Filter assembly for separating water from fuel

An equipment system, comprising:

• a fuel delivery line;
• an engine disposed at an end of the fuel delivery line;
• and
• a filter assembly disposed within the fuel delivery line upstream from the engine, wherein the filter assembly is configured to prevent water from infiltrating the engine, the filter assembly comprising:
• a housing including a fuel inlet line and a fuel outlet line, wherein the housing defines an internal chamber in fluid communication with the fuel inlet line and the fuel outlet line, wherein the housing is configured to allow fuel to pass into the internal chamber through the fuel inlet, and to allow filtered fuel to pass out of the internal chamber to the engine through the fuel outlet line;
• a filtering frame secured within the internal chamber, wherein the filtering frame includes a coalescing frame portion that is configured to allow water to coalesce thereon and sink toward a bottom of the internal chamber, wherein the coalescing frame portion comprises a first rim defining a first central opening connected to an opposed second rim defining a second central opening through a plurality of spaced-apart extension beams, and a hydrophobic frame portion that is configured to repel the water, wherein the hydrophobic frame portion includes a valve, wherein the valve is coupled to the fuel outlet line, wherein the hydrophobic frame portion further includes a plurality of inwardly-canted beams that inwardly cant and extend from the first rim and connect to the valve, wherein the valve comprises a central hub having a valve passage formed therethrough;
• and
• a flow restrictor that is configured to float on the water toward the valve, wherein the flow restrictor sealingly engages the valve to prevent fluid from flowing through the valve when a surface level of the water is proximate to the valve.

A filter assembly configured to prevent water from infiltrating one or both of a fuel tank or engine, the filter assembly comprising:

• a housing including a base connected to a cap, wherein the base includes a support floor, and wherein the cap includes a fuel inlet line and a fuel outlet line, wherein the base and the cap define an internal chamber that is in fluid communication with the fuel inlet line and the fuel outlet line, wherein the housing is configured to allow fuel to pass into the internal chamber through the fuel inlet, and to allow filtered fuel to pass out of the internal chamber to the fuel tank or the engine through the fuel outlet line;
• a filtering frame secured within the internal chamber, wherein the filtering frame consists of (a) a coalescing frame portion that is configured to allow water to coalesce thereon and sink toward a bottom of the internal chamber, wherein the coalescing frame portion consists of a first rim defining a first central opening connected to an opposed second rim defining a second central opening through a plurality of spaced-apart extension beams, and (b) a hydrophobic frame portion that is configured to repel the water from a valve, wherein the valve is coupled to the fuel outlet line, wherein the hydrophobic frame portion consists of a plurality of inwardly-canted beams that connect to the valve, wherein the valve comprises a central hub having a passage formed therethrough;
• and
• a flow restrictor that is configured to float on the water toward the valve, wherein the flow restrictor sealingly engages the valve to prevent fluid from flowing through the valve when a surface level of the water is proximate to the valve, wherein a specific gravity of the flow restrictor is greater than a specific gravity of the fuel and less than a specific gravity of water.
