Rotor and, if any, seals. Check if the rotor is undamaged and free from particles that may clog the
matrix. If any, clean and remove dust and other foreign objects from the
rotor.
Check seals for any damages and any wear, replace if necessary.

8.3 WASHING THE ROTOR

reimpregnation after the treatment.
Washing the rotor is not a maintenance process but a method to restore the rotor's adsorption ability. This should only be carried out as last resort and in an extreme case if
