Abstract
Filtration systems and methods using a pump and pressure sensor are provided for improved efficiency in fluid filtration systems. A filtration system includes a pre-filter container joined to a post-filter container by a filter line having a filter. To reduce the time required for filtration a pump and pressure sensor are included in a filter inlet flow path. The pump also is used to provide air management in the system via pre-filtration evacuation of air from at least the filter.
Claims20
A filtration system comprising.
- a pre-filter container adapted to contain a fluid;
- a filter;
- a post-filter container adapted to contain a filtered fluid;
- a filter inlet flow path extending between the pre-filter container and the filter;
- a filter outlet flow path extending between the filter and the post-filter container;
- a pump in the filter inlet flow path;
- and
- wherein the pump provides pre-filtration evacuation of air from at least the filter.
