A low voltage fan can be installed in a wall and may be sufficient for small areas and don't require access to the sub ground. Another choice is to run the ducting instantly from the dampest part of the sub-ground area to the photo voltaic sub-flooring ventilator fan. A well carried out subfloor air flow system by Doctor Damp will remove stale moisture-laden air by using specifically designed pumps and subfloor followers to extract excessive moisture from the subfloor space. Our consultants and technicians are trained to design and set up subfloor ventilation techniques to take away floor moisture from beneath raised flooring.


Due to the usually decrease temperature under the home, this causes condensation and high moisture levels which over a interval could result in destruction of your subfloor area by way of mould, rot and termites.

Underfloor Ventilation
Hugely efficient, silently moves more air than any other sub-floor fan, matches 300 mm diameter flexible Sub Floor Air Vents duct.

Sub Floor Ventilation System

A higher quantity of air is blown into the sub floor area, which can, in consequence, force the damp, moist air out. The logic behind the exhaust system is that a larger quantity of stale air is sucked out of the sub floor house than the contemporary air that is blown into it. In order to achieve this, only one fan is devoted to the supply of contemporary air, whereas two are required for the expulsion of the stale air via vents.

Its major function is to enhance the airflow to areas the place a bunch of stale, damp air is cornered.


If the sub-ground ventilation is elevated substantially this could shrink the fungi as normally it thrives in moist humid circumstances. Another apparent signal of poor sub-flooring ventilation is a definite musty smell inside the dwelling.


Termites require high levels of moisture and damp subfloor areas are highly conducive to termite assault. Where very moist situations are current, termites can devote all of their energies to attacking timber rather than bringing moisture in. Increased moisture levels are additionally conducive to attack by borers (wood boring beetles).


No doubt you're acquainted with the expression the writing is on the wall if mould is present on the walls and ceilings this is indicator that poor sub-ground air flow is current. that the efficient way in getting the correct mix in sub-flooring ventilation is to combine using passive vents with fan-forced sub-floor ventilation methods.


This would usually be done through the lower a part of the wall. In order for cross move ventilation to be effective – air ought to really only be getting into from one aspect of the constructing and the sub flooring fan must be extracting from the opposite aspect.If/when cross circulate isn’t an choice (or not efficient sufficient e.g. because of pockets of non-shifting air) – the sub flooring fan could be ducted to one or more locations to extract moisture from central and/or particular damp areas.
