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.
