A filter device is for the filtration of gases contaminated with particles, such as welding gases, in particular produced in manufacturing processes using 3D printers in a production room (). The filter device has a filter circuit having at least one filter element (), which filters the particles from the gas. At least a part of those particles get from this filter element () into an assignable receptacle (). The particles within a back-flushing process get into the respective receptacle (). At least one further filter circuit has at least one further filter element (NF, NFthat filters a fluid having the particles obtained at the back-flushing process.

Filter device for the filtration of gases contaminated with particles

A filter device for transmission oil has a filter element () insertable into a transmission oil pan () with a filter medium () separating an unfiltered side from a filtrate chamber connected to an outlet (), to which a suction oil pump can be connected. The filter medium () has a first structural layer () having a predetermined surface area and predeterminable filter properties and has a second structural layer () having predeterminable filter properties. The surface area of the second structural layer () is different from the surface area of the first structural layer (). The structural layers () encompass an inner filter cavity () and are pleated having the same type of pleats. The pleated structural layers () extend in axial alignment between two end caps () of the filter element (). Viewed in the flow direction of the fluid flow to be cleaned, the structural layers () having the higher filtration grade are downstream of an upstream structural layer () having a lower filtration grade.
