Abstract
A filter system comprises a pressure vessel housing with internal components designed to remove solid particles, semi-solid particles, and liquid droplets from a gas phase media. The filter housing utilizes multiple replaceable filter cartridges. The system includes a keyed filter coalescer cartridge designed to flow from the inside open area of the cartridge to the outside annular area of the housing prior to leaving the system through an outlet nozzle. The key is designed to locate a baffle of the filter cartridge inlet side end cap in a certain orientation as to provide enhanced liquid removal performance for the system. The baffle may also serve as a handle.
Claims39
A filter cartridge, comprising:
- a tubular ring of a filter media surrounding a central cavity, the tubular ring extending around a central axis between an inlet end and an outlet end;
- an outlet end cap secured to the outlet end of the tubular ring, the outlet end cap including a cover portion closing the central cavity at the outlet end;
- and
- a projection projecting from the cover portion toward the inlet end into the central cavity, the projection intersecting the central axis and including an annular wall defining a socket, the annular wall having an interruption along an inner periphery thereof providing a key.

A filter cartridge, comprising:
- a tubular ring of a filter media surrounding a central cavity, the tubular ring extending around a central axis horizontally between an inlet end and an outlet end;
- an outlet end cap secured to the outlet end of the tubular ring, the outlet end cap including a cover portion closing the central cavity at the outlet end;
- an inlet end cap secured to the inlet end, the inlet end cap defining a flow opening entering into the central cavity;
- and
- a baffle at the inlet end cap, the baffle arranged relative to the flow opening to direct fluid flow away from a gravitational bottom of the tubular ring of the filter media.
2 more elements
A filter assembly comprising:
- a housing comprising a pressure vessel and a door, the pressure vessel including a horizontally extending tubular wall and having an inlet port, an outlet port and an access port at one end of the horizontally extending tubular wall, the door mounted to the pressure vessel, the door having an open position allowing access into the pressure vessel and a closed position sealing shut the access port;
- a partition internally mounted within the horizontally extending tubular wall, the partition having a plurality of filtration openings, and dividing the pressure vessel into an inlet side and an outlet side, the access port being at the inlet side;
- an outlet grid internally mounted within the horizontally extending tubular wall in horizontally spaced relation from the partition;
- a plurality baskets, each filter basket mounted in a corresponding respective member of the filter openings and mounted to the outlet grid, each basket comprising:
- (a) a ring mount including a solid tubular portion, (b) a perforated cylindrical tube, and (c) a basket cap mounted to the outlet grid;
- wherein the ring mount and the basket cap are secured to opposing ends of the perforated cylindrical tube;
- a plurality of filter cartridges, each filter cartridge removably mounted in a corresponding respective member of the baskets, with a seal sealing between the ring mount and the inlet end cap, each filter cartridge comprising:
- (a) a tubular ring of a filter media surrounding a central cavity, the tubular ring extending around a central axis horizontally between an inlet end and an outlet end;
- (b) an outlet end cap secured to the outlet end of the tubular ring, the outlet end cap including a cover portion closing the central cavity at the outlet end;
- and (c) an inlet end cap secured to the inlet end, the inlet end cap defining a flow opening entering into the central cavity;
- and
- a removable backflow plate arranged upstream of the partition between the partition and the access port, the backflow plate arranged in close proximity the filter cartridges to prevent the filter cartridges from dislodging and/or unsealing from the ring mount in the even of a back-pulse, the back flow plate further comprising:
- (a) a plurality of flow apertures, each flow aperture axially aligned with the flow opening of a respective member of the filter cartridges,
- (b) a plurality of flow baffles, each flow baffle along a corresponding respective member of the flow apertures and arranged along a bottom portion thereof, wherein the flow baffles direct fluid flow away from a gravitational bottom of the filter cartridges.

A filter cartridge for installation within a housing, the filter cartridge comprising:
- an elongated, cylindrical filter media body circumscribing a central cavity;
- a first end cap at one end of the body, the first end cap including a projection extending outwardly away from the end cap, the projection including a geometry for engagement with the housing when the cartridge is installed into the housing to rotationally orient the cartridge relative to the housing;
- and
- a second end cap at another end of the body, the second end cap including a peripheral body portion defining a central opening into the central cavity, the peripheral body portion having a ledge projecting across a segment of the central opening, the ledge having a predetermined relationship with the projection such that the ledge is positioned toward a lower side of the cartridge when the cartridge is installed within the housing.
