2.1 Operating Principle
The machine works on the claw principle.
The MINK is fully air-cooled thanks to an integrated fan in the drive unit.
In order to avoid solids from entering, the machine is equipped with an inlet screen (IS).
In order to avoid reverse rotation after switching off, the machine is equipped with a non-return
valve (NRV).
2.2 Intended Use
WARNING
In case of foreseeable misuse outside the intended use of the machine.
Risk of injuries!
Risk of damages to the machine!
Risk of damages to the environment!
●Make sure to follow all instructions described in this manual.
The machine is intended for the suction of air and other dry, non-aggressive, non-toxic and non-ex-
plosive 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 machine is designed for indoor installation, in case of outdoor installation, ask your Busch rep-
resentative in order to take specific precautions.
The machine is not capable of maintaining ultimate pressure.
●The minimum allowed ultimate pressure is to be read from the nameplate of the machine.
●By means of process control and/or vacuum relief valves it must be made sure that the mini-
mum allowed ultimate pressure will not be underrun.
The machine is suitable for continuous operation.
Note: The non-return valve (NRV) shouldn't be used as a non-return or shut off valve for the System.
The non-return valve is only to protect the pump.
If the machine needs to be maintained after shutdown:
●Provide an additional manual or automatic operated non-return valve in the suction line.
Permitted environmental conditions, see Technical Data [➔36].

Standard Features
Vacuum Relief Valve
The ultimate pressure is limited by a vacuum relief valve (VRE). The vacuum relief valve is adjusted
ex-works to the minimum permitted ultimate pressure shown on the nameplate (NP).
If the machine operates with a variable speed drive using the pressure control mode, the ultimate
pressure is limited electronically by the variable speed drive and the pressure control.
Pressure Monitoring
Only for the version: Pressure Control
The pressure transmitter (PSA) is to detect high inlet pressure.
The additional pressure transmitter (PSA) is to detect high process gas pressure.
Optional Accessories
Inlet Filter
The inlet filter protects the machine against dust and other solids in the process gas. The inlet filter
is available with a paper or polyester cartridge.

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.
~1 m ~1 m
~1 m ~1 m
●Make sure that the environment of the machine is not potentially explosive.
●Make sure that the ambient conditions comply with the Technical Data [➔36].
●Make sure that the environmental conditions comply with the protection class of the motor and
the electrical elements.
●Make sure that the installation space or location is protected from weather and lightning.
●Make sure that the installation space or location is vented such that sufficient cooling of the ma-
chine 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.
●Make sure that enough space remains for maintenance work.

5.2 Connecting Lines / Pipes
WARNING
Rotating Parts.
Risk of severe injury!
●Do not operate the machine without suction / discharge connection installed.
●Remove all protective covers before installation.
●Make sure that the connection lines cause no stress on the connection of the machine; if neces-
sary 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 effi-
ciency. Seek advice from your Busch representative.
NOTICE
Flow of potential condensate from the piping to the vacuum pump.
Risk of damage to the machine!
●Make sure that the vacuum pump suction and exhaust connection pipes are installed in such a
way as to prevent the flow of potential condensate from the piping to the vacuum pump.
●Busch recommends the use of the optional horizontal inlet filter and the water separator to col-
lect the condensate and prevent it from flowing into the pump.
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(s):
– G2 – without inlet filter (IF)
– G2 ½ - with inlet filter (IF)
Depending on the specific configuration ordered, other connection dimensions may apply.

5.2.2 Discharge Connection
NOTICE
Discharge gas flow obstructed.
Risk of damage to the machine!
●Make sure that the discharged gas will flow without obstruction. Do not shut off or throttle the
discharge line or use it as a pressurized air source.
Connection size(s):
– R1 1/4
Depending on the specific configuration ordered, other connection dimensions may apply.
Unless the aspirated air is discharged to the environment right at the machine:
●Make sure that the discharge line either slopes away from the machine or provide a liquid sep-
arator or a siphon with a drain cock, so that no liquids can flow back into the machine.
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.
For oil type and oil capacity see Technical Data [➔36] and Oil [➔37].
The oil level should stay constant over the lifetime of the oil. If the level does fall, this indicates a leak
and the machine requires repair.
