Embodiment Construction

[0036] The present invention discloses modular filter-in-filter units, ie, an outer filter unit and an inner filter unit, that can be assembled to form filter cartridges for use in separate methods and systems. The modular filter-in-filter units and filter cartridges assembled therefrom can be further described as follows.

[0037] The outer and inner filtration units comprise or utilize media comprising one or more layers of media material for filtering a mixture of continuous and dispersed phases and coalescing the dispersed phase. Such media may be referred to herein as "coalescing media materials." As referred to herein, one or more layers may have a desired pore size, porosity, and fiber diameter. One or more layers may be homogeneous (ie, comprise one material) or heterogeneous (ie, comprise hybrid materials). The terms "pore size," "porosity," and "fiber diameter" may refer to the "average" or "average" value of these terms (e.g., if a layer is heterogeneous or graded...

Abstract

Disclosed are modular filter-in-filter elements, namely an outer filter element and an inner filter element which may be assembled to form a filter cartridge for use in separation methods and systems. The outer filter element typically functions as a coalescing element and the inner element typically functions as a particulate filter element. The disclosed filter cartridges may be structured for separating water from a hydrocarbon-based liquid fuel as the fuel moves through the cartridge from outside to inside.

Description

technical field [0001] The field of the invention relates to filters, such as filter-in-filter cartridges for fuel-water separation. In particular, the field relates to filter-in-filter fuel-water separators and particle filters, preferably comprising thermoplastic materials. [0002] The subject matter of this application is related to U.S. Patent Application No. 12 / 820,791, filed June 22, 2010, entitled "Modular Filtration Unit for Use in Filter-in-Filtration Cartridges," and filed June 22, 2010 to the title US Patent Application No. 12 / 820,784 for "Two-Stage Water Separator and Particle Filter," to which this application claims priority from both of the aforementioned applications, the entire contents of which are incorporated herein by reference. Background technique [0003] Coalescers are widely used to remove immiscible droplets from gaseous or liquid continuous phases, such as in crankcase ventilation (CV) filtration, fuel water separation (FWS) and oil-water separa...
