1.2. General
The VBP+C4 is a very-low-pressure assistance fan delivering pressure compatible with the design of passive stack
ventilation. It is intended to improve and optimize the draught of passive stack ventilation ducts and belongs to the category
of hybrid ventilation systems.
The VBP+C4 is available in 2 pre-configured versions:
ST version: Version pre-configured in ST mode, uncontrolled stand-alone, at constant speed adjustable on a built-in
potentiometer.
MS version: Version pre-configured in MS mode, controlled by a management system:
▪Management of the fans in groups (up to 5 groups of 5 VBP+),
▪Individual setting/adjustment of the speed of each fan according to the site configuration (number of
storeys, ductwork...)
▪Speed control of each fan according to the temperature, (item sold by Aereco), wind or by using a
clock (items not sold by Aereco)
▪Indication of operation of the system and alarm reporting.
This version requires the use of two specific types of modules.
The versions (ST and MS) are the same product with different pre-configurations. It is therefore easy to change from
one version to the other.
1.3. Main functions

3. INSTALLATION
3.1. Fitting on stack
The components necessary for adaptation to the emergences of the ducts vary from one site to another.
In the case of an individual duct, a horizontal platform, located at the level of the emergence of the duct, is necessary for
attachment and for airtightness with the fan. A plane plate of the right dimensions, attached to the top of the stack, is
sufficient.
For the grouping of ducts, an adaptation plenum compliant with the recommendations stated below is necessary to
ensure proper aeraulic operation of the whole (loss of head minimized) and for attachment and tightness with the fan(s).
General recommendations for the placement of adaptation components:
▪The adaptation components must be made of a material strong enough to bear the weight of
the fan(s).
▪The latter must be fastened to the stack securely and so as to assure a good seal with it; the
plenum as a whole must also be perfectly sealed.

3.2. Fixing of the fan control unit
It is strictly forbidden to drill the fan control unit.
The cable which links the fan to its control unit must be handled with care. It can not be modified of
lengthened
It is possible to fix the metal protection of the control unit either on a vertical face or on a horizontal face. In both cases the
control unit must be vertical with its cable glands facing downwards, to ensure an effective protection against the penetration
of water.
When installing the control unit on a horizontal face, it is necessary to maintain a distance between 50 mm and 550
mm between the fan housing and the metal protection of the control unit.
To make the VBP+ F400 compliant, every electrical cable linked to the control unit must be 400 °C resistant.

3.3. Case of an individual duct”
For a rectangular duct, the constraints are the following:
▪The top platform must be rectangular and measure at
least 600 x 600 mm.
▪The opening cross-section of the duct must not exceed
245 x 245 mm if it is desired to avoid reducing its cross-
section.
▪The fan must be centered on the duct.
For a circular duct, the constraints are the following:
▪The top platform must be rectangular and measure at
least 600 x 600 mm.
▪The opening cross-section of the duct must not exceed
Ø350 mm if it is desired to avoid reducing its cross-section.
▪The fan must be centered on the duct.
3.4. Case of ducts grouped under a single fan
For all grouped duct configurations, an adaptation plenum is necessary. The plenum must:
▪provide a top platform measuring at least 600 x 600 mm.
▪provide a circular outlet Ø350 mm centered on the stack
▪ensure a height of air of at least 180mm between the end of the stack and the outlet section Ø350 mm.
▪The fan must be centered on the outlet section Ø350 mm.
Example of a typical stack of the collective and individual type:

11/28
TF6751_D
Aereco S.A.
3.5. Case of ducts grouped under 2 fans
For all grouped duct configurations, an adaptation plenum is necessary.
▪The plenum, even if made in a single piece, must provide 2 distinct volumes, perfectly sealed from one
another.
▪For each of the 2 units, the plenum must provide a circular outlet Ø350 mm centered as closely as
possible on the grouped duct.
▪The plenum must ensure a height of air of at least 180 mm between the end of the stack and the
outlet sections Ø350 mm.
▪The fans must be centered on the outlets Ø350 mm.
▪Each 350 mm outlet must be at least 1,000 mm from the other and at least 500 mm from the bulkhead
separating the volumes.
The plenum must provide 2 virtual platforms measuring at least 800 x 600 mm each (see example below).
Example of grouping of 8 individual ducts:

Aereco S.A.
3.6. Limits
All the following cases must be avoided, because they would lead to non-compliance with European
EMC requirements or non-compliant aeraulic performance or deterioration of the equipment or of
the ventilation system.
▪It is forbidden to install more than 2 fans per stack.
▪The stacks (1 or 2 fans) must be at least 3 m apart (distance from the outer edge of the fan to
the outer edge of the nearest fan of the other stack)
Anticipation of maintenance and chimney sweeping constraints
To allow access to the ducts located under the fan (inspection, chimney sweeping) it may sometimes be necessary to
incorporate one or more of the following features:
▪Soot door. This is generally located on the side of the stack or of the plenum.
▪Top plate tipping system (with hinges and catches).
▪Attachment that can be removed from and refitted on the top plate.

3.7. Installing the fan
1) Ensure the proper adaptation of the fan on its stack (see section above).
The plate holding the outlet Ø350 mm can be designed with 3 crimped M8 nuts positioned as shown below
to allow the attachment of the fan.
2) Remove the fan from the pallet.
▪Use only the 2 handles located under the uprights to handle the fan.
▪Wear suitable gloves (some of the metal parts may be sharp)
▪Do not set the fan down on an obstacle that might damage the turbine.
▪Do not lay the fan flat (horizontally)

14/28

3) Loosen the 4 screws and take off the cap
4) Check the couplig alignment between motor axis and turbine axis. The coupling piece must fall down freely between both
axes without any friction until the thread turbine axis.

15/28
TF6751_D
Aereco S.A.
5) In case it does not fall down freely, loosen the 3 nuts (see below) and realign the motor plate so that the couplig falls down
freely from the motor axis to the turbine axis.
6) Gradually, tighten the 3 nuts with a torque wrench to 7.5 Nm. Tightening must be done one by one per occurrence.

16/28
TF6751_D
Aereco S.A.
7) Once the 3 nuts are tightened, check that the couplig is still able to fall down freely from the motor axis to the turbine axis
without any friction.
8) Tighten the coupling screw on the turbine shaft using the torque wrench to 4.6 Nm

11) Attach the fan to its specific adaptation using 3 x Ø 8 mm stainless steel screws + washers.
Note: The 2 handles can be removed by pinching them; this eliminates a potential source of noise due to mechanical
vibration.
12) Position the control unit at least 50 mm from the fan. Choose the side facing North to reduce the influence of direct
sunlight. It must be positioned so that the cable connecting the fan to it is not loose. If necessary, fit cable clamps.
- Loosen the M6 screw that are maintaining the support
plate to the fan’s body. Remove the magnet located on
the protective metal cover back.
▪- Fix the base of the metal protection using the screws
supplied either vertically or horizontally.
▪- Remove the magnet located behind the box metal
protective cover
▪- Loosen the 4 screws that are maitaining the protective
driver box to the plate support.
- Set the plate on the plenum
- Put back the support box horizontally or vertically by
tightening the 4 screws
