2.1 Operating Principle
The machine with tri-lobe rotors work on the principle of oil-free gas transport.
Two identical lobes rotate in opposite direction in the casing, transporting fixed volume
of air with each turn. There is no contact between the rotors and also between rotor and
casing, therefore process does not require oil in the working area. The machine trans-
ports the gas without increasing the pressure.
Gas is compressed in the machine outlet by the gas that has already transported (blowers
with external compression).
2.2 Application
The machine is intended for transport of air and other dry, non-aggressive, non-toxic
and non-explosive gases.
The machine is intended for the placement in a non-potentially explosive environment.
The machine is suitable for continuous as well as intermittent operation.
Permitted environmental conditions, see Technical Data [►31].
NOTICE
Chemical compatibility of the process gases with the machine component materials.
Risk of corrosion inside the blower working area which can reduce performance and its
lifetime!
• Check if the process gases are compatible with those following materials:
- Cast iron
- Steel
- Aluminium
- Fluoroelastomer (FKM/FPM)
• In doubt, please contact your Busch representative.

WARNING
Suspended load.
Risk of severe injury!
• Do not walk, stand or work under suspended loads.
WARNING
Lifting the machine using the motor eye bolt.
Risk of severe injury!
• Do not lift the machine using the eye bolt fitted to the motor. Only lift the machine as
shown.
NOTICE
In case the machine is already filled with oil.
Tilting a machine that is already filled with oil can cause large quantities of oil to in-
gress into the casing.
• Drain the oil prior to every transport or always horizontally transport the machine.
• Check the machine for transport damage.
If the machine is secured to a base plate:
• Remove the machine from the base plate.

4 Storage
• Seal all apertures with adhesive tape or reuse provided caps.
If the machine is to be stored for more than 3 months:
• Wrap the machine in a corrosion inhibiting film.
• Store the machine indoors, dry, dust free and if possible in original packaging
preferably at temperatures between .
NOTICE
Long storage time (over 6 months).
The blower shaft should be rotated by hand periodically, at least once a month, in or-
der to renew the grease on the bearing races and keep a periodical record. Failure to
carry out this procedure could invalidate the product warranty.
NOTICE
Long storage time (more than 6 months).
For long storage time or storage in a warehouse with substantial fluctuations in tem-
perature and/or an aggressiv atmosphere, the rotary lobe blower must be prepared in a
special procedure from Busch Vyroba CZ s.r.o. (according to customer information dur-
ing order preparation).
All specific preparations and procedures must be preserved during a storaging all the
time. The rotary lobe blower must be wrapped in a special VCI foil all the time during
storaging.

NOTICE
Incorrect direction of rotation.
Risk of damage to the machine!
• Operation in the wrong direction of rotation can destroy the machine in a short time!
Prior to start-up, ensure that the machine is operated in the right direction.
The intended rotation direction of the motor is defined by the specific instruction label
stuck on the machine.
• Jog the motor briefly.
• Watch the fan wheel of the motor and determine the direction of rotation just before
the fan wheel stops.
If the rotation of the motor must be changed:
• Switch any two of the motor phase wires.

• Make sure that the connection lines cause no stress on the machine‘s connection; if
necessary use flexible joints.
• Make sure that the line size of the connection lines over the entire length is at least as
large as the connections of the machine.
In case of long connection lines it is advisable to use larger line sizes in order to avoid a
loss of efficiency. Seek advice from your Busch representative.

7.1 Maintenance Schedule
The maintenance intervals depend very much on the individual operating conditions. The
intervals given below are considered as starting values which should be shortened or ex-
tended as appropriate. Particularly harsh applications or heavy duty operation, such as
high dust loads in the environment or in the process gas, other contamination or ingress
of process material, can make it necessary to shorten the maintenance intervals signifi-
cantly.
NOTE
The machine must be turned off at the service breaker and secured against wrongful re-
activation during all service work.
Interval Maintenance work
Every 6 months • Carry out a visual inspection and clean the machine
from dust and dirt.
• Check the electrical connections and the monitoring
devices.
Every 32000 hours • Recommend planning a preventive overhaul for every
32000 hours operation.
According to the motor
manual
• Check the motor. Lubricate the motor if necessary.
(In accordance with the motor manual).
7.2 Maintenance Inlet Filter
The inlet filter must be cleaned regularly or more often depending on application. The
frequency depends on the application, but the filter must be cleaned at least once every
six months.
The filter must not be washed.
The filter’s dirt level is monitored by the supplied filter gauge that is built into the v-belt
cover or the cabinet front.
Cleaning with compressed air does not ensure a 100% clean wrap filter, it is therefore
recommended to replace it with a new one.
Interval Maintenance work
After 10-20 operating hours • Check the inlet filter and clean if necessary. (See
clean or change inlet filter, point 5)
Monthly (or more often de-
pending on application).
• Check the inlet filter and clean if necessary. (See
clean or change inlet filter, point 5)
Half - yearly • Change the inlet filter (or more often depending on
application). (See clean or change inlet filter, point 5)
Yearly • Change the inlet filter (or more often depending on
application). (See clean or change inlet filter, point 5)
