Quad fan sub-floor ventilation systems from Envirofan
In 2001 Envirofan developed the quad fan sub-floor ventilation
system from its tried and tested product from the 1970's which was of the Solarfan
sub-floor ventilation system range.
The Envirofan sub-floor ventilation system produces ten percent more airflow than
the Solarfan sub-floor ventilation system did, due to its improved impeller design.
The Envirofan sub-floor ventilation system currently does 5,500 litres of damp air
per minute at 27dba(decibels) which makes it the most quietest sub-floor ventilation
systems in the market place.
Consumer Benefits and Product Advantages
As mentioned previously Envirofan sub-floor ventilation system have a low decibel
rating. This is very important as you don't want unnecessary noise entering the
habitable living area from the sub-floor ventilation system. Single fan impeller
sub-floor ventilation units do have a higher decibel rating.
The Envirofan quad fan sub-floor ventilation system as the name implies has four
individual fan impellers. Does this make it four times more expensive to replace
all impellers? The answer is a resounding No! The impellers on the quad fan sub-floor
ventilation system is approximately the same price to replace as single fan units.
Most sub-floor ventilation systems usually have only a single impeller. Why is this
a disadvantage?
In the event that the single fan should stop working, the sub-floor ventilation
properties are totally lost, until such time that the ventilation system is totally
replaced or that the sub-floor ventilation unit is repaired. This would also apply to
in-line fan sub-floor ventilation systems. The Envirofan quad fan sub-floor ventilation
system is different in that If the same situation should occur and one fan ceases to
operate then the sub-floor ventilation properties would continue at seventy five
percent of its normal operating capacity.
Another feature of the Envirofan quad fan sub-floor ventilation system is that it
is low voltage (12volt). This would mean that the home owner can install it without
electrocuting him or herself. Secondly as a power point does not need to be installed
in the sub-floor area this would save on an electricians cost. From the 12volt power
supply the length of cable that can be run to the sub-floor ventilation system is
twenty metres so any internal power point can be utilised.
In this day and age we should be more environmentally conscious of how we as humans
impact on our own natural resources which is not endless. The Envirofan quad fan sub-floor
ventilation systems is a low voltage ventilation system which can operate also on solar
power so this is going to out perform what any 240volt system can do in the way of power
consumption.
A Unique Design
The Envirofan quad fan sub-floor ventilation system design accommodates an integral
louvred vent (white or brown colour) which is the size of two bricks high by one
brick wide. This was not left to chance as it exactly replaces a terra-cotta passive
vent which most homes already have. If a house does not have these then an approved
sub-floor ventilation installer should be used.
Because of this unique design the Envirofan sub-floor ventilation systems does not
require flexible ducting in ninety eight percent of cases. This is great news as it
keeps the sub-floor area free of obstructions and airflow can travel freely, which
is the objective.
Overall Benefits
The ventilation message has been resounding for years and the consumer is becoming more
aware of what inherent problems are associated with poor sub-floor ventilation. Damp
and humidity in the sub-floor area makes this kind of condition conducive to termites.
Fan-forced sub-floor ventilation systems remove humidity from the sub-floor area by
physically extracting this poor quality air.
Humidity can also impact on wooden sub-floor structures by raising their moisture
content level. This will make these structures expand. This will create cupping and
warping of floor boards, Timber joists may bow lifting off brick piers, this will make
a floor to bounce. Excessive moisture content in timber will decrease the longevity of
the material by the presence of dry-rot. Sub-floor ventilation systems will control
these issues.
The most important is if left unchecked the lack of sub-floor ventilation will affect
your health. If sub-floor ventilation is inadequate this will penetrate into the living
area by the damp reacting with organic material in the sub-floor area. This will let off
an odour which can be quite harmful to the respiratory tract. By taking steps to rectify
this, sub-floor ventilation systems will re-direct this odour away from the living area
to the outside. After a time this odour will diminish as the supply air replaces the
stagnant air in the sub-floor area.
Conclusion
There is more to it than meets the eye when it comes to sub-floor ventilation and the
type of sub-floor ventilation system used. Envirofans knowledge that stretches from the
Solarfan era until now has really got it together in the design particularly of their
quad fan sub-floor ventilation system. It really capitalises on simplicity of design,
ease of installation and quality. Their knowledge in sub-floor ventilation really has
stood the test of time from all others.
