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.

3 Transport
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.

5.1 Installation Conditions
NOTICE
Use of the machine outside of the permitted installation conditions.
Risk of premature failure!
Loss of efficiency!
• Take care that the installation conditions are fully complied with.
• Make sure that the environment of the machine is not potentially explosive.
• Make sure that the ambient conditions comply with the Technical Data [►31].
• Make sure that the environmental conditions comply with the protection class of the
motor and the electrical instruments.
• Make sure that the installation space or location is vented such that sufficient cooling
of the machine is provided.
• Make sure that cooling air inlets and outlets are not covered or obstructed and that
the cooling air flow is not affected adversely in any other way.
• Check the oil level, see Oil Level Inspection [►20].
• Make sure that all provided covers, guards, hoods, etc. are mounted.
Make sure that the machine is fixed to the concrete base with anchors, see Possible Fix-
ing below.
• Make sure that the machine is secured against movement.
5.2 Blower Unit Installation
The machine must be set up horizontally on a flat surface.
Maximum permissible unevenness of the base / inclination of the machine can be ex-
pressed as follows:
• View from left to right and the front to back : max. 0.5°
We recommend to keep 1 meter space around the machine for the maintenance work.

5.2.1 Possible fixing
WARNING
After being set in its position, the machine must be anchored to the floor.
Otherwise, it could move spontaneously and thus be damaged.
Working procedure for anchoring machine and noise-damping hoods.
• Drill a hole and clean it (A)
• Stick the anchor into the hole (B); and
• Tighten the nut (C)

5.3 Electrical Connection
DANGER
Live wires.
Risk of electrical shock.
• Electrical installation work must only be executed by qualified personnel.
• Make sure that the power supply for the motor is compatible with the data on the
nameplate of the motor.
• The electrical installation must comply with applicable national and international
standards.
• Provide a lockable disconnect switch on the power line so that the machine is com-
pletely secured during maintenance tasks.
• Provide an overload protection according to EN 60204-1 for the motor.
• Make sure that the motor of the machine will not be affected by electric or electro-
magnetic disturbance from the mains; if necessary seek advice from Busch.
• Connect the protective earth conductor.
• Electrically connect the motor.
NOTICE
The motor frequency is below 20 Hz.
Risk of damage to the machine!
