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.

Filter module comprising sensor and method for determining the state of a filter element

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.

Cassette filter having a filter element with special folding

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.

Filter cartridge and filter cartridge arrangement

A sensor has an electronic chip and a sensor chip which are arranged within a functional volume which is at the most 4-5 mm long, a maximum 2-3 mm wide, and with a maximum height of 0.5-0.8 mm, thereby provide a potentially economical filter element having a compact sensor.

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.

Cartridge filter for purifying gas

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.

Filter system

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.

Cassette filter

A cartridge filter includes a folded package including filter material and a frame holding the folded package. The frame includes a plurality of profiled strips having identical profiles, and each having two ends. The frame also includes a plurality of corner joints, each disposed at an end of a respective profiled strip. Each corner joint includes an end cap for engaging pair wise with an end cap of an adjacent one of the plurality of corner pieces.
