A filter cartridge for a filter apparatus, including: a filter element that encloses an clean space within the filter element, at least partially; wherein the filter element has an outflow opening in flow communication with the clean space in the filter element; wherein the filter element has a longitudinal axis extending through the filter element and through the outflow opening; wherein a hollow base for connecting to a housing-side fastening element is arranged on or in the clean space; wherein an interior of the hollow base is sealed off from the clean space in a flow-tight manner.

Filter cartridge for a filter apparatus

A filter insert for a filter device, having a filter element arranged on a longitudinal axis extending there through and a front-side flow opening arranged on the front side of the filter element with the longitudinal axis extending through the flow opening. The filter element has, with respect to the longitudinal axis, at least one flattened portion with a reduced radial extension or a through hole along the periphery of the flow opening the shortest interior distance in the filter element immediately adjacent to the front-side flow opening is shorter than the inside diameter of the front-side flow opening.

Filter insert for a filter device

A humidifier has a stack unit having a plurality of water-vapor-permeable membranes which are arranged parallel one above the other and spaced apart from one another. The membranes are enclosed at the edges at least in sections by an enclosing part, wherein the enclosing parts of membranes lying one above the other are directly connected to one another in a flow-tight manner.

Humidifier, in particular for a fuel cell

A humidifier has a stack unit having a plurality of water-vapor-permeable membranes which are arranged parallel one above the other and spaced apart from one another. Two adjacent membranes are connected to one another via fixing elements, wherein a first fixing element acts on the top membrane from above and a second fixing element acts on the bottom membrane from below.

Air filter

Disclosed are an air filter element, a filter housing, and an air filter in which the air filter elements have a high filtering capacity and a long service life by increasing the filter surface of an air filter element taking into account structural requirements for the air filter housing.

Air filter element and air filter

A filter device comprises a filter element that is comprised of at least two radially nested filter bellows, wherein at least one filter bellows is to be flown through in the radial direction and a flow space for the fluid is formed between the filter bellows. Each filter bellows is embodied as a star-shaped filter with filter folds arranged in a star shape. On at least one end face of the filter element a sealing ring is arranged between a filter bellows and the filter housing.

Filter device, especially an air filter

A filter element () for an air filter () has a tubular filter medium (), the annular cross-section of which encloses an interior () of the filter element and which has an inner wall () that adjoins the interior of the filter element and that extends in the form of at least one convex arch () and at least two concave arches (), the concave arch () being located between two convex arches () such that the interior () of the filter element has a constriction () in the area of the concave arch (), the constriction () being adjoined by two wide zones () of the interior of the filter element.

Air filter element, air filter housing and air filter system

A filter insert has a filter element with an end surface at an inlet side and an end surface at an outlet side that are spaced from one another in a main flow direction of the filter insert. A frame circumferentially extends about lateral sides of the filter element. An axial seal is supported on the frame and has a sealing direction in or opposite to the main flow direction. When inserted into a filter housing and contacting a sealing surface of the filter housing, the seal separates seal-tightly the inlet and outlet. The frame has on two opposite lateral sides of the filter element contact surfaces for clamping the filter insert by matching clamping elements. The contact surfaces are oriented opposite to the sealing direction and each have an individual profile of varying height extending along the two opposite lateral sides.

Filter insert and filter device

A filter device comprises a filter element in a filter housing, wherein the filter housing is to be closed by a cover element. A friction section of the cover element, in an intermediate position between closed and open positions, is in friction contact with a friction member while in the closed position of the cover element the friction section is without friction contact with the friction member.

Filtering device, in particular air filter

An air filter system () includes a filter housing () with a filter element () received within the housing. A secondary housing is secured to and closing the filter housing. The secondary housing includes a locking element operable to engage the filter housing and the filter element. The filter element () includes at least one fastening element () wherein the locking element () of the secondary housing () engages the at least one fastening element () in such a way, when the filter element () is accommodated in the filter housing () and is disposed between the filter housing () and the secondary housing (), that the secondary housing () is detachably clamped to the filter housing ().

Air filter system and filter element

A cyclone separator (') including a first cyclone component (&#x2032;) having at least one substantially cylindrical cell pipe () including a guide device (), a particle outlet () for separated particles, and a second cyclone component (&#x2032;) including at least one immersion pipe (). The immersion pipe () is received in the cell pipe (), at the outflow side end and is connected at least partially to the outflow side end of the cell pipe () and includes a central outlet () for the purified gas stream.

Cyclone separator

A two stage filter device includes a cyclonic pre-separator () designed as a pre-filter that separates the particles from the gas flow and a main filter element () arranged downstream as a second stage operable to filter by guiding the particles through at least one filter medium (). The main filter element () is received in a filter housing (). The main filter element () includes at least one retaining element () for stabilizing the position of the main filter element () in the housing ().
