- This offers several advantages.
- the partial disassembly or assembly of the first filter assembly designed so much easier. All the more so, as the third filter 49 can be withdrawn through the exhaust air inlet opening 45 down and not only on the shaft opening 56th
- the pocket filter 53 may also be arranged separately from the other two filters 49 and 51 at a certain distance in the flow path.
- the present invention thus provides a particularly advantageous extractor hood, which is simple in construction, energy-saving and effective filter arrangements has, which are also in a very simple manner from the filter housing removable and replaceable.
