Abstract (en)

[origin: WO9932206A1] Filter assembly (100) for filtering pressurized fluid removed from a fluid system having undesirable levels of contamination, such as a dry cleaning system. The filter assembly (100) has an upstream connection (110) in fluid communication with the fluid system to remove contaminated pressurized fluid therefrom. A plurality of filter lines (120, 130, 140) are in fluid communication with the upstream connection (110). The plurality of filter lines are connected in parallel with each other for concurrent flow of the pressurized fluid therethrough. Each filter line has a strainer (122) and at least one insoluble contaminant filter connected in series (124). Additional filter elements may be provided. The filters have housings with cross-dimensions substantially similar to those of the filter lines and the other piping used throughout the fluid system. A downstream connection (150) is provided in fluid communication between the filter lines and the fluid system such that pressurized fluid removed from the fluid system flows from the upstream connection (110) and in parallel through the filter lines (120, 130, 140) before returning to the fluid system through the downstream connection (150).
