Suitability/General information
The German version of these instructions is the “Original instructions”.
Any version in a language other than German is a “Translation of the original instruc-
tions”.
Aerzener rotary piston machines are suitable for the oil-free conveying and compression
of air and, if specially modied versions are used, various other types of gas.
The technical performance limits must be observed if perfect operation of the equip-
ment is to be ensured in the long term.
The performance limits specied in the order conrmation apply.
The intake temperature t1 specied on the order conrmation serves as the installation
site ambient temperature.
Non-observance of the technical performance limits or the safety information shall
absolve Aerzener Maschinenfabrik of its warranty obligations and its liability to pay
damages or compensation as a result of any consequential damage. The same shall
apply to defects that can be traced back to recommended inspections not being per-
formed correctly or on time.
The vibration behaviour of blowers and compressors with mounted belt pulleys or
couplings is largely determined by the balance quality of the pistons/rotors as well as
the balance of the driving elements.
At Aerzener Maschinenfabrik, the piston/rotor driving shafts are balanced using the
„half-key balancing“ technique.
The belt pulleys/couplings must be used in accordance with the requirements of bal-
ancing type „H“.
The maintenance intervals according to these operating instructions must be followed
and carried out properly. Complying with the maintenance specications will ensure
that the machine retains its value and will also promote operational reliability.

2Construction, function
Jet starter:
Jet starter are supplied as machines to be installed.
Completed with adequate accessory the screw compressor is ready for use.
The screw compressors are suitable for steady operation as well as for installation
in mobile compressor units. Operation in mobile units may be effected only when the
running gear is in idle position. Due to the travelling motion there would be a risk of
high damage to bearing and rotors when the compressor is in full operation. Oil leaka-
ges and interruptions in lubrication oil feed lead to further problems.
Operating oil lling quantity:
In the majority of cases, the directly driven Delta Screw units are not lled with oil
when supplied.
Please observe the machine‘s oil lling quantity and check the level using the mark-
ings on the sight glasses.
Drive:
An combustion engine drives the unit via a exible coupling.
Shutdown of the compressor is effected by stopping the engine.
Resetting may be effected only after standstill of the compressor. Otherwise there will
be the risk of severe breakdown of machinery.
Intake side:
The intake side has to be equipped safely with accessory that meets the operation
requirements.
Please nd the neness of the air intake lter in the enclosed data sheet.
Please note also DIN EN 779 “Particle Air Filter for compartment air technology”.
The lter material has to be changed according to the pollution degree of the absorbed
air and according to the information stated in the maintenance schedule of the manu-
facturer of the aggregate.
Discharge side:
Due to the high compressed discharge temperatures, -> high surface heat emission in
the range of the discharge side can lead to stripping or bubble formation of the var-
nish. This process does not impair the compressor operation and is not considered as
defect of fabrication.
Due to the high compressed discharge temperatures --> high surface heat emission,
stripping or blistering of the varnish may occur in the vicinity of the discharge side.
However, this does not impair the useful properties of the compressor and does not
constitute a defect.
Instrumentation:
Operation without instrumentation, protective devices, etc. is not permitted.

Function:
Aerzener screw compressors are rotary piston machines whose rotors turn uniformly
against each other. Timing gear wheels guarantee contact-free running of the rotors. A
drive shaft including the gear ratio ensures that the rotors run at the required speed.
During operation, the material to be conveyed ows through the intake ange to the
housing and inlet for the rotors. The inlet is closed by means of the rotors rotating, and
the material to be conveyed is directed towards the discharge side. The volume within
the rotors is reduced and the pressure of the material to be conveyed increases.
The rotors and step-up gear feature roller bearings. The compressor and gearbox form
a single assembly unit with a shared forced feed oil lubrication circuit. The oil pump is
ange-mounted on the compressor. It sucks the lubricating oil out of the oil chamber
and pumps it to the relevant point of consumption via a cooler.
Compression heat arises during the compression process. Some of the heat is dissi-
pated into the ambient air via the outer surfaces of the compressor and conveying
pipes.
Outer surfaces and conveying pipes reach temperatures that can cause burns on ex-
posed skin.

complied with.
Read the INFORMATION SHEET prior to commissioning. Any notes or changes sta-
ted on it must be observed.
The tasks described below must only be carried out by qualied personnel who are fa-
miliar with the operation of the machine and its components, and have been instructed
in the relevant safety information.
This rotary piston machine conforms to European safety regulations. Nevertheless,
residual technical risks, which could endanger persons and property, may remain. To
prevent this, operators must take note of the following safety information:
Assembly of the unit
Keep the ange connections sealed during installation.
The ingress of dirt, burring, sputtering, liquids or similar must be avoided.
Remove the seals and covers on the anges just before the ducting connection.
The rotary piston machine can otherwise be blocked or sustain serious damage.
Information about operating data
The machine must be used appropriately and in compliance with the regulations, and
within its performance limits.
The sound pressure level may deviate from that stated in the operating data, depen-
ding on the operating state. A sound pressure level in excess of 85 dB(A) may therefo-
re occur for a short period of time.
Information about general operation
The general safety and industrial accident prevention regulations set down by law
must be taken into account in addition to the information in the operating instructions.
The user has an obligation to only operate the machine in perfect, original condition
and when it is safe to operate.

Check that the machine is not damaged in any way before commissioning.
Do not operate the unit if electrical connections are damaged, defective or not properly
connected.
Do not operate the machine with exposed and accessible inlet or discharge sockets,
for the following reasons: Rotary piston machines are positive displacement machines
which present a risk of injury in the area around the conveying chamber.
Only suitable tools that correspond to the respective standards and design of the
bolts, nuts and screwed connections must be used.
When using cleaning agents and sprays, there is a risk of poisoning from inhalation,
and a risk of burning from coming into contact with them.
Please refer to the material safety data sheets for the operating materials used.
Avoid skin contact with or the swallowing of the lubricant. Risk of poisoning!
Wear protective gloves.
Used lubricants are extremely harmful to the environment and can contain noxious
materials.
Lubricants must be stored and disposed of properly and in an environmentally-friendly
manner.
The appropriately tted rotary piston machines must be used for conveying oxygen. A
lubricant especially suited for operating with oxygen must be used.
Disregarding these warnings is a risk of re and explosion!
Rotary piston machines with separate speed monitoring are equipped with a contact
plate on the drive shaft.
This contact plate rises above the diameter of the belt pulley and reaches operating
speed.
Disregarding the separating protective equipment is a risk of shearing!
Warning signs for hazardous operations
Repairs and modications to the unit must only be carried out in a professional man-
ner. If you have any problems, please contact Aerzener After-Sales Service for assi-
stance.
Before carrying out any retrotting, servicing or maintenance work that requires the
removal of protective equipmen, the power supply must be disconnected and the ma-
chine secured to prevent it starting up.
When replacing and cleaning the lter material (if present)
dust particles and bres may be released into the ambient air. Do not breathe in these
materials. These materials must not reach the unprotected intake area of the rotary
piston machine.
Lubricating and control oil pipes should only be retightened or opened while the ma-
chine is in a depressurised state.
Depressurise conveying ducts before attempting to remove them.
When conveying technical gases, conveying ducts must be rinsed with a neutral gas

Information about the installation site
It is the operator‘s responsibility to use and operate the machine in accordance with its
intended use taking into account the local conditions.
The machine must only be operated in a suitable, well-ventilated installation site. The
installation site must be free from excessive dust, acids, steam and explosive or am-
mable gases.
The installation site must be arranged to avoid risks as a result of the ambient air, the
medium to be convyed or oxygen deciency.
The installation site must be arranged so that the commissioning of the rotary piston
machine does not impose a risk of overheating, re and/or explosion.
The protective equipment provides protection against injury and must not be modied
or bypassed.
When using diesel or petrol drive motors, there is a risk of poisoning if there is insuf-
cient room ventilation. The installation site must be sufciently ventilated. The motor
manufacturer’s operating instructions must also be observed.
Information on operation with an acoustic hood
The acoustic hood is a structural safety component.
During operation with an acoustic hood, all hood elements are to be closed before
starting operation and are only to be opened after the motor has been shut down and
the fuses removed or switched off.
The acoustic hood prevents the risk of injury from rotating and hot components.
If the acoustic hood is opened while the machine is operating,
there is a risk of injury.
When installing and assembling the unit, no sparks or glowing objects caused by, e.g.
welding or separating, are allowed to enter the foam in the acoustic hood. Risk of re!
Risk of glowing embers!
Fire regulations must be adhered to for all “hot work operations” close to the unit.
CAUTION!
When commissioning, sparks, glowing or other re-causing objects could be taken in
from the intake airow and, fanned by the acoustic hood ventilator, set the foam alight.
Risk of re!
No welding or separating is to be done on the acoustic hood as sparks or sputtering
caused by the applied thermal energy could set the foam alight. Risk of re! Risk

Depending on the size and increased re protection regulations, a ame retardant
foam would be applied according to the order.
Information about the event of damage
If the unit produces an abnormal and/or unusual sound, the machine must be shut
down immediately using the EMERGENCY BREAK function.
The energy supply to the drive motor must be disconnected.
If the unit is blocked, the energy supply to the drive motor must be immediately dis-
connected.
The cause of malfunction must be determined.
Aerzener Service can be quickly at hand and provide expert troubleshooting for you.
The unit must not be taken into operation until it is properly functioning.
Information on operating/protecting
the compressor stage and the pressurised pipeline elements
The compressor stage is protected by oil pressure, discharge temperature and•
discharge pressure sensors. The sensors are connected to a fault signalling de-
vice/control at the factory. If the permissible operating parameters are exceeded
or undershot, the fault signalling device/control switches the drive motor off. In the
case of systems without a fault signalling device/control, the customer must install
an appropriate fail-safe control.
To ensure proper operation, the fault signalling device/control must be incorpora-•
ted into the drive motor safety chain in accordance with the circuit diagram. Plea-
se note that the fault signalling device/control and drive motor are fed from the
same
circuit, so that the motor cannot be operated without compressor protection.•
