After that, you can place the filter element under light pressure cleaning.

Remove the filter element from the bath and use compressed air to blow out the solvents.

In a matter of four to five hours, be sure that the element is clean enough.

Replace it and adjust all the joints properly.

In a simplex element, you can turn the system on and continue the filtration process.

In a duplex system, use the switch valve to divert flow of liquids and clean the other filter.

5.2 High Pressure Nozzle

This process will follow the same procedures of removing the filter element for the simplex and duplex system.

The difference will come in the cleaning process of the star pleated filter element.

In this case, you will use a high pressure nozzle to remove the contaminants.

The nozzle can emit a solvent most preferably water at high pressure or blow air at high pressure.

The solvent flowing at high pressure will dislodged the contaminants from the filter element.

It will also soak the adhering contaminants which will fall off easily in the second attempt.

After that, you will blow off the solvent from the filter element as a process of drying it up.

Replace the filter element and allow it the filtration process to continue.
