A blood filtering device has a filtration section with filter medium separating raw side and clean side. A first communication path connects raw side and a first variable blood reservoir volume; a second communication path connects raw side and a second variable blood reservoir volume coupled to a receptacle. When varying the first variable blood reservoir volume, blood contained therein flows through first communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through second communication path into the second variable blood reservoir volume. When varying the second variable blood reservoir volume, blood contained therein flows through second communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through first communication path into first variable blood reservoir volume.

Blood filtering device

A whole blood hollow fiber membrane filter medium is provided with a ceramic material having pores of a pore size that ensures permeability to blood plasma or serum and its molecular components while blood cells are retained. The whole blood hollow fiber membrane filter medium is used for separating blood plasma from whole blood, wherein the blood plasma preferably shows no hemolysis.

A blood filtering device has a tubular housing with a tubular section and tubular housing volume. A filtration section with a filter medium separating a raw side from a clean side is arranged in the tubular housing. The filtration section is movable along the tubular section and movably sealed relative to the tubular housing. The filtration section separates the tubular housing volume into variable first and second tubular housing volumes. A first communication path extends between raw side and first tubular housing volume. A second communication path exits between raw side and second tubular housing volume. When moving the filtration section, blood in the first tubular housing volume flows through the first communication path to the raw side; blood plasma passes through the filter medium to the clean side; residual blood flows through the second communication path into the variable second tubular housing volume.

The invention relates to an air filter element, particularly for a passenger compartment for the driver's cab of agricultural and work machines, in particular with spraying and atomizing devices for pesticides and fertilizers, having an adsorption filter layer with activated carbon, a fine filter layer in particular for separating aerosols and a circumferential sealing for separating the raw side from the clean side during installation into a filter housing.

A compact filter element with a large filter surface area having inner and outer rings of filter material with an annular space between them, such that fluid to be filtered can be introduced into the annular space between the rings of filter material and a portion thereof can flow through the outer ring of filter material to the periphery of the filter element and another portion thereof can flow through the inner ring of filter material to the center of the filter element; at least one fluid-permeable support member for the filter material, and at least one end disk on an axial end face of the filter element affixed to the rings of filter material in a sealed manner, in which the end disk has a centrally arranged inlet opening for the fluid to be filtered and one or more radially extending distributor channels leading from the central inlet opening to at least one eccentrically arranged outlet opening which opens into the annular space between the rings of filter material to admit fluid to be filtered to the annular space.

Fluid filter element

An oil filter for an internal combustion engine with a cup-shaped housing that is releasably connectable to a receiving head. The housing has a first interlocking element that extends across at least a portion of the outer circumference of the housing and is interrupted by at least one axially extending recess. The filter element has a liquid-tight canister provided on its outer surface with second interlocking elements, which fit into the recesses of corresponding first interlocking elements when the filter element is installed in the housing.

Liquid filter system

A filter has a filter housing and a receptacle chamber in the filter housing into which a filter element is insertable. The filter housing has a housing cover for opening and closing an opening of the receptacle chamber. The housing cover is situated in an area of the filter housing between the oncoming flow side and the outgoing flow side of the filter element.
