Abstract
Embodiments for a fuel filter are provided. In one example, a diesel fuel filter comprises a header having an inlet port, an outlet port, a recirculation inlet port, and a recirculation outlet port; and a filter body made having different material than the header, the filter body coupled with the header and housing a filter membrane. In this way, electrostatic discharge may be reduced.
Claims19
A diesel fuel filter comprising:
- a header having an inlet port, an outlet port, a recirculation inlet port, and a recirculation outlet port;
- and
- a filter body comprised of a different material than a material of the header, the filter body coupled with the header and housing a filter membrane, the header comprised of a first plastic composition and the filter body comprised of a second plastic composition, the first and second plastic compositions being thermoplastic formulations having a same base thermoplastic and different carbon concentrations, the first plastic composition having a higher concentration of carbon than the second plastic composition and the first plastic composition and the second plastic composition including the base thermoplastic and a carbon additive.
A diesel fuel filter comprising:
- a header comprised of a material including a base thermoplastic and a first carbon concentration of a carbon additive and having an inlet port, an outlet port, a recirculation inlet port, and a recirculation outlet port;
- and
- a filter body comprised of a material including the base thermoplastic and a second carbon concentration of the carbon additive, the filter body hermetically coupled with the header and configured to house a filter membrane and to receive fluid from one or more of the inlet port and the recirculation inlet port and to transfer fluid to one or more of the outlet port and the recirculation outlet port, the first carbon concentration providing greater electrostatic discharge (ESD) characteristics than the second carbon concentration provides, and wherein a bottom surface of the header is in face-sharing contact with a top surface of the filter body.
A diesel fuel filter comprising:
- a header comprised of a first material having first electric discharge characteristics and having an inlet port, an outlet port, a recirculation inlet port, and a recirculation outlet port;
- and
- a filter body comprised of a second material having second electric discharge characteristics less effective at discharging an electric charge than the first electric discharge characteristics, the filter body hermetically coupled with the header and configured to house a filter membrane and to receive fluid from the inlet port and the recirculation inlet port and to transport fluid to the outlet port and to the recirculation outlet port, wherein the first material is a first plastic composition including a base thermoplastic and a carbon additive, the first plastic composition having a first concentration of carbon and the second material is a second plastic composition including the base thermoplastic and having a second concentration of carbon.
