Abstract
A filter cartridge with easier extraction provided by a roll-out clearance region for a radial seal is provided. The filter cartridge may be a two stage filter with the seal being located between stages and usable in a filtration vessel having a central separation wall with one or more riser pipes. Also, a new vessel is disclosed with multiple diameters for first and second stages of the housing with a larger second stage diameter as compared to the first stage, which can reduce door size and/or cause fluid flow velocities to be slower at the second stage relative to the first stage.
Claims23
A filter cartridge, comprising:
- a filter media tube;
- a seal holder mounted to the filter media tube,
- a seal ring supported by the seal ring holder and facing radially outwardly, the seal ring being a radial seal including seal flange having an annular shape and projecting radially outwardly;
- and
- a roll-out clearance region provided by the seal ring holder on one side of the seal flange.
A filter cartridge for use with a filtration assembly having a first filtration assembly stage and a second filtration assembly stage and a filter sealing sleeve, comprising:
- a filter media tube;
- a seal holder mounted to the filter media tube to separate the filter media tube into a first stage and a second stage,
- a seal ring supported by the seal ring holder and facing radially outwardly, the seal ring being a radial seal for radially sealing against the filter sealing sleeve;
- and
- means along the seal holder and along the second stage for reducing extraction force by at least partly receiving the seal ring in a rolled over condition during removal of the filter cartridge from the filter sealing sleeve.
