	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.

	Steamy Environments
	Where steam is involved run-on timers are recommended to ensure the area is thoroughly purged. This will protect surface finishes as well as limiting the growth of mould.

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.

Energy Efficiency

The Building Code of Australia now incorporates Thermal Performance Requirements to facilitate the efficient use of energy in housing and commercial buildings. Fantech Plus offers fans and accessories to achieve compliance for Building Sealing, as well as improving electrical efficiency.

Paragraph 3.12.3.4 states: An exhaust fan must be fitted with a sealing device such as a self closing damper, filter** or the like when serving -
(a) a conditioned space; or
(b) a habitable room in climate zones 4, 6, 7 & 8

** An exhaust fan is considered to be adequately sealed if it is fitted with a filter
such as the type commonly used in kitchen range hoods.
