A conveying system including at least one tube connection, at least one dispatch station and at least one receiver station, where items are conveyed by an airflow in the direction of the airflow in the pipe connection from a dispatch station to a receiver station. The new feature of a conveying system is that the tube connection has an inner cross-sectional area, preferably a circular cross-sectional area, with a size greater than the largest cross-sectional area of an item, and which is preferably provided with at least twice the cross-sectional area compared with the largest cross-sectional area of an item. Hereby is achieved the advantage that several items may be conveyed in the same tube connection at the same time, where these items are sent individually and successively, corresponding to one item being sent immediately after another.
