SCOPE OF APPLICATION  INTENDED USE
Vallox Exxeo roof fans are intended as fans for extract air ventilation
systems. The maximum temperature of air extracted by the roof fans is
+40°C. The structure of Vallox Exxeo roof fans is designed so that water is
led out without ending up in the duct system.
Vallox Exxeo roof fans may be mounted on top of a Vallox Exxeo roof
penetration part or a penetration made on site. When required, the
mounting frame included in the standard delivery can be used.
Vallox Exxeo roof fans come in seven dierent sizes 150...4100 (0.15...4.1
m/s, ps= 150 Pa)
Three dierent models are available for each size:
• Basic model, equipped with a control panel
- model marking, e.g. Vallox Exxeo 4100 (air volume 4,100 dm/s, ps =
150 Pa)
• DPC model, equipped with a control panel + pressure control
- model marking, e.g. Vallox Exxeo 4100 DPC (air volume 4,100 dm/s,
ps = 150 Pa)
• DS model, equipped with a dual speed converter. The model can
replace a 2-speed 3-phase AC roof fan. The control requires an existing
cable with 7 poles (2x3-phase supply + PE).
- model marking, e.g. Vallox Exxeo 4100 DS (air volume 4,100 dm/s,
ps = 150 Pa)
NOTE
If the roof fan is used
as an extract fan for
a kitchen/grease
duct, grease removal
prior to the fan must
be ensured as well
as not exceeding
the maximum
temperature of
extract air.

The following must be observed when choosing
the roof fan:
• The static pressure indicated by the graph = pressure available for
use in the ducts. The pressure was calculated at the bottom end of
the penetration part. Air density = 1.20 kg/m.
IMPORTANT
It is recommended
to keep the fan on at
all times, as water or
snow could enter the
structures. If the fan
is switched o, it is
recommended to use a
damper to protect the
duct system.

Vallox Exxeo roof fans may be installed on top of a penetration made on
site or by using the factory-made Vallox Exxeo roof penetration part. The
tilting part attached to the fan is equipped with a seal that seals the fan
against the roof penetration. The fan is fastened to the roof penetration
with self-drilling screws. Below is an illustration of the installation of the fan.
Where necessary, the mounting frame delivered with the fan can be
used for installing the fan on top of an existing flue or roof penetration
part.
Lift the fan from
the enclosure lugs.
Pay attention to the
lifting angle of the
sling. The lifting
angle of the slings
should be less than
50°.

The roof penetration part is made of magnesium-zinc coated sheet
metal. Inside, there is a galvanized perforated plate and a 60 mm
mineral wool plate covered with mesh-reinforced black aluminum
laminate. The fire rating of the mineral wool plate is (A2 - s1, d0) and
density 180 kg/m. It is intended for fire insulation of rectangular air
ducts up to fire rating EI60. The roof penetration part is delivered with
corner mounts which can be used for fastening the roof penetration
part to the roof structures. The roof penetration part includes a cable
trough through which the feed and control cables can be led to the fan.

K VALUES  AIR FLOW MEASUREMENT
Roof fans are equipped with measuring tubes. The pressure dierence
pm (Pa) measured from them can, together with the fan-specific k
factor, be used to determine the air flow qv (dm/s) of the roof fan. The
measuring tubes are in the vertical bracket behind the protective cover
of the fan’s control unit. A manometer can be connected to them. The
measuring tubes are marked with + and -. The k factors specified in
the table apply to air density 1.2 kg/m (+20°C). The air flow can be
calculated by using the following formula:
If the temperature of the air to be extracted deviates from +20 °C, the
air flow can be calculated by using the following formula:
air density in the
temperature of the air that
is to be extracted
r20 = 1.2 kg/m, rop =
qv(dm3/s) = k *√pm
rop
√r20
qv(dm3/s) = *k *√pm

SETUP
Before the starting the fan, ensure that the fan wheel can rotate freely
and that there are no loose or extra objects inside the duct system or
the roof fan. Switch the fan on briefly to check its stable operation. If
everything is OK, the roof fan can be started up.
An uninterrupted power supply to the roof fan (Vallox Exxeo
700–4100) is essential to ensure safe operation to the allowed
minimum temperature of the environment. If the motor does not start
although the power supply is working properly (no setting signal,
mains connection via the activation circuit), heating of the motor is
automatically switched on when the inside temperature of the control
unit goes down to -19°C, and when the temperature has risen to -15°C,
it is switched o again. Heating is implemented with a motor coil; the
power is standardised so that it is not sucient to run the motor (about
five revolutions per hour). In this way, freezing of the rotor can be
prevented.
SETUP
NOTE
There is a separate
instruction manual
for the control panel
of the Vallox Exxeo
basic and DPC
models.
NOTE
The control voltages
of the Vallox Exxeo
DS (dual speed
converter) model can
be adjusted, when
necessary, from the
potentiometers of
the roof fan control
panel (see the
internal electrical
connections of
the DS model) The
factory settings are 5
V and 10 V.

MAINTENANCE
In normal use, the roof fan does not require maintenance
in addition to the annual inspection and cleaning
described below:
• Checking the vibration and noise level
• Checking the condition and integrity of the fan
wheel blades.
• Overall visual check of the fan
• Checking the free rotation of the fan wheel
• Cleaning the fan wheel
• Cleaning the motor
• General cleaning (insulations, roof plate, etc.)
Replacing the fan
Switch o the voltage by using the safety switch and
wait at least five (5) minutes.
1. Undo the roof panel screws (8 screws) and
remove it.
2. Undo the service door screw and open the door.
3. Undo the screws of the rain cover (4) and remove
it.
4. Detach the fan cables from the fan motor
(models 700–4100). Detach the fan cables from
the control panel (models 150–300). Electrical
connections must be carried out by authorised
persons only.
5. Undo the bolts and screws (8) of the fan bracket
and lift o the fan assembly.
6. Undo the mounting screws of the fan and lift the
bracket o the fan.
7. Reassemble in reverse order.
MAINTENANCE
WARNING
The roof fan may endanger your life
because of the rotating parts and the risk
of electric shock. It contains capacitors
that take time to discharge after the
voltage is switched o. Before working
with the components, make sure that
there is no voltage. Wait at least five (5)
minutes to ensure that the voltage of the
capacitors is discharged to a safe level.
Do not make any changes or additions to
the product without Vallox’s permission.

Cleaning the fan wheel
Switch o the voltage by using the safety switch and
wait until the fan has stopped.
a. Undo the roof panel screws (8 screws) and remove
it.
b. Undo the screws of the rain cover (4) and remove it
(not absolutely necessary).
c. Lift and pull the side panels out.
d. Clean the fan wheel with a cloth and soapy water.
Take care not to detach the balancing elements.
The fan wheel can also be cleaned from below by
tilting the roof fan.
e. Reassemble in reverse order.
MAINTENANCE
IMPORTANT
The roof fan delivery does not include
protection against physical contact
installed at the suction outlet. Protection
against physical contact must be installed
if the roof fan is installed so that the fan
wheel can cause danger.
NOTE
If used for the removal of very dirty
exhaust air, the checking as well as the
cleaning of the fan wheel and motor must
be carried out more frequently.
Always follow local regulations on the
cleaning of ventilation equipment.
