Preface
Congratulations on your purchase of the Busch compressor. With
watchful observation of the field’s requirements, innovation and steady
development Busch delivers modern vacuum and pressure solutions
worldwide.
These operating instructions contain information for
–product description,
–safety,
–transport,
–storage,
–installation and commissioning,
–maintenance,
–overhaul,
–troubleshooting and
–spare parts
of the compressor.
Version drive with integrated frequency inverter:
The drive with integrated frequency inverter is subject to a sepa-
rate instruction manual.
For the purpose of these instructions, “handling” the compressor
means the transport, storage, installation, commissioning, influence on
operating conditions, maintenance, troubleshooting and overhaul of
the compressor.
Prior to handling the compressor these operating instructions shall be
read and understood. If anything remains to be clarified please con-
tact your Busch representative!
Keep these operating instructions and, if applicable, other pertinent
operating instructions available on site.

Product Description
Use
The compressor is intended for
–the compression
of
–air and other dry, non-aggressive, non-toxic and non-explosive
gases
Conveying media with a lower or higher density than air leads to an in-
creased thermal and/or mechanical load on the compressor and is per-
missible only after prior consultation with Busch.
Max. allowed temperature of the inlet gas: 40 °C
The compressor is equipped with pressure relief lines between the
pump stage and the gas inlet (a). The pressure relief lines and shaft seal
rings safeguard that no process gases will escape into the environment
of the compressor.
The proper function of the compressor requires ambient pressure
±200* hPa (=mbar) to be present at the gas inlet (a) at any operating
point.
*unless specified otherwise on the nameplate of the compressor
Standard-version:
The gas shall be free from vapours that would condensate under
the temperature and pressure conditions inside the compressor.
Version “Aqua”:
The compressor features the corrosion protection coating CPC and
is capable of conveying water vapour (Úpage 8: Conveying
Condensable Vapours). Conveyance of other vapours shall be
agreed upon with Busch. Conveyance of water or other liquids in
liquid phase increases the power consumption and shall therefore
be avoided (risk of drive overload).
The compressor is intended for the placement in a non-potentially ex-
plosive environment.
The compressor is thermally suitable for continuous operation
(100 percent duty).
Max. permissible number of startings per hour: 12
The maximum allowed pressure on the pressure connection (n) is
0.7 ... 2.0 barg (the nameplate of the compressor indicates the valid
pressure). By means of process control and/or pressure relief valves it
must be made sure that the maximum allowed pressure will not be
exceeded.
The safety valve (m) on the compressor protects the compressor
against overload only. It is no pressure limiting device in terms of
EN 1012-1 for the pressure system. It is not designed for frequent use
and must therefore not be used as a system pressure regulating valve.

CAUTION_a
The safety valve (m) routes compressed product gas back to the gas
inlet (a). This will increase the gas inlet temperature.
Risk of overheating of the compressor!
Continuous operation of the safety valve must be inhibited by the
process monitoring.
Principle of Operation
The compressor works on the claw principle.
The components are dimensioned such, that on the one hand there is
never contact between the two claws or between a claw and the cylin-
der, on the other hand the gaps are small enough to keep the clear-
ance loss between the chambers low.
In order to avoid the suction of dust, the compressor is equipped with
an air filter (j) on the gas inlet.
In order to avoid the suction of solids, the compressor is equipped with
a screen (715) in the gas inlet.
In order to avoid reverse rotation after switching off, the compressor is
equipped with a non-return valve (t, 714).
The compressor compresses the inlet gas absolutely oil-free. A lubrica-
tion of the pump chamber is neither necessary nor allowed.
Cooling
The compressor is cooled by
–radiation of heat from the surface of the compressor
–the air flow from the fan wheel of the drive motor
–the process gas
–the air flow from the fan wheel on the shaft of the compressor
Start Controls
The compressor comes without start controls. The control of the
compressor is to be provided in the course of installation.
Safety
Intended Use

overhaul of the compressor.
The compressor is intended for industrial use. It shall be handled only
by qualified personnel.
The allowed media and operational limits (Úpage 3: Product De-
scription) and the installation prerequisites (Úpage 5: Installation
Prerequisites) of the compressor shall be observed both by the manu-
facturer of the machinery into which the compressor is to be incorpo-
rated and by the operator.
The maintenance instructions shall be observed.
Prior to handling the compressor these installation and operating in-
structions shall be read and understood. If anything remains to be
clarified please contact your Busch representative!

Storage
Short-term Storage
●Make sure that the gas inlet and the pressure connection are
closed (leave the provided plugs in)
●Store the compressor
–if possible in original packaging,
–indoors,
–dry,
–dust free and
–vibration free
Conservation
In case of adverse ambient conditions (e.g. aggressive atmosphere, fre-
quent temperature changes) conserve the compressor immediately. In
case of favourable ambient conditions conserve the compressor if a
storage of more than 3 months is scheduled.
●Make sure that all ports are firmly closed; seal all ports that are not
sealed with PTFE-tape, gaskets or o-rings with adhesive tape
Note: VCI stands for “volatile corrosion inhibitor”. VCI-products (film,
paper, cardboard, foam) evaporate a substance that condenses in mo-
lecular thickness on the packed good and by its electro-chemical prop-
erties effectively suppresses corrosion on metallic surfaces. However,
VCI-products may attack the surfaces of plastics and elastomers. Seek
advice from your local packaging dealer! Busch uses CORTEC
VCI 126 R film for the overseas packaging of large equipment.
●Wrap the compressor in VCI film
●Store the compressor
–if possible in original packing,
–indoors,
–dry,
–dust free and
–vibration free.
For commissioning after conservation:
●Make sure that all remains of adhesive tape are removed from the
ports
●Commission the compressor as described in the chapter Installation
and Commissioning (Úpage 5)

a clearance of minimum 1 m between the compressor and nearby
walls
●Make sure that no heat sensitive parts (plastics, wood, cardboard,
paper, electronics) will touch the surface of the compressor
●Make sure that the installation space or location is vented such
that a sufficient cooling of the compressor is warranted
CAUTION_ad
The compressor is not absolutely gas tight.
Risk of damage to health!
Make sure that the installation space or location is vented such that
in case of conveying media which are dangerous to health no im-
permissible accumulation of conveyed media in the environment of
the compressor will occur.
●Make sure that the installation space or location is vented such
that even in the case of an impaired gas tightness of the
compressor (e.g. due to illegal pressures at the gas inlet, worn
shaft seal rings or clogged pressure relief lines) no impermissible
accumulation of process gas in the environment of the compressor
will occur. Closed cooling air circuits are not permitted.
CAUTION_ac
During operation the surface of the compressor may reach tempera-
tures of more than 70 °C.
Risk of burns!

◆Make sure that the pipe will cause no stress on the
compressor’s connection, if necessary use an expansion joint
●Make sure that ambient pressure ±200* hPa (=mbar) will be pres-
ent at the gas inlet (a) at any operating point
*unless specified otherwise on the nameplate of the compressor
Version “Aqua”, if very humid process gases and/or adverse operating
cycles bear the risk, that condensates remain in the compressor:
◆Provide a shut-off valve, a drip-leg and a drain cock in the suc-
tion line, so that condensates can be drained from the suction
line
◆Provide a valve for the unthrottled suction of ambient air (am-
bient air valve) between the shut-off valve and the compressor
(in order to dry the compressor after process end).
◆Make sure that the anti-pulsation chamber is equipped with a
condensate drain cock (l) (optional; if the condensate drain
cock is missing contact the Busch service)

Risk of damage to the hearing.
Persons staying in the vicinity of a non noise insulated compressor
over extended periods shall wear ear protection.
●Make sure that all provided covers, guards, hoods etc. remain
mounted
●Make sure that protective devices will not be disabled
●Make sure that cooling air inlets and outlets will not be covered or
obstructed and that the cooling air flow will not be affected ad-
versely in any other way
●Make sure that the installation prerequisites (Úpage 5: Installation
Prerequisites) are complied with and will remain complied with,
particularly that a sufficient cooling will be ensured
Conveying Condensable Vapours
Version “Aqua”:
CAUTION_a
Due to the corrosion protection coating CPC the compressor is ca-
pable of conveying water vapour.
Very humid process gases and/or adverse operating cycles can lead
to residual condensates, though, which cause corrosion.
If this is the case, it is necessary to counteract residual condensates
by warming up the compressor, conveyance of ambient air after
process end and regular draining of the anti-pulsation chamber (l).
◆Close the shut-off valve in the suction line
◆Warm up the compressor for approx. 10 minutes
At process start:
◆Open the shut-off valve in the suction line
At the process end:
◆Close the shut-off valve in the suction line
◆Open the ambient air valve
◆Operate the compressor for another approx. 10 minutes
◆Close the ambient air valve
CAUTION_a
During operation of the compressor the anti-pulsation chamber is
under pressure.
Risk of injury when the condensate drain cock is opened!
Drain condensate only when the compressor is shut down and the
pressure connection (n) is vented to atmospheric pressure.
◆Regularly drain condensate from the anti-pulsation chamber (l)
Maintenance
DANGER_age32
In case the compressor conveyed gas that was contaminated with
foreign materials which are dangerous to health, harmful material
can reside in filters.
Danger to health during inspection, cleaning or replacement of fil-

CAUTION_ac
During operation the surface of the compressor may reach tempera-
tures of more than 70 °C.
Risk of burns!
●Prior to disconnecting connections make sure that the connected
pipes/lines are vented to atmospheric pressure
Maintenance Schedule
Note: The maintenance intervals depend very much on the individual
operating conditions. The intervals given below shall be considered as
starting values which should be shortened or extended as appropriate.
Particularly heavy duty operation, such like high dust loads in the envi-
ronment or in the process gas, other contaminations or ingress of pro-
cess material, can make it necessary to shorten the maintenance
intervals significantly.
Monthly:
●Make sure that the compressor is shut down and locked against in-
advertent start up
●Check the inlet air filter (j), if necessary replace
In case of operation in a dusty environment:
◆Clean as described under Úpage 9: Every 6 Months:
Every 3 Months:
●Make sure that the compressor is shut down
●Check the level of the synchronising gear oil
The level shall be slightly above the middle of the sight glass (d).
The level of the synchronising gear should stay constant over the life-
time of the oil. If the level does fall, the gear is leaky and the
compressor requires repair (Busch service).
Every 6 Months:
●Make sure that the housing is free from dust and dirt, clean if nec-
essary
●Make sure that the compressor is shut down and locked against in-
advertent start up
●Remove the acoustic enclosure
Note: Make sure that the foam mats do not get soaked with water
●Clean the fan cowlings, fan wheels, the ventilation grilles and cool-
ing fins
●Mount the acoustic enclosure
Every Year:
●Make sure that the compressor is shut down and locked against in-
advertent start up
●Replace the inlet air filter (j)
●Check the inlet screen (715), clean if necessary
Note: As there is an inlet air filter upstream the inlet screen, the inlet
screen should not show soiling. A soiled inlet screen indicates that the
filter is either broken through or improperly inserted.
Every 5000 Operating Hours, At the Latest after
2 Years:
In case of higher requirements in terms of gas tightness:
◆Replace the shaft seal rings (Busch service)
Every 10000 Operating Hours, At the Latest after
2 Years:
