Abstract
A filter bag assembly includes a flexible bag bounding a compartment that is configured to hold a fluid. An inlet port and an outlet port are each secured to the flexible bag so as to communicate with the compartment. A porous filter sheet is disposed within the compartment of the flexible bag so that fluid entering the compartment through the inlet port must pass through the filter sheet before exiting the compartment through the outlet port. A first retention seal secures the porous filter sheet to a portion of the flexible bag within the compartment, the first retention seal having an outer perimeter edge that forms an annular continuous loop.
Claims18
A filter bag assembly comprising:
- a flexible first sheet;
- a flexible second sheet overlying and secured to the first sheet so that a main compartment is formed therebetween;
- a porous filter sheet disposed between the first sheet and second sheet so as to divide the main compartment into a first compartment and a second compartment, the first compartment and the second compartment being entirely disposed on opposing sides of the porous filter sheet, the porous filter sheet being configured to filter a fluid passing between the first compartment and the second compartment;
- a first port secured to the first sheet or the second sheet and communicating directly with the first compartment;
- a first retention seal securing the second sheet to the filter sheet so that at least a portion of the first compartment bounded between the second sheet and the filter sheet encircles the first retention seal;
- and
- a second port secured to the first sheet or the second sheet and communicating directly with the second compartment, the second port being spaced apart from the first retention seal so that the second port is not encircled by the retention seal.
