摘要： A round filter element for filtering gaseous fluid has a particle filter medium body and a separate noxious gas filter medium body arranged concentrically in relation to the particle filter medium body. The particle filter medium body and the noxious gas filter medium body surround an inwardly positioned flow chamber. A first common end plate flow-tightly covers a respective first end face of the particle filter medium body and of the noxious gas filter medium body. A second common end plate flow-tightly covers a respective second end face of the particle filter medium body and of the noxious gas filter medium body. The particle filter medium body is a filter bellows and the noxious gas filter medium body is a filter bellows. A filter device having a filter housing is provided with such a filter element.

摘要： A round filter element for filtering gaseous fluid has a particle filter medium body and a separate noxious gas filter medium body arranged concentrically to the particle filter medium body. Particle filter medium body and noxious gas filter medium body surround an inwardly positioned flow chamber. A first common end plate flow-tightly covers a respective first end face of particle filter medium body and noxious gas filter medium body. A second common end plate flow-tightly covers a respective second end face of particle filter medium body and noxious gas filter medium body. A gas-permeable support element is arranged at a wall of the particle filter medium body or of the noxious gas filter medium body. The gas-permeable support element projects into material of at least one of the first and second common end plates and is fixedly connected thereto. A filter device is provided with such a filter element.
