The device comprises a tube (1) with perforations (2) arranged in a blind hole (4) cut in a wall and supporting an inner concentric tube (7) with a solid wall. The space (9) between the two tubes is used to blow a current of air through restricted at the inlet (11), undergoing a reduction in loading within the circuit thus generating a depression which pumps humidity from the wall (5) and expels the same through the centre (10) of the tube (7). The above may be adapted to any thickness of wall by the provision of extensions (12).

Why it's free to use
- Filed March 19, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 19, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 19, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
