Moisture extraction device and wall provided with such a moisture extraction device

摘要

The present invention relates to a moisture extraction device configured to extract moisture from a wall. The moisture extraction device comprises a tube, an inner wall and a central axis, in which tube a partition extends parallel to the central axis, with both long sides closely abutting against the inner wall of the tube. The moisture extraction device further comprises a closing device which is in contact with an end side of the partition and which partially closes the tube, defining a ventilation channel on either side of the partition, so that air can flow into the tube via one of the ventilation channels, into a first subchannel between the partition and the inner wall of the tube, to the other side of the partition into a second subchannel between a second surface of the partition remote from the first surface and the inner wall of the tube and out of the tube via the other ventilation channel. The tube has a circular cross-section.
