A filter element has a first filter layer that has an active carbon layer, a top cover layer connected to the active carbon layer and a bottom cover layer connected to the active carbon layer opposite the top cover layer, wherein the first filter layer is folded to a first bellows. At least one second filter layer having an active carbon layer, a top cover layer connected to the active carbon layer and a bottom cover layer connected to the active carbon layer opposite the top cover layer is provided. The at least one second filter layer is folded to a second bellows. The first and second bellows are folded identically. The at least one second filter layer is arranged on the first filter layer in a positive-locking way by fold alignment of the first and second bellows to form a composite of filter layers.

An apparatus for separating aerosols or particles from a gas stream composed of a flow housing through which the gas containing the components to be separated flows, a separator, which is arranged in the flow housing, and a corona electrode, which is provided upstream of the separator in the direction of flow. The corona electrode is located substantially outside the gas flow. An air volume stream from the corona electrode flows into to the gas flow to transport charge carriers generated by the corona electrode into a charging zone in the flow housing.

An arrangement monitors the useful properties of pressure fluids (,) in fluid-technical installations. A plurality of measured variables, each representing a useful property of the pressure fluid, are determined by a plurality of sensors (,) which are combined with a pump (,) to form a structural unit which can be build into a tank (,) containing the pressure fluid. The sensors (,) are hydraulically connected in series with the pump (,).
