4.2 Description
The multistage radial blowers F-CEV-S and F-CEV-D work according to the dynamic compressing principle
utilising non contact rotating impellors and are maintenance-free.
Model F-CEV-S is equipped with a vacuum connection (Fig. 2/A) and the F-CEV-D (Fig. 2/B) with a pressure
connection). The motor and blower form a very compact unit. A shaft seal is fi tted between the bearing and
pumping chamber. The impellors are fi xed onto an extended vertical motorshaft.
All F-CEV-D can be equipped with a solenoid valve (Fig. 2/X).
The F-CEV 3718-S3 (08) is equipped with a motor starter by default.
4.3
Areas of application
Model F-CEV-S can be operated as vacuum pump and F-CEV-D as compressor.
They have capacities upto 9,3 m
3
/min and obtain a pressure difference of up to 125 mbar. 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 701 (F-CEV-D) and D 702 (F-CEV-S).
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).
