ABSTRACT:
A device and a process are used for filling a column with a filler material. The column is provided on two ends with a fill opening or with an intake opening. The column is held by a holding device. Using the holding device the column can be inserted in a tank in which the filler material is located. The column is connected via a connecting line to a negative pressure source. By producing a negative pressure in the interior of the column the filler material can be sucked homogeneously into the interior of the column.
