9-3. Cleaning Filter Element

Clean the filter element with light oil (kerosine, gas oil, etc.) in the
following manner.

(1) Shake the filter element in four directions in the cleaning oil.
(2) Brush the filter element carefully to remove sludge.
(3) Blow off residual accumulations with an air spray.
(4) Rinse the filter element well and dry with an air spray.

《 Note》

The above way of cleaning is effective for wire gauze filter elements up to 40
microns in mesh size. In the case of wire gauze filter elements below 25 microns,

remove surface accumulations mostly by the above method and clean completely by

ultrasonic cleaning without fail.

In the cleaning tank, place the top and bottom of the filter element on the
vibrator side alternately and clean. While it depends on the capacity of the

ultrasonic cleaning equipment and the amount of sludge on the element,
the cleaning time should be at least 1 hour.
