Patent number: 5885447Abstract: A filter arrangement for filtering fluid comprises a housing having an inlet and an outlet, a first cylindrical construction, a second cylindrical construction, and a bypass arrangement. The first construction includes filter media mounted within the housing. The first construction defines a first open filter interior. The first open filter interior includes a first dimension being a largest dimension across a cross-section of the first open filter interior. The second construction includes a filtration construction mounted within the housing. The second construction defines a second open filter interior. The second open filter interior includes a second dimension being a largest dimension across a cross-section of the second open filter interior. The second dimension is at least as large as the first dimension. The bypass arrangement has an open position and a closed position.Type: GrantFiled: July 3, 1997Date of Patent: March 23, 1999Assignee: Donaldson Company, Inc.Inventors: Jeffrey J.
