Abstract

An operating and changing apparatus for a filter body located at a filter position that displays a filter body axis of symmetry located at a filter position and in which a particle filter is integrated in order to remove particles from a particle-laden fluid. The filter body has a fluid-permeable filter body opening and a fluid-impermeable filter body wall section. The apparatus has a housing that the fluid can flow through with a flow channel in which the filter body is so positioned that the fluid can flow through the particle filter. The flow channel has a flow inlet and a flow outlet such that the fluid flow between flow inlet and outlet runs through the particle filter of the filter body. The flow channel has a channel axis which runs parallel/collinear with the filter body's axis. The flow inlet and outlet are offset to each other, relative to the channel symmetric axis. The flow channel and the housing have a filter insertion opening and a filter disposal opening that are in alignment along the channel axis. A change of the particle filter takes place through exchange of the filter body with an exchange filter body with a replacement filter whereby the replacement filter bod…
