To ensure safe operation of your KleeBlower compressor/vacuum pumps, please read
this instruction manual and pay particular attention to instructions marked with the
following signs:
DANGER
WARNING
CAUTION
1.1 Application
The KleeBlower is a complete unit ready for immediate installation either
as a vacuum pump or as a compressor. It is designed for handling air and
other non-flammable, non-corrosive and non-explosive gases only.
1.2 Vacuum and compression pressures
The drive motor can be loaded with total differential pressures given in the
technical data. Blowers with limited performance curves in the high
pressure range should be fitted with the relative pressure relief valves in
order to avoid an overload of the motor. Pressure relief valves can be
mounted directly on the outlet and the vacuum relief valves directly on the
inlet of the blower.
1.3 Temperatures
The permissible ambient temperature and gas temperature at the inlet is -
10 to +40 ºC. The maximum allowed humidity is 80%
Indicates an imminently hazardous situation
which, if not avoided, will result in death or
serious injury.

2 Operation
2.1 Transport and storage
When lifted by a crane, Kleeblower units must be secured at the eye bolt
on the pump casing.
Pay attention to the load-bearing capacity of the hoisting equipment. See
previous page for weight data.
The rolling contact bearings should be regreased or enclosed. They should
be replaced with new ones if more than four years have elapsed between
delivery and machine commissioning under favourable circumstances
(storage in a dry, dust free and vibration free room). Under unfavourable
circumstances, this period is considerably reduced.
2.2 Installation
A)
Kleeblower units can be installed in vertical, horizontal or slantwise
position. However take bearing load into consideration when installing the
blower: The following examples are for your reference:
CORRECT
INCORRECT
B)
An awning is required for the blower if it is installed outdoors, avoiding
motor from being damaged.
C)
The base with which the blower is fastened must be 3 times as heavy as
the blower.

2.2 Installation continued
D)
Install a filter onto the suction inlet of the blower to prevent it from sucking
impurities if the suction inlet is not connected to a pipe.
E)
Keep ventilation gratings and openings clear. The direction flow is
indicated by arrows on the motor end shield and casing.
WARNING
WARNING
F)
Piping needs to be installed to the same level as the central line of the
blower outlet and inlet.
G)
Piping needs to be installed without becoming narrowed, expanded or
being bent at 90 degrees to avoid affecting blower’s operation efficiency.
H)
Piping needs to be fastened independently. Do not mount the piping to the
blower flange or casing to avoid damaging the blower.
I)
The sectional-area curve of the pipe diameter should be no less than 60%
of the sectional-area curve of the blower outlet.
J)
Since the pressure and current of the blower are in direct proportion, it is
necessary to enlarge the diameter of the wind suction/extraction piping to
avoid overloading of the motor.
K)
Keep the fan motor of the blower away from walls or any stuff at a distance
of 50mm to avoid affecting the heat dissipation efficiency of the motor,
preventing it from overheating.
On installation or after maintenance, it is
needed to check that the pump rotation is
correct as specified by the arrows.
Do not operate the blower with the inlet or outlet
blocked or restricted, direct or via nozzles.

2.2 Installation continued
L)
Since the pressure and current of the blower are in direct proportion, it is
necessary to install a pressure relief valve at the air suction/extraction port
to avoid overcurrent failure of the motor. The pressure relief valve listed
below can used in both compressor and vacuum applications.
Mounting:

Type
Thread
Interval

0 ~ 600mbar
M)
Pressure and air friction can easily build up heat around the outlet of the
blower. To lead away the heat, an iron pipe at minimum 1 meter is thus
needed to be connected to the outlet.
N)
On the discharge side, the cover, impeller and silencer housing must not
come into contact with flammable materials (i.e. wood)
O)
The flow noise is reduced by build-in silencers. In the case of free air
intake or exhaust, the noise can be further reduced by attaching additional
silencers. In order to reduce noise emission even further, these units
should not be attached to components that conduct or radiate sound (such
as thin walls, metal plates etc.). If necessary provide intermediate sound-
absorbing layers.

2.2 Installation continued
L)
Serial and parallel connected blowers feature:
Serial connection: (Pressure increases)
Model A
Pressure = 90% of (Model A + Model B)
Air flow = Model A
Model B
Parallel connection (airflow increases)
Model A
Pressure = Model A or Model B
Air flow = Model A + Model B
Model B
CAUTION
Blowers of different horse power can not be
connected with one another.

2.3 Electrical connection
DANGER
A)
The system voltage and frequency must be the same as stated on the
stamp plate. ±5% voltage and ±2% frequency deviations from the rated
values are permitted without the necessity of derating the output. The
joints should be arrange and connected according to the circuit diagram in
the terminal box. The protective earth conductor should be connected to
the terminal
CAUTION
B)
The rated motor current applies for +40ºC air inlet and ambient
temperatures. However at temperatures of +25ºC a 6% higher motor
current is permissible.
C)
Select motor circuit-breakers to match the rated motor current. Where
frequency drives are used as power supply, high frequency current and
voltage harmonics in the motor cables can cause electromagnetic
interference. Therefore shielded motor cables are recommended.
D)
Exceeding the operating speed (see stamp plate) worsens performance
with respect to noise and vibration, and also shortens the life of bearing
grease and the bearing replacement interval. To prevent damage arising
from excessive speeds, it is advisable to consult the supplier concerning
speed limits. Generally rule is approx. 65Hz maximum.
The electric power must be disconnected before
any work is performed on the equipment.
High surface temperatures of more than 70ºC can
occur at the blower. No heat-sensitive parts, such as
standard cables or electronic components, must be
attached or make contact to the surface. If
necessary, protection measures must be provided!

2.4 Commisioning
CAUTION
Note: for safe operation of the blower the following conditions as a
minimum must be observed:
A)
The blower is assembled and operated in accordance with the data on the
stamp plate and information supplied by this manual. (voltage, current,
frequency, connection model and type of protection)
B)
When frequency drives are used, operating speeds are not to be exceeded
according to permitted data on stamp plate. Generally rule is approx. 65Hz
maximum.
C)
The blower is properly assembled, aligned and connected to piping or
hoses as appropriate.
D)
The elevation of the installation location is taken into account when
adjusting the pressure control valves
E)
The direction of the rotation of the blower is as specified.
F)
All fastening screw/bolts, fasteners and electrical connections are
tightened.
G)
The earthing and equalizing potential bonding connections have been
made properly.
H)
All measures have been taken to protect against contact with moving or
energized parts.
If the blower is started up without being connected
or fastened, for example for test purpose, the initial
torque of the motor may cause suddenly movement
resulting tilt of the blower.

CAUTION
CAUTION
DANGER
The inlet must be arranged so that no foreign
elements are sucked in and ejected through the
outlet. (hazard for eyes and skins)
When air is sucked in from the atmosphere, the inlet
must be covered with protective devices (i.e. gratings)
in order to prevent foreign elements including parts of
the body and clothing being sucked in.
Covers which prevent contact with active or rotating
parts are not to be opened during operation.

3 Maintenance
DANGER
DANGER
3.1 Cleaning
A)
When there are any deposits of fluff or dust, clean the entire surface of the
KleeBlower unit.
B)
When required by operating conditions, dismantle by removing screws or
nuts from blower cover. Do not lose these nuts; they will be required for
reassembly! Remove and clean the cover. Clean impeller and housing
after carefully covering rolling-contact bearing. Reassemble in the reverse
order.
WARNING
Before any work is performed on the blower or
equipment, especially covers over moving parts are
removed, the blower should be properly
disconnected from the power supply or frequency
drive. Wait until the rotation of the blower is stopped
completely.
Do not connect the power supply or frequency drive
until the blower has been completely assembled.
After fastening screws/bolts are removed,
some parts are just in centring fits. Even
during proper dismantling it is still possible
that some heavy parts suddenly become
loose and drop off, possibly causing injuries
and damage. Take suitable measures to
secure all parts being worked on.

3.2 Lubrication
A)
The following applies in connection with normal operating conditions (air
intake and ambient temperatures +40ºC max. and permissible total
differential pressure): After approximately 20.000 hours of operation or
after two and a half years at the latest, the rolling-contact bearings and
adjacent spaces should have the old grease removed and be recharged
with new grease. About 50% of the free space in the rolling-contact
bearings and about 65% of the adjacent grease spaces should be filled
with grease.
B)
Closed rolling-contact bearings should be replaced with new ones; their
adjacent grease spaces are not filled with grease.
C)
The information given concerning bearing life and grease life applies to
only this product. Always avoid mixing different types of greases.
D)
Type of grease used in bearings is Mobilgrease XHP220
