Connection device for a suction apparatus of a vacuum diaphragm filter

Abstract

A connection mechanism for a suction device for vacuum membrane filtration applications, includes a support for receiving a membrane filter or a filtration base, a cavity formed below the membrane filter or the filtration base, a suction duct which opens centrally into the cavity, and a ventilation duct which opens laterally into the cavity. The connection mechanism further includes a closing element which can be moved into several switching positions and which can block or unblock both the suction duct and the ventilation duct depending on the switching positions.
