Abstract: A method for predicting a change of at least one state variable, which characterizes a service life and/or performance of at least one air filter, includes the following steps: detecting at least one value of at least one influencing variable, on which the change in the at least one state variable per unit of time depends; detecting a time period for which the influencing variable having this value acts on the at least one air filter as a time duration; supplying the at least one value of the at least one influencing variable to at least one model which supplies an output quantity that is a measure for a contribution made to the change in the at least one state variable per unit of time that is caused by the at least one influencing variable; and determining the change of the at least one state variable.

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 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 mobile purification device for purifying indoor air and/or fresh air, has a holder and a filter element having a particle-filtering and a gas-adsorbing region, the particle-filtering region having a filter medium and the filter element being received in the holder to purify indoor air and/or fresh air containing smoke and/or particles and is useful as a mobile purification device, filtering particle-polluted and/or smoke-polluted indoor air and/or fresh air as effectively as possible, with particulate, emitted contaminants being prevented as far as possible from being discharged from the gas-adsorbing region into a space, wherein the particle-filtering region faces a downstream side of the holder and in that the gas-adsorbing region faces an upstream side, which can be supplied with indoor air and/or fresh air polluted with smoke and/or particles.

Abstract: The present disclosure relates to a filter element that includes a frame and bag-type filter pockets which are connected to the frame. The filter pockets have an inflow side and an outflow side, wherein at least one opening is present on the inflow side for the inlet of a fluid to be filtered by the filter pockets. The interior of each of the filter pockets tapers in the direction of their respective outflow side. Fluid-guiding elements are provided on the inflow and/or the outflow side of the filter pockets. An efficient filter element in which the fluid to be filtered is effectively cleaned is therefore provided.

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.

Abstract: The invention relates to a cartridge filter for purifying gases, said filter being especially embodied as a filter for fine or suspended matter. The inventive filter comprises a frame into which at least one folded package which consists of a filter material through which gas flows is introduced. The end pieces of the strips of frames are interconnected by corner connectors. said frame strips (1) consists of at least two individual elements (2,3) which are oriented perpendicularly to the direction of flow, engage with each other in a positively locking manner, and/ or can be interconnected.

Abstract: A filter system includes several filters, particularly a main filter and at least one prefilter, which are disposed one after another and are made of a filter material that is encompassed by frames. The sides of the frame of the main filter and the frame/s of the prefilter/s, which face each other, include connecting elements. The individual filters can be coupled to each other in a form-fitting manner.

Abstract: A cassette filter comprising a frame and a pleated filter material that is inserted therein, in addition to a protective grid having passage holes. The protective grid is fastened at a distance from the filter material in the frame and has a flow resistance that is smaller than that of the pleated filter material. The protective grid includes at least one film strip that is bent around the passage holes, said film strip extending parallel relative to the direction of flow of the medium to be filtered, and in that the protective grid recurrently contacts at least one other identically bent film strip outside the passage holes in contact points and is glued to said other film strip in the contact points.
