2.1 Operating Principle
The machine works on the claw principle.
The MINK MM is fully air-cooled thanks to an integrated fan in the drive unit.
2.2 Application
The machine is intended for the compression of air and other dry, non-aggressive, non-
toxic and non-explosive gases.
Conveying of other media leads to an increased thermal and/or mechanical load on the
machine and is permissible only after a consultation with Busch.
The machine is intended for the placement in a non-potentially explosive environment.
The maximum allowed pressure on the discharge connection (OUT) must not exceed the
value indicated on the nameplate (NP).
The machine is suitable for continuous operation.
Permitted environmental conditions, see Technical Data [►19].
The machine is a built-in pump designed for vacuum packaging machines.
2.3 Start Controls
The machine comes without start controls. The control of the machine is to be provided
in the course of installation.
2.4 Standard Features
2.4.1 Safety Valve
The safety valve (SV) protects the machine against overload only. It is not designed for
frequent use and must therefore not be used as a system pressure regulating valve.
2.4.2 Inlet Filter with Silencer
The inlet filter (IF) protects the machine against dust and other solids in the process gas.
The inlet filter is available with a paper or polyester cartridge. The external silencer (SI)
reduces the inlet gas noise at the machine suction inlet (IN).

• 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.
• Make sure that the oil sight glass (OSG) remains easily visible.

5.2 Connecting Lines / Pipes
• Remove all protective caps before installation.
• 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 very 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.
5.2.1 Suction Connection
NOTICE
Ingress of foreign objects or liquids.
Risk of damage to the machine!
If the inlet gas contains dust or other foreign solid particles:
• Install a suitable filter (5micron or less) upstream from the machine.
Connection size:
– Without connection. The inlet gas is sucked from the ambient air of the machine.
Depending on the specific order, other connection dimensions may apply.
• Make sure that the gas is drawn without obstruction.
5.2.2 Discharge Connection
Connection size:
– G1 1/4
Depending on the specific order, other connection dimensions may apply.
5.3 Filling Oil
NOTICE
Use of an inappropriate oil.
Risk of premature failure!
Loss of efficiency!
• Only use an oil type which has previously been approved and recommended by
Busch.

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.

7 Maintenance
WARNING
Machines contaminated with hazardous material.
Risk of poisoning!
Risk of infection!
If the machine is contaminated with hazardous material:
• Wear appropriate personal protective equipment.

CAUTION
Hot surface.
Risk of burns!
• Prior to any action requiring touching the machine, let the machine cool down first.
NOTICE
Using inappropriate cleaners.
Risk of removing safety stickers and protective paint!
• Do not use incompatible solvents to clean the machine.
CAUTION
Failing to properly maintain the machine.
Risk of injuries!
Risk of premature failure and loss of efficiency!
• Respect the maintenance intervals or ask your Busch representative for service.
• Shut down the machine and lock against inadvertent start up.
• Vent the connected lines to atmospheric pressure.
If necessary:
• Disconnect all connections.
7.1 Maintenance Schedule
The maintenance intervals depend very much on the individual operating conditions. The
intervals given below are desired to be considered as starting values which should be
shortened or extended as appropriate. Particularly harsh applications or heavy duty oper-
ation, such as high dust loads in the environment or in the process gas, other contamina-
tion or ingress of process material, can make it necessary to shorten the maintenance in-
tervals significantly.
Interval Maintenance work
Monthly In case of an inlet filter being installed:
• Check the inlet filter cartridge, replace if neces-
sary.
Every 3 months • Check the oil level, see Oil Level Inspection [►13].
Every 6 months • Clean the machine from dust and dirt.
Every 20000 hours • Change the oil.
The change interval of 20000 operating hours is valid
for Busch approved oils only. The change interval de-
pends very much on the operating conditions. Border-
line operation may reduce the change interval down to
approximately 5000 operating hours. Other oils may re-
duce the change interval.
Every 6 years • Have a major overhaul on the machine (contact
Busch).
