Abstract
An adapter frame for mounting onto a base, in particular a suction device, a system box and/or a roller board, and for receiving a particle collecting container for a cyclone pre-separator, where the adapter frame includes a rectangular underside and adapter frame peripheral walls extending upwards from the underside, and lower adapter frame couplers, designed to provide a releasable, vertically tension-proof coupling to the base when the adapter frame is positioned on the base. The adapter frame on its upper side has a container receptacle for receiving the particle collecting container, the horizontal inner contour of which tapers towards the underside, so that the container receptacle is able to receive and horizontally stabilise a particle collecting container having an outer contour tapering downwards.
