configured for engagement with the key slot, and an installation guidance element formed along the central endplate opening. The installation guidance element is configured for engagement with the housing key element.

A ring filter element for a filter device may include a connecting region and an axially projecting pin. The pin may include an arm via which the pin is connected to the connecting region. The arm may include a predetermined breaking point disposed spaced apart from the connecting region.

A filter is used for removing metallic contaminants in a solvent used in microcircuit fabrication. The filter includes a filter housing including a filter membrane for filtering solvent including metallic contaminants, and a magnet arranged about the filter housing and configured to generate a magnetic field to attract the metallic contaminants prior to the metallic contaminants entering the filter membrane. The magnet is arranged such that the magnetic field of the magnet is greater in a periphery of the filter housing compared to a central portion of the filter housing.

A filter unit is disclosed that increases solids loading capacity, decreases specific flowrate during filtration, and improves backwash effectiveness. A flow shaping plate and/or flow diverting member are used to reduce flow entrance effects during reverse, backwash flow through the filter unit.
