A filtration module is provided, the module including at least one filtration packet containing filtration media or one or more membranes, such as a stack of membranes, the at least one filtration packet having one or more fluid ports, the one or more fluid ports being surrounded by a primary seal and a secondary seal spaced from the primary seal. The secondary seals are designed to maintain sterility of the assembly during shipping, handling and/or installation. A removable film may cover one or more fluid ports to maintain sterility prior to use.

A filter device may include a filter housing and a filter element defining a longitudinal axis disposed in the filter housing. The filter element may be configured to be penetrated by a fluid flow in a radial direction from a raw end to a pure end of the filter element. A water separator may be disposed at the pure end of the filter element and arranged axially spaced from the same. The water separator may have a hydrophobic and annular diaphragm extending in an axial direction of the filter element configured to be penetrated by the fluid flow from a raw end of the water separator in a radially outward to a radially inward direction with respect to the longitudinal axis to separate water from the fluid flow.

A blood filtering device comprises a casing defining a containment volume and provided with at least a first inlet for the venous blood, at least a second inlet for the intracavitary blood, at least a third inlet for the extra cavitary blood and at least an outlet mouth for the blood; blood filtering means which are housed inside the containment volume and delimiting at least one filtering volume communicating with the blood inlets and at least one collecting volume communicating with the outlet mouth; where filtering means comprise: at least a first filtering element defining a closed profile and delimiting a first filtering volume communicating with the first inlet; at least a second filtering element defining a closed profile and delimiting a second filtering volume communicating with the second inlet; at least a third filtering element defining a closed profile and delimiting a third filtering volume communicating with the third inlet.

An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate is fixed with an outer enclosure. The mounting plate is further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve is fixed fluidly between the portions of the outer enclosure.

A disposable filter including an integrated sensor is provided for filtering a working fluid and monitoring the working fluid and/or the performance of the filter. The filter includes a housing with an inlet and an outlet with filter media disposed within the housing in a flow path defined between the inlet and the outlet. The integrated sensor is disposed within the housing, where the integrated sensor monitors a characteristic of the working fluid or other performance characteristic of the filter. The sensor assembly may include a communication module. The sensor assembly may include a RF tank circuit with a capacitor plate, which may be disposed adjacent a bypass structure that is disposed adjacent the outlet. Movement of a moveable part of the bypass structure in response to a pressure buildup will cause a shift in a resonant frequency of the tank circuit.

The disclosure pertains to a spin-on fluid treatment device, including a treatment medium disposed within a housing, a top surface having an internally threaded bore and an outlet tube at least partially disposed inside said threaded bore in a concentric position. The outlet tube can have an externally oriented sealing portion for engaging with a complementary element of an inlet spud of an entity that receives said treated fluids. The outlet tube can be configured as an alignment feature to guide the treatment device onto the inlet spud during installation. The outlet tube can be configured with both an externally oriented sealing portion and an alignment feature. The disclosure also pertains to a system comprising a machine having a treatment device head and a spin-on fluid treatment device, a kit, a spin-on fluid filter cartridge, and a method of mounting a spin-on filter cartridge onto a filter head.

A mobile oil filtration system includes a mobile oil reservoir having a plurality of wheels; a housing secured to the mobile oil reservoir; an input conduit secured to the housing; a pump in fluid communication with the input conduit; a spring-loaded filter downstream from and in fluid communication with the pump; a bag filter downstream from and in fluid communication with the spring-loaded filter; and an output conduit secured to the housing and in fluid communication with the bag filter.

A fuel pre-filtering element may comprise a casing provided with a fuel outlet, an internal tube, an upper annular element, a lower annular element, a filtering element and a cover. The filtering element may be arranged around the internal tube The upper and lower annular elements may be respectively fixed to the upper and lower ends of the filtering element The filtering element may be arranged inside the casing such that the internal tube establishes a contact with the fuel outlet, the upper annular element is arranged around the fuel outlet and in contact with an upper surface of the casing, and the upper annular element is deformed and forms an annular projection. The annular projection may establish a seal between the internal tube, the fuel outlet and the casing. The arrangement of the filtering element may be inside the casing and further form a region of unfiltered fuel.
