Filter element, filter installation provided with such a filter element, and connecting plate and flange for use in such a filter installation

摘要

The invention relates to a filter element, comprising:
- two at least substantially cylindrical gas-permeable walls, wherein an outer wall extends concentrically at a distance round an inner wall such that the two walls define a space in which a filter material is arranged;
- an annular first closing member extending between the two walls close to a first end zone of the filter element for the purpose of closing the space close to the first end zone;
- a disc-like second closing member extending close to the second end zone of the filter element for the purpose of closing the filter element close to the second end zone; and
- coupling means for releasable coupling of the first end zone of the filter element to a connecting plate or flange such that in connected position the filter element connects concentrically to an opening in the connecting plate or flange, wherein:
- the two walls and the first closing member define a cavity close to the first end zone of the filter element for accommodating a seal; and
- during operation a first outer end of the outer wall is in direct contact with the connecting plate or flange.
