This fan is designed for easy cleaning and long life.
Keep this user guide handy. The fan has been set by the
installation engineer to suit your kitchen or bathroom
application. Your EnviroVent Filterless Extract Fan
has been designed to improve air quality and reduce
humidity levels in kitchens and bathrooms to help
resolve the condensation and mould problems which
can eect dwellings in winter.
HOW IT WORKS
The EnviroVent Filterless Extract Fan works in a
constant trickle mode to create background ventilation
to maintain a healthy environment.
Vapour tracking
As standard the unit is tted with vapour tracking
(except for 2 speed models, see below). The fan senses
the amount of moisture being created in the room
which causes the fan to increase in speed to match
the rising humidity and reduce in speed to match falling
humidity. This intelligent function reduces your energy
costs, wear and tear on the motor and ensures a long
quiet life.
Pullcord
All units are tted with a pullcord override for odour
control (if remote see below). In the event that you
wish to activate the fan to full power in conditions of
low humidity simply pull on the pullcord and the fan will
boost to maximum extraction rate.
OPTIONS
Remote control
Remote control override for odour control. In the
event that you wish to activate the fan to full power
in conditions of low humidity simply press the remote
control boost switch and the fan will boost to the
maximum extraction rate for 3 to 4 minutes before
returning to the trickle extract rate.
2 Speed Version
The unit is also available in a two speed conguration,
without vapour tracking. These units run at a constant
trickle or at boost speed as required by the user.
Remote Switch Wire
The unit is available with a remote switch wire. On these
units the boost switch may be located up to 3 meters
away from the unit.
ENERGY USE
The EnviroVent Filterless Extract Fan uses award-
winning Ultra Low Watt motor technology to give
the lowest running costs of any domestic extract
fan. It uses only a minimal amount of electricity
whilst eliminating stale and moist air from the home.
This gives an annual running cost of only £1.97
based on an electricity cost of £0.15 per unit (kWh)
and a two hour ‘boost’ per day. In addition, the
Filterless Extract Fan is guaranteed for 5 years and
has no maintenance requirement during this period
saving both time and money for the user.
