A Diesel Particulate Filter (DPF) assembly configured to be incorporated in the exhaust gas stream, the DPF assembly comprising: Quartz/Composite ceramic mixture disposed as filter elements, mechanical support components and optional electrical soot removal solutions including electrical, di-electrical and microwave solutions.

A filter matrix of nickel, nickel alloy, nickel-plated, nickel-oxide, nickel compound, or a combination thereof, surfaces, surface coatings, and impregnated surfaces that inhibit the growth of microbes that come in contact or in proximity to the surface of the filter. The nickel-based filter matrix reduces and/or eliminates microbes from air that flows over or through the filter. A fan or pressure differential can be used to blow or draw the fluid or air across the treated surfaces.

A filtered air supply assembly includes a filtration unit that can be worn on a user's clothing. The filtration unit including a plurality of filters each is integrated therein and each of the filters is filter air that is pumped by the filtration unit. A mask is provided that can be worn on the user's face. A mask air hose is fluidly coupled to the mask and the mask air hose receives air from the filtration unit thereby facilitating the user to breathe the filtered air when the mask is worn. A nose air hose can be fluidly coupled to the filtration unit thereby facilitating the user to breathe the filtered air when the nose air hose is positioned in the user's nose.

A filter for compressed air systems is provided. The filter includes a filter housing with a filter therein between an air inlet and an air outlet. Compressed air flowing between the air inlet and the air outlet passes through the filter housing and the filter element. A base is removably fastened to the filter housing which may be separated from the filter housing to allow the filter element to be removed and replaced.

The invention relates to a ceramic modular filter element comprising a first elongate hollow body, a second elongate body and a sleeve for coupling the first elongate body to the second elongate body, wherein the first elongate hollow body comprises a frustoconical section, the second elongate hollow body is configured to receive the frustoconical section of the first elongate hollow body and the sleeve comprises projections for engaging with a surface of the first elongate hollow body and/or the second elongate hollow body.

A separating device for separating a liquid from gas is provided with a separating element that has a housing with housing cover closing off an end face of the housing. A filter element is arranged in the housing. A coupling element is provided to couple the separating element to a connector device. The housing cover has a central first gas passage and a second gas passage arranged radially outwardly of the first gas passage. The housing cover has a housing cover thread correlated with the first gas passage. The housing cover thread is to be screwed to a coupling element thread of the coupling element. A fluid discharge channel is arranged within the coupling element for discharging separated liquid from the separating device. The housing cover thread and the coupling element thread, in a position of use of the separating device, are connected substantially seal-tightly to each other.
