The in-line fan is installed within the subfloor; air conditioning type ducting is run to various points throughout the subfloor. The system is then balanced by adding baffles, so the air flow can be regulated evenly throughout the entire length of ducting, and damp stale air is sucked from all points within the subfloor.
The most powerful option is to use a centrifugal in-line fan which can be installed anywhere along the duction and connected to multiple areas. A typical fan has a capacity of 440m3/hr and uses 80W power. Significantly, it will move a large amount of air with ducting and multiple vents connected to it.

With this method we are in fact designing a one off system and every project – whilst following the basic principle of air extraction – is custom built.
With Moisture Cure’s help, this system can also be installed by the home owner or handy man, and we can offer complete installation of this system in most areas.
