1. Suitabilit , general advice
The useful suitability of Positive Displace ent Blower Units ade by Aerzener is the oil-
free conveying and co pressing of air, also of neutral gases in odified design.
In order to ensure an opti u operation, the technical suitability li its have to be
observed.
Intake te perature t1 stated in the order confir ation applies as a bient te perature
at place of installation.
Non-observance of the technical application li its and safety regulations releases the
Aerzener Maschinenfabrik fro warranty and liability regarding replace ent for
consequential da ages. The sa e applies for defects caused by inspections carried out
not in ti e or not properly.

2. Construction, function
Unit:
The unit is delivered with ounted accessories ready to operate.
The following steps are to be effected in addition:
Connect the conveying piping.
Fill up the lube oil.
Install the electrical connection.
Mount the special accessories delivered separately - if there are any.
Motor connection:
The electrical installation has to be effected by an authorized electrical fitter.
The ter inal diagra for the otor can be found in the cover of the ter inal box
as well as in the acco panying docu entation.
The otor- and control voltage is to be connected to a co on network,
where the sealing-in of the power contactor is cancelled in case of an interruption
of circuit.
Alternative: Parallel to the driving otor an electronic onitoring relay is to be
installed which cancels the sealing-in of the power contactor in case of an
interruption of circuit.
Base support:
A torsion-stable, cylindrical container serving as absorption-free discharge silencer as
well as installation basis for blowers with intake silencer, belt drive, belt guard, hinged
otor support and connection casing. The base support rests on flexible achinery
ountings and is to be placed on an even, slope-free underground.
Filter silencer:
This silencer is a co bination of intake-sided silencer and intake filter. The filter aterial
can be cleaned or replaced.
Connection casing:
consisting of: ÜA pressure valve is located for the protection of the blower
against overload.
ÜA non-return flap prevents the blower fro running in reverse
after shut-down.
The discharge-sided piping is connected to the unit via a flexible connection or via a
co pensator.
Accessories: please refer to chapter 11.
Three-lobe rotary pistons. Pulsation decrease by interference (patented).
The conveying cha ber (cylinder) is sealed against the oil cha bers (casing cover and
gear case) by piston ring labyrinth sealings and the driving shaft is sealed by a radial
seal ring.
In case the oil level is too high, oil can penetrate into the conveying cha ber in an
uncontrolled way.
Co pression heat arises upon the co pression procedure. The heat is partly released
via the outer surfaces of blower and conveying pipings to the a bient air. Outer surfaces
and conveying pipings reach te peratures which ay burn the unprotected skin.

3. Precautions prior to and during operation
ATTENTION! Draws the attention to all dangerous situations.
WARNING! Points to direct risks of persons.
Upon receipt the blower is to be checked for da ages during transport and
co pleteness by eans of delivery note and order.
Work safety rules, safety regulations as well as the operating instructions,
are to be observed.
Read the INFORMATION sheet prior to co issioning. Possible notes and
changes indicated herein are to be effected.
The following described tasks are only to be carried out by experts who are fa iliar with
the functions of the blower unit and its co ponents as well as with the safety
regulations to be kept.
This positive displace ent blower eets the European regulations for accident
prevention. Nevertheless, a residual technical risk re ains, with a possibility of
endangering persons and property. To avoid this, operators have to co ply with the
following safety regulations:
ÜIn case of acoustic hood operation the doors are to be locked by eans of the
provided ale triangular wrench and ay only be opened when the otor is
currentless and the fuses are re oved or switched off.
ÜDo not carry out any i proper repair or odification work at the blower. In case of
proble s contact the Aerzen after-sales service!
ÜOperators ust be skilled, introduced to their job and instructed!
ÜPrior to co issioning, operators ust be fa iliar with the protection-, operating- and
onitoring ele ents by eans of these instructions.
ÜUse the achine in accordance with its suitability, keep its perfor ance li its.
ÜRe ove solids, liquids and powdery substances fro the intake range.
ÜSafety appliances, such as e.g. belt guard, in case of acoustic hood design hand
protection and hood ele ent, otor guard / E ergency-OFF etc. ust not be
re oved while achine is running. Risk of injury !
ÜEnsure that the otor is currentless upon working at the unit.
ÜDo not operate when electrical connections, belt guard and pressure valve are
defective or issing.
ÜNo operation with open intake- or pressure socket / blower stage, as: positive
displace ent achines are forced conveying achines with risk of injury in the range
of conveying cha ber.
ÜRisk of burns!
In case of opened or non-existing acoustic hood wear safety gloves when the blower
surface is at operation te perature!
ÜUse ear protection in case of blower operation !
Due to the respective operating condition, the sound pressure level can deviate fro
the entioned operating data. Therefore a sound pressure level higher than 85 dB(A)
can be possible at short notice.
ÜUpon oil change pay attention to the oil te perature.The oil te perature ust not exceed
60 °C. Risk of co bustion at oil te perature exceeding 60 °C !
ÜOnly tools that correspond to the standard and design of the bolts, nuts and fittings ust
be used.
Read irst,
then operate!

english
ÜDanger of poisoning by inhalation and risk of causticization by touching when
using cleaning agents and sprays.
ÜFollow anufacturers instructions as well as applicable regulations!
4. INADMISSIBLE OPERATION METHODS
ÜWrong direction of rotation.
ÜSwitching-on - during run-down.
- upon rotating in reverse direction.
ÜInad issible pressure increase.
ÜRe aining under or exceeding the li it speed.
ÜExceeding the li it-discharge te perature / please also refer na e plate.
ÜPole-changing to lower speed prior to standstill of the otor.
ÜOperation without oil filling.
5. Transport / Assembl
During transport of the blower unit the following points ust be always observed:
ÜThe hinged otor support ust be always locked by eans of the transport locking
screw / refer to page 10.7. Re ove the V-belts fro the pulleys.
ÜProtect the blower unit fro i pacts.
ÜThe unit is to be transported by eans of crane, high-lift truck, elevating truck or
si ilar.
ÜLift the unit only according to sketch.
Concerning units without acoustic hood, transport is effected by application of the
transport devices at three resp. four eyelets (hinged otor support / base fra e) / or
below the transport lugs.
Upon asse bly the following points are to be observed:
ÜUpon dispatch Positive Displace ent achines are preserved for 12 onths and packed
accordingly. Upon a storage for ore than 12 onths, the preservation is to be repeated,
observe TN0 1175.
ÜDuring storage pay atttention to proper preservation, packing and if necessary
nitrogen filling, according to TN0 1175. Test interval every 6 weeks.

Check oil filling screw and drain valve for tight fit and i per eability.
Pay close attention to co issioning re arks and lubrication intervals of
drive otor anufacturer !
Depending on design, cut off rubber nipple on top of the pressure gauges (if existing) or
turn deaeration bracket to OPEN.
Check direction of rotation.
Also refer to red direction of rotation shield on the blower.
No V-belts ust be placed on the otor disc.
Re ove locking screw between pulley and otor casing.
Start driving otor for a short ti e (approx.1 to 2 seconds).
Please also refer to the instructions of the supplier of electric co ponents
resp. of the plant anufacturer.
ATTENTION ! Incorrect direction of rotation during operation will destroy blower.
Upon looking on the driving shaft the blower rotates anticlockwise.
Direction of rotation of drive otor and blower ust be equal.
In case of correct direction of rotation the following tasks are to be effected:
Re ove transport locking screw of the hinged otor support / refer to 10.7.
Check align ent of the pulleys.
Lift hinged otor support by eans of hydraulic jack.
Put on V-belts (refer to chapter 10.7).The V-belts are tensioned by the otor weight.
Close openings for otor driving shaft in belt guard with pre- ounted,
ovable protection covers.
Slide protection covers up to ax. 2 c to otor driving shaft and secure.
Connect pipings with unit ready to operate,
stickers concerning safety instructions ust be legible and safety devices
are to be inspected.
Open slide valves available at the unit. Operation can start.
Switch on drive otor!
Switch off after approx. 20 seconds and verify the s ooth run-down of the blower.
Should pressure valve blow off, switch off i ediately and re ove cause of failure.
Then, switch on again and check EMERGENCY-OFF switch!
Now the unit is ready to operate!

To 160 kW = 6 starts per hour
Fro 200 kW = 3 cold starts or 2 war starts
ÜFor further indications and advice, please refer to the docu entation of the
otor anufacturer.
ÜPlease also refer to chapter 2, otor connection.
8. Shutdown
Shutdown:
By eans of the power switch of the otor. Following standstill of the blower, withdraw
fuses. Ensure that the slide valves in the pipings are closed. Preserve the conveying
cha ber if standstill lasts longer than 6 weeks. Rotate the blower regularly by hand,
in order to prevent da ages which ay arise fro standstill.
In case of danger:
Press EMERGENCY-OFF button.
For details please refer to the instructions of the supplier of electric co ponents resp. of
the plant anufacturer.
9. Operation of compressor units
9.1 with requency converter
The following has to be taken into consideration:
ÜIn case the frequency converter is provided by others the electrical and
echanical characteristics of the driving otor are to be taken into account.
ÜThe ini u frequency ust always be set in a fixed anner.
Upon operation this frequency ust not be re ained under.
ÜThe axi u frequency ust be set under consideration of the axi u
otor speed and the axi u blower- / co pressor speed.
ÜThe run-up ti e of driving otor fro standstill up to ini u speed ay be 3 to 6
seconds.
ÜThe frequency converter ust be designed for operation of a work achine with
constant load o ent.
Min.- or ax. speeds are not to be re ained under or exceeded.
Shutdown

english
ÜThe highest ad issible voltage increase speed of the otor converter is
1200 V/ms. When exceeding the value, e.g. due to too long cables, frequency
converter ake etc. a otor throttle / otor filter coil corresponding to the frequency
converter is to be applied. A renunciation of these co ponent parts ay lead to a
da age of the otor isolation and to a otor breakdown.
ÜThe ax. speed regulation speed on Positive Displace ent blowers /Screw
co pressors after run-up to in. speed for regulation ti e upward and downward is
1 Hz per second.
Min.-frequency = 20 Hz // Max.-frequency = 50 Hz results in a regulation ti e fro
in. to ax. of 30 seconds.
ÜThe ax. current li it of the otor ust not be exceeded.
Observe the details on the otor na e plate.
ÜIn order to avoid operational failures the function "flying restart circuit" ust not be
para eterized in the control of the frequency converter. Upon shutdown of the
frequency converter a re-start is only per itted following co plete standstill of
blower resp. co pressor.
9.2 with pole-changing motor
The following has to be taken into consideration:
ÜBetween a change of otor speed
- fro high to low speed the otor ust have reached each ti e
speed zero.
- fro low to high speed switching can be effected directly, undelayed.
10. Attendance / Maintenance
The attendance / aintenance consists of the following points:
Inspection - Pressure valve test - Exchange o lubricants - Lube
oil regulations - Exchange o V-belts - Intake ilter maintenance -
Attendance
In case of questions, please refer to the Aerzen after-sales service.
Please state the following in your queries:
ÜOrder- and serial nu bers.
ÜDescribe arisen failures / alfunctions as detailed as possible.
ÜSteps taken so far to re ove the failures.
Is the blower sent back to the supplier, the following easures are to be carried out:
ÜDrain the oil, otherwise it is a transport of hazardous goods.
ÜProvide unpolished parts with a preservation oil.
ÜClose blower flanges by eans of blind covers.
