ABSTRACT:
A method for wetting a filter element by a high viscosity liquid and an apparatus for practicing such method are provided. In the method, a sealable container that is equipped with a vibration device and is capable of holding a pressurized liquid therein is used. The vibration device creates a vibration in the pressurized liquid such that trapped air bubbles in the filter element are separated from the filter element and are exhausted. The method and apparatus can be used for pre-wetting any filter element in any type of liquid, either of the high viscosity type or of the low viscosity type, even though it is particularly suitable for wetting a filter element by a high viscosity liquid and removing trapped air bubbles in the filter element.
