Publication number: 20150283486Abstract: An apparatus and method for filtering a liquid utilize a filter apparatus including a bypass filter, a full flow filter, and a flow balancing element for dividing a total inlet flow of fluid to the filter apparatus into a bypass portion, passing through the bypass filter, and a full flow portion, passing through the full flow filter. The bypass filter has a lower filtering efficiency than the full flow filter element, so that a venturi tube is not required for causing the bypass portion to pass through the bypass filter. The flow balancing element divides the flow into a desired bypass portion and a desired full flow portion, at a predetermined operating temperature. Below the operating temperature, the bypass portion increases and the full flow portion decreases, the bypass portion becoming greater that the full flow portion at a second predetermined temperature below the operating temperature.Type: ApplicationFiled: June 22, 2015Publication date: October 8, 2015Applicant: BALDWIN FILTERS, INC.Inventor: Greg Fisher

Publication number: 20150219049Abstract: A filter element is provided with a snorkel that facilitates bleeding of air along the outside periphery of a tubular filter media pack to a bleed chamber contained within the filter element. This may be employed in fuel filtration applications during installation and removal of filter elements whereby air can be temporarily trapped in a housing containing the filter element. The snorkel thus vents the air along the outside of the filter element and then into a bleed chamber where it can be communicated to a standpipe having an isolated bleed passage.Type: ApplicationFiled: April 14, 2015Publication date: August 6, 2015Applicant: BALDWIN FILTERS, INC.Inventors: Randy R. Allen, James N. Marshall

The filter element includes a ring of filter media with upper and lower end cap constructions attached to opposed ends of the ring of filter media. The upper end cap construction includes a base portion and an axial seal portion extending axially from the base portion. The lower end cap construction includes a support ring and a resilient portion.Type: GrantFiled: June 25, 2013Date of Patent: July 28, 2015Assignee: Baldwin Filters, Inc.Inventors: Kristopher W. Lepine, Jeffrey E. Rogers

Publication number: 20150182892Abstract: A filter assembly, a filter cartridge and method of filter fluid are provided. The filter assembly includes a filter base, a filter housing and a filter cartridge within the housing. The filter cartridge strips water from the dirty fluid flowing through the assembly. The filter cartridge defines a pair of fluid flow paths extending through a central cavity thereof. The fluid flow paths carry and keep separated a flow of cleaned fluid after it passes through filter media of the cartridge as well as the water that has been stripped from the dirty fluid flow.Type: ApplicationFiled: March 6, 2015Publication date: July 2, 2015Applicant: Baldwin Filters, Inc.Inventor: Stephen Schweitzer

Publication number: 20140346103Abstract: A filter base cap for sealing and protecting a filter base once a filter has been removed for storage, shipping and transporting of a mechanical system is provided. The filter base cap attaches to the filter base of the system to prevent leakage of residual fluid within the system, such as an engine or other device, after the system has been tested. The filter base cap will provide fluid circulation in the event the mechanical system is started prior to replacing filter base cap with a filter that would otherwise provide fluid flow to the mechanical system.Type: ApplicationFiled: May 14, 2014Publication date: November 27, 2014Applicant: Baldwin Filters, Inc.Inventors: Craig A. Worm, Steven J. Merritt
