In vacuum impregnation process, the parts to be impregnated are put in the enclosure/tank and a vacuum is created to remove the air trapped inside. The varnish or impregnating fluid is than allowed to enter the tank, which reaches each and every pore/cavity creating a solid winding/product. The vanish and winding product can be heated before impregnation to release any air and/or moisture trapped inside. They may be heated in oven to dry the varnish/impregnated fluid. In case of wooden articles/boards, the solutions reach vary deep eliminating attacks by terminates etc. from within and also from outside.
