Problems Associated with inadequate Ventilation |
| |
Stale or unpleasant odours, dampness and condensation
all contribute over time to the deterioration of a building
in a number of ways and thereby creating unpleasant, uncomfortable
and unhealthy environmental conditions.
Stale air is often caused by cooking smells drifting through
the building, dank atmospheres, smoking, or odours remaining
in a bathroom or toilet. Condensation usually occurs when moist
warm air comes into contact with a cooler surface, such as walls,
ceilings and windows. This often leads to the appearance of
mould growth or peeling wallpaper, or serious structural damage
developing such as timber decay developing.
These problems result from poor ventilation, but can be resolved
through the correct selection and application of fans, providing
better air quality and eliminating problems of dampness and
deterioration by eradicating condensation and unpleasant smells. |

Air flow to Australian Standards |
| |
All of the fans comply with Australian Standard
AS 1668.2 - 2002 for ventilation rates when used appropriately.
This standard requires the minimum flow rate to be no less then
90m3/hr (25L/s) for toilet, shower or bathroom area
with a single fixture, with the air flow rate increasing as
the number of fixtures and room size increases.
Air flow rates equal to or above the defined minimums will ensure
steam, odours and stale air will be exhausted quickly, enhancing
the environment for the occupants of the building.
