Abstract: A cassette filter including a plurality of filter media packs, a frame for receiving the filter media packs, and protective grids. Two filter media packs in each case are arranged in a v-shape, and a gas flows through the filter media packs from a dirty gas side of the filter to a clean gas side of the filter in order to clean the gas. A respective protective grid of the protective grids is arranged on each filter media pack on the clean gas side. The protective grids have a grid structure with substantially closed curves of different sizes arranged centrically around at least one centre of the protective grid and with a plurality of connectors, which are oriented radially with respect to the centre of the protective grid and connect the closed curves to one another.

The frame is formed by four elements which are each configured in one piece: an inflow-side upper plate, an outflow-side base plate and two side plates.

Abstract: A filter module for filtering a fluid flow includes: a plurality of filter elements arranged parallel to one another in a fluid channel. A sensor is mounted on each filter element of the plurality of filter elements, each sensor being determining a loading state of a corresponding filter element. Each of the plurality of filter elements is a filter cartridge including plated filter medium. Each sensor is a flow sensor.

Abstract: A cassette filter for cleaning a fluid includes: a frame; and a plurality of filter elements having a filter medium provided with a folding. The plurality of filter elements are accommodated in a frame such that at least two adjoining filter elements of the plurality of filter elements are arranged at an acute angle to one another and form a V-shaped arrangement. Each of the plurality of filter elements has folded edges which are formed by fold peaks and fold valleys and extend perpendicularly to legs of the acute angle. Each filter element of the plurality of filter elements is provided with foldings such that a height of the respective filter element is smaller at all edge regions than a height in a central region of the respective filter element, and smaller folding surfaces than the central region result at the edge regions.

Abstract: A filter cartridge has a filter medium that is provided at least on an end face with a flange that serves for the installation of the filter cartridge in a filter arrangement, whereby the flange has a radial flange and a support section, whereby the support section extends in the lengthwise direction of the filter cartridge.

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 filter element includes a folded filter medium. The filter medium includes two longitudinal edges and transverse edges, and a first fold. The first fold is a zigzag-shaped parallel fold in such a way that folded edges of a first type extend parallel to the transverse edges of the filter medium and folded sections of a first type are formed between fold peaks and fold troughs. The filter medium is provided with at least one second fold as a counter-fold. A folded edge of a second type is present in each folded section of a first type. Each folded edge of a second type is oriented at an obtuse angle to the folded edge of a first type in the fold trough such that triangular folded sections of a second type are formed.

Abstract: A filter for purifying air includes a frame, layers of a filter medium, and separator plates. The layers of the filter medium and the separator plates are arranged in the frame. The layers of the filter medium are aligned at a distance from each other and one of the separator plates is arranged between each two layers of the filter medium. The separator plates are folded and are provided with folding in such a way that the separator plate is designed with a number of fold peaks and fold valleys on its first side and a multiple number of fold peaks and fold valleys on its other, second side. The fold peaks and fold valleys extend from the first side to the second side. The folding, as viewed in the flow direction, causes a trapezoidal cross-section of a respective separator plate.
