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.
