Abstract: A method for predicting a service life of a filter element of a filter module in a system, the filter element serving to clean air, includes the steps of: a) retrieving characterization data of the system from a database; b) retrieving characterization data of the filter element from a database; c) retrieving measurement data of the system detected in the system by sensor technology; d) retrieving measurement data of the filter element detected by the sensor technology in the filter module; e) retrieving measurement data of air to be cleaned; and f) creating a data model from the data and determining the service life of the filter element to be expected.

Abstract: A method for providing an air stream for a system, in particular a plant, includes the following steps: a. specifying an air requirement and a required degree of air purity of the system having the plant, and storing the values in a memory unit of a control module; b. cleaning the air stream in a filter module comprising filter elements; c. providing the air stream through the filter module to air inlets or air outlets of the system as a provided air stream; d. detecting a magnitude of the provided air stream and of an actual degree of air purity by a sensor system; e. comparing a magnitude of the provided air stream and of the actual degree of air purity to the stored values; and g. calculating a performance characteristic of the filter module. A volume of the provided air influences the performance characteristic.

Abstract: A filter element for adsorbing harmful gases from a fluid flow includes: a frame and a plurality of filter bodies arranged at a distance next to one another in the frame. A respective filter body has a plurality of openings. A respective filter body is connected to at least one other of the filter bodies via a respective contact element configured for electrical dissipation. The filter bodies are arranged in matrix form, the filter bodies are formed as honeycomb bodies, and/or the filter bodies comprise activated carbon.

Abstract: The invention relates to a filter element comprising a frame and bag-type filter pockets which are connected to said frame. The filter pockets have openings on the inflow side for the inlet of a fluid to be filtered into the interiors of said pockets, and the interiors taper in the direction of an outflow side. The aim of the invention is to provide an efficient filter element in which the fluid to be filtered is effectively cleaned, said filter element being characterized in that fluid conducting elements are arranged on the outflow side and/or on the inflow side of the filter pockets.
