Abstract
A filter element is provided with an ascending pipe and a filter material subject to soiling and is supported by a supporting pipe. The filter material is separable from the ascending pipe such that the multi-component ascending pipe can be reused and to reduce the weight of hazardous waste to be disposed of when the soiled filter material has been changed. The ascending pipe is provided at least on one of its ends with a reception for the filter material in such a manner that the filter material with the supporting pipe as one assembly (22) and with the ascending pipe (10) as another component are detachable coupled, allowing the exchange of the soiled filter material by new filter material while keeping the ascending pipe. The filter element can be assembled during production with less effort, thereby allowing for a reduction of costs.
