摘要

Device comprises at least one foaming unit (1) and at least one feed line (2) for the substance, which opens out into the foaming unit, where a compressed air-driven membrane pump (3) is arranged in the course of the feed line. A storage container is provided for the foamed material. The membrane pump is associated with at least one multi-way valve. The separate compressed air lines extend from the multi-way valve to the working air chambers of the membrane pump. The multi-way valve is connected with at least one storage container (7), which is associated with the condition sensor.
