Abstract
Fluid filtration systems and methods thereof to filter fluid in a first directional mode and a second directional mode are disclosed. Fluid filtration systems and methods thereof include a first directional mode, a second directional mode, and a filter unit. The filter unit includes a filter housing unit and a filter chamber disposed in the filter unit.
Claims2
A method of filtering fluid in a first directional mode and in a second directional mode, the method comprising:
- selectively transporting fluid through porous adsorbent material in a filter chamber of a filter housing unit of a filter unit to establish a first flow pattern in at least a first direction in the first directional mode to filter the fluid selectively transported in the at least first direction;
- selectively transporting fluid through the porous adsorbent material in the filter chamber to establish a second flow pattern in at least a second direction in the second directional mode to filter the fluid selectively transported in the second direction such that the at least first direction is different than the at least second direction;
- selectively transporting fluid to a first port of the filter unit and subsequently from a second port of the filter unit in the first directional mode;
- and
- selectively transporting fluid to the second port and subsequently from the first port in the second directional mode such that the fluid includes carrier oil.
