Intended use includes the following:
• With individual versions, a space heater is possible
EN
(only category Ex db eb II 2GD T4 135 °C).
• Equipment categories 2G and 3G:
The fl ow medium and the area surrounding the blower
do not contain substances that may corrode the materials,
such as acids, alkaline or caustic solutions, solvents,
airborne rust, iron oxides, aggressive or abrasive gases,
liquids or solid substances. The fl ow medium is free from
substances which may settle, are adhesive or may form
condensates, and is free from foreign particles.
• Equipment categories 3D:
The fl ow medium and area surrounding the blower do not
contain a substances that may corrode the materials, such
as acids, alkaline or caustic solutions, solvents, airborne
rust, iron oxides, aggressive or abrasive gases of liquids.
The fl ow medium is free from substances that are
adhesive or may form condensates.
• Blowers with motors according to type of ignition protec-
tion Ex eb are suitable exclusively for mains operation
with rated voltage ± 5% and frequency and must never be
used for frequency-converter operation.
• Fans with motors in accordance with ignition protection
type Ex db eb are only suitable for frequency converter
operation with a rated voltage of ± 5%.
• The values for the maximum/minimum frequency can be
found at 3.3.1.
Operation in a prohibited area
Danger!
Risk of destroying the fan!
Operation of the fan in the hatched area (1) trig-
gers pumping eff ects and results in strong vibra-
tions.
This results in the fan being destroyed. Operation
of the fan is only permitted from the minimum
volumetric fl ow rate.

Values for the minimum volumetric fl ow rate can be found at
page 24.
Designated use excludes the following:
• Special ambient conditions such as, for example, ambient
temperatures at the installation / operation site of more
than +40 °C; dust deposits; vibrations at the installation /
operation site of the blower.
• Operation near / in fl ames or hot gases. The blower must
not be used as an ignition or fl ame arrester.
• Conveying of foreign matter.
• Adiabatic compression and shock waves, lightning,
electromagnetic waves, ionising radiation, ultrasound.

Operating and assembly instructions RD ATEX
special equipment, the enclosed supplementary operating
and assembly instructions must be observed and adhered
to. The supplementary instructions diff er in certain respects
from these Operating and Assembly Instructions.
Elektror blowers off er a high level of operational reliability.
As the blowers are high-powered machines, the safety in-
structions must be strictly observed in order to avoid injuries,
damage to objects and to the machine itself.

1.3 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).

1.4 Electrical hazards

Danger!
Danger from electric current!
Live components carry current and cause fatal
injuries!
Deactivate the device before opening it, reaching
into it or inserting tools into it; check that compo-
nents are not live and secure it against reactiva-
tion.
1.5 Danger when reaching in and due to 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.
1.6 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.

1.7 Suction eff ect
Warning!
Risk of injury due to suction eff ect!
Objects, clothing and hair can be sucked in at the
intake port.
The operator is required to wear a hairnet and
tight-fi tting clothing.
Do not stay near the suction opening during
operation!
1.8 Blowing eff ect 2
Warning!
Risk of injury due to strong blow-out eff ect of the
medium and ejected parts!
Impurities, debris and impermissible media may
cause objects to be thrown out of the fan outlet at
high speed!
Make sure that the fan delivers only clean air!
