Abstract
A fluid filter includes a vertical housing, a filter cartridge, and a bypass valve. The housing has a fluid inlet for communicating a fluid into the housing and a fluid outlet for communicating fluid downstream of the housing. The filter cartridge is disposed within the housing between the fluid inlet and the fluid outlet and includes a filter element for filtering the fluid, as well as means for maintaining and relieving a predetermined level of pressure across the filter element to provide an accurate visual indicator as to whether the filter element needs replacement. The bypass valve allows fluid to flow from an unfiltered side of the filter element to a filtered side of the filter element when the pressure across the filter element exceeds the predetermined pressure.
