ABSTRACT:
In cleaning plate-type filter elements in a tank filter, the tank is opened and a cleaning tube is placed upwardly around one of the downwardly extending filter elements providing an annular flow space along the length of the element. A seal member is located in the upper end of the cleaning tube to close off the upper end of the annular flow space. Pressurized cleaning fluid is supplied into the lower end of the tube where it flows upwardly through the annular space and then into the filter element to dislodge any contamination. The material displaced continues its flow through the filter element in the same direction as is taken by the fluid being filtered.
