Eaton DWFA 4505 Duplex Filter

DWFA (ASME Design)

Eaton´s Pressure filter change over series DWFA have a working pressure up to 232 psi (16 bar). Pressure peaks can be absorbed with a sufficient safety margin. A three-way-change-over valve which is integrated in the middle of the housing makes it possible to switch from the dirty filter-side to the clean filter-side without interrupting operation.
