Arrangement of the filter elements
In most cases, filter elements will be vertically arranged. After being deflected in the preliminary extraction chamber of the filter system, the air flow impinges upon the filter elements from below and passes upward through the elements.
In special cases, the use of horizontally arranged filter elements is effective. The uniflow principle is used here: air and dust flow in the same direction, from the bottom upward. The horizontal configuration means that this system concept can highly effectively separate especially light and fine types of dust, with effective air-pulse filter cleaning. This prevents fine-dust concentration in the filter chamber. The dust is moved through the descending untreated-air flow into the dust-removal area.
