Abstract: A cabin air filter system for a vehicle, includes at least one particle filter element and a cyclone separator positioned upstream of the at least one particle filter element. The system includes a particle agglomeration device positioned upstream of the cyclone separator. A method for cleaning air to be supplied to a cabin of a vehicle, with the cabin air filter system.

Abstract: A cabin air filter system for a vehicle includes at least one particle filter element and an adsorption filter element that is spatially separated from the particle filter element and having at least one adsorbent honeycomb. The system further having at least one heating element adapted for heating the adsorption filter element for regeneration and a regeneration flap, wherein the regeneration flap is adapted to switch a regeneration outlet to the environment. The system is operable in a regeneration mode in that the heating element is activated so that the adsorption filter element is heatable to a temperature above a predefined regeneration temperature and the regeneration outlet is opened by the regeneration flap so that a regeneration air flow processed by the adsorption filter element is releasable to the environment. A method for cleaning air to be supplied to a cabin of a vehicle with the cabin air filter system.

Abstract: A mixing device includes a mixing container for receiving mixing material and a mixer cover, wherein a first seal and a second seal is provided between the mixing container and the mixer cover. The first seal and the second seal are so arranged that a first air space is formed between the first seal and the second seal.

Abstract: The present invention concerns a granular material conditioner for optimising grain sizes of granular materials comprising two discs which are rotatable relative to each other and which are arranged in substantially mutually parallel relationship, a granular material inlet through which granular material can be passed into the conditioner into an annular gap between the two discs, and a catch container for receiving the granular material which issues from the gap between the two discs by virtue of centrifugal force. According to the invention it is proposed that the catch container has an elastic curtain, wherein the curtain is spaced at least portion-wise from the catch container wall and limits the trajectory of the granular material issuing from the gap.
