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 cy-
cle 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 regu-
lar 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 pro-
tected from environmental infl uences, (e.g. by a pro-
tective roof).
