1.1 Designated use
The blowers are designed for delivering clean air only.
Use of the blowers for
• aggressive,
• abrasive,
• sticky,
• toxic,
• explosive or
• very wet
media is not permitted.
The maximum temperature of the medium to be conveyed
must not exceed -20°C to +80°C with the standard model.
The maximum ambient temperature must not exceed +40°C
or drop below -10°C.

Any solid matter or impurities in the medium to be conveyed
must be fi ltered out before they enter the blower. We recom-
mend a condensed water borehole at the lowest point in the
housing in the event of formation of condensation.
Series connection or parallel connection of fans is only pos-
sible after consultation with Elektror.
The blower is not suitable for installation outdoors. The blow-
er is fundamentally designed for S1 operation (continuous
operation).
However, a maximum of 30 switching operations per hour
are permitted.This model of blower is not designed for install-
ing or conveying in an explosive atmosphere.
Alterations and modifi cations to the blower are not permitted.
It is not permitted to dismantle the impeller without consulting
Elektror!
Elektror blowers are characterised by a high level of opera-
tional reliability. As the blowers are very powerful machines,
the following safety instructions should be strictly observed
to avoid personal injury as well as damage to property and
the machine itself.
1.2 Mechanical hazards
The mechanical hazards in Elektror blowers have been mini-
mised in accordance with the current state of the art, as well
as the requirements for safety and health protection. To elimi-
nate any further risk on the part of the operator, we recom-
mend that suitable protective gear be used and worn during
all lifecycle phases of the appliance (please refer to the in-
structions below).
1.3 Hazards arising from reaching in and unexpected
start-up
The rotating parts inside the appliance pose a high risk of
injury during operation. Before opening, reaching in or insert-
ing tools into the appliance, always shut it down and wait
until all moving parts come to a standstill. Make sure the ap-
pliance is reliably protected against restarting while work is
in progress.
Also make sure that no hazardous situation can occur as a
consequence of restarting after shutdown, e.g. as a result of
a power cut or blockage.
1.4 Weight and stability
Beware of falling hazards during transportation and installa-
tion in particular. Refer to 2.1 - Transportation and handling,
as well as 3.2 - Installation and assembly.
Warning!
The maximum speed stamped on the motor
V
rating plate must never be exceeded in order to
prevent personal injury.
The blower is at risk of mechanical damage if the
speed is exceeded.This can cause serious injury
or death!
Each component on the blower has unique natu-
ral frequencies. These can be induced by certain
blower speeds, which may result in resonance
mode. The blowers are designed in such a way
that resonance does not generally occur at a
constant operating speed. This may be induced
in certain circumstances when the speed is
changed if the blower is operated on a frequency
converter. These circumstances are also infl u-
enced by the customer's individual installation
situation or ventilation connection.
These natural frequencies must be excluded by
parametrising the frequency converter according-
ly should they be present within the speed range
of the blower.
