General
The Fumex FB fan is a radial fan for the evacuaon of
gases, smoke and low weight parcles. The fan series
conforms to the protecon and safety regulaons in
the EU's Machinery Direcve. The fans boast high
levels of quality and operaonal reliability. ALL fans
undergo inspecon and test operaon before leaving
the factory. However, risks can arise with any fan if:
- it is not installed, used or maintained by trained
personnel.
- it is not used in the intended manner.
Please note that electronic equipment is always
suscepble to stac electricity, high humidity,
high temperatures and line failures. The
equipment is supplied with high voltage. Use the
isolang switch when carrying out service work
on the fan.
The fans are not intended for use in the
evacuaon of explosive gases.
Fan installaon
Installaon may only be performed by authorised
personnel with regard to these installaon
instrucons and applicable regulaons. Make sure
that all safety-related fan components sasfy their
funcon. The stability of the fan must always be
ensured during operaon. In order to achieve
opmum funcon, it is important for the fan's duct
connecons to be correctly executed. Incorrect
installaon can cause considerable deterioraon in
the fan's performance with regard to pressure drop
and sound levels.
In order to achieve opmum performance, we
recommend that the inlet connecon is a straight
duct that is 5 mes the diameter of the duct. If an
outlet duct is used, the same applies to this. If the
system requires a 90° bend in the outlet, it should
deviate in the impeller's direcon of rotaon (see
below).
There is always a risk of clothes or loose items
being sucked into a free-blowing fan. This can
cause personal injury or damage to property.
The fan is supplied with the outlet poinng as
illustrated on page 1. If an alternave outlet air
direcon is required, the fan housing can be set in 8
possible posions. If the direcon of outlet is changed,
thread locking must be applied to the screws. Take
great care to ensure that the impeller is not damaged
when reinstalling the fan housing.
In the event of outdoor installaon, a drainage hole
must be drilled at what becomes the lowest point in
the installed fan, according to the selected outlet
direcon.
In the case of professional installaon, too, fans
can produce harmful noise levels. It should also
be noted that specified noise data (see separate
product sheet) can be altered by the surroundings
or resonance in the operang locaon.
The fans are designed for installaon in systems
and therefore have no guard on the inlet. This
means that the fan must not be started unl it is
connected to a duct. The guard installed on the
outlet can be removed if you want to connect an
outlet duct (see accessories on page 8).
Maintenance
Fumex fans have been designed for connuous use for
an extended me with a high level of reliability. Like all
machines, regular servicing and maintenance are
required to achieve opmum funcon.
Fumex recommends the following maintenance
schedule:
Component Interval 6 months
Motor Check funcon. Replace motor if
necessary.
Impeller Check for any damage and clear
away foreign objects if necessary.
Replace impeller in the event of
damage.
Fan housing Check that connecons are secure
and clear away foreign objects.
Check the drainage hole and clear
if necessary.
