4.2 Description
The radial blowers F-RER and F-REL work according to the dynamic compressing principle utilising a non
contact rotating impellor. They are free of maintenance. They have a built-in motor. A high effi ciency impellor
is fi tted on to the motorshaft. A shaft seal is fi tted between the bearing and pumping chamber. The motor
fan cools both the motor and blower housing. Models F-RER rotate to the right, whilst the models F-REL
rotate to the left.
The models F-RER and F-REL can be delivered with different suction connections: Version (01) to (39) with
connection fl ange, version (40) to (69) with mesh fl ange and version (70) to (99) with pipe socket.
4.3 Areas of application
The models F-RER and F-REL can be operated as vacuum pumps or compressors.
They have capacities from 4.9 to 57 m
3
/min and obtain a pressure difference of up to 74 mbar on 50 cycle operation. The pressure and vacuum limits are indicated on the data plate (Fig. 2/N). The performance
curves showing capacity against vacuum or pressure can be seen in data sheets D 750, D 751, D 752 and
D 753 or D 760, D 761, D 762 and D 763.
The maximum permissible capacity for air depends upon the motor rating. This is indicated on the data
plate (N) and is shown in the data sheets for standard voltages and frequencies. The loading of each unit
depends on the specifi c gravity of the gas handled. Therefore when handling gases other than air there are
other pressure different limits to be considered. Please contact the supplier for further advice.
If the unit is switched on more frequently (at regular intervals of about 10 times per hour or at higher
ambient temperatures and intake temperatures, the
excess temperature limit of the motor winding and
the bearings may be exceeded.Please contact the
manufacturer should the unit be used under such
conditions.
If it is installed in the open air the unit must be protected from environmental infl uences, (e.g. by a protective roof).

5.4 Connecting the motor
DANGER
Danger of death if the electrical installation has
not been done professionally.
The electrical installation must only be done by a
qualifi ed electrician observing EN 60204. The operating company has to provide the main switch.
a) The motor‘s electrical data is given on the data
plate (Fig. 2/N) or on the motor data plate. The
motors comply with DIN EN 60034 and are in
protection class IP 55 and insulation class F. The
appropriate connection diagram is located in the
motor‘s terminal box (not for the plug connection version). The motor data must be compared
with the data of the existing mains network (current type, voltage, network frequency, permitted
current value).
b) Connect the motor via the plug connection or
a motor protection switch (for safety reasons a
motor protection switch is required and cable
fi tting must be provided to provide strain relief
for the connection cable). We recommend using
motor protection switches with delayed switch
off, depending on possible excess current.
Temporary excess current may occur when the
machine is started cold.
NOTICE
Power supply
The conditions at the installation location must
match the information on the motor data plate.
Without derating the following is permissible:

WARNING
Improper use
May lead to severe or fatal injuries. Therefore be
sure to obey the safety instructions.
CAUTION
Noise emission
The highest noise pressure levels measured as
per EN ISO 3744 are given in Section 9.
When spending a long time in the vicinity of the
running machine use ear protectors to avoid permanent damage to your hearing.
6.1.1 Checking the rotation direction
The intended direction of rotation of the drive
shaft is shown by the rotary direction arrow
(Fig. 2/O) on the motor cover (Fig. 2/h).
a) Start the motor briefl y (max. two seconds) to
check the direction of rotation. The direction of
rotation can be seen by looking through the slots
of the motor fan cover. When looking at the motor fan, it must rotate at F-RER clockwise and at
F-REL anti-clockwise.
NOTICE
Incorrect direction of rotation
Running in reverse for a long time may damage the
machine.
Use a phase sequence indicator to check the direction of rotation (F-RER ➝ anti-clockwise rotating
fi eld, F-REL ➝ clockwise rotating fi eld).

Commissioning and decommissioning
6.2 Adjusting the capacity of RER/REL
To avoid overloading the motor during starting
please take note of the following:
a) Do not start the radial blower unless it is connected on the pressure or suction side.
b) If the air requirement of the system is variable e.g. through valves, taps or variables inlet and/or outlet
orifi ces then these should be set so that maximum capacity is utilised. During start up this condition
will result in the highest motor load.
c) The full load current as indicated on the nameplate of the blower motor determines the maximum avail-
able capacity of the blower.
When starting up the blower please check:
I) Whether the voltage and the frequency correspond to the data on the data plate?
II) Whether at peak load the full load current is exceeded?
d) Exceeding the full load current indicates (if the voltage and frequency are correct) that the blower has
been overloaded with regard to capacity.
In such a case the power should be adjusted by throttling. Throttling can be achieved without changing
the base unit itself as follows:
d.1) Insert a ring shaped orifi ce plate made of aluminium or steel between the connection fl ange of the
blower and the pipe or at any place in the pipe. Its outside diameter and fi xing holes should conform
with the size of the fl ange. However its inside diameter should be smaller than the effective diameter of
the fl ange.
Adjust the internal diameter so that the amperage does not exceed the full load current.
Or:
d.2) Insert an adjustable valve i.e. ball or butterfl y between the connection fl ange of the blower and the pipe
or at any place in the pipe and adjust it so that the running amps do not exceed the full load current.
It is advisable to clamp the valve in this position so that the setting cannot be altered unless by authorised personnel.
The points d.1 and d.2 can be omitted if it is possible to reduce the power to the design value by re-
ducing the suction and/or exhaust diameter or by increasing the fl ow resistance within the system.
e) Instead of adjusting the system to the existing blower, it is possible depending on the model of blower
and on the rating of the motor to use the same size blower but with a larger motor. For further advice
please contact your Rietschle representative.

Maintenance and repair
7 Maintenance and repair
7.1 Ensuring operational safety
Regular maintenance work must be carried out in order to ensure operational safety.
Maintenance intervals also depend on the operational demands on the machine.
With any work observe the safety instructions described in Section 2.8 “Safety notes for installation, commissioning and maintenance”.
DANGER
Danger of death from touching live parts.
Before maintenance work disconnect the machine
by pressing the main switch or unplugging it and
ensure that it cannot be turned on again.
NOTICE
Capacitor
In case of capacitor failure (1 ~ drive) replace the
capacitor only with one that has identical rated
value.
The whole unit should always be kept in a clean condition.
7.2 Maintenance work
Interval Maintenance to be carried out Section
monthly Check the pipes and screws for leaks and to ensure they are
seated properly and if necessary seal again or tighten up.
monthly Check the terminal box and cable inlet holes for leaks and if
necessary re-seal.
monthly Clean the ventilation slots on the machine and the motor
cooling ribs.
depending on how dirty the
discharged medium is
