2.4
General functional description
The operator must follow the safe working practices,
instructions, procedures that this manual describes for
safe operation. The maintenance personnel must be
adequately trained, and have read and thoroughly
understood this ‘Operation and maintenance manual’.
Decals are affixed at specific locations of the compressor
and they illustrate very important safety precautions.
2.3.1 Precautions during installation
 Ensure that you fasten all loose parts before lifting. Select
the appropriate lifting equipment by considering the local
safety regulations, size and weight of the compressor.
Operate the lifting equipment carefully within the safe
operating limits. Ensure all necessary personal protective
equipment's (PPEs) is close at hand during this operation.
 Maintain a cool and clean ambient for the compressor
and ensure that the air inlet is not obstructed. Make
arrangements to reduce the moisture entry through the
incoming air.
 Remove protection such as caps, plugs, desiccant bags
before connecting the air line pipes.
 Remove the red colored protective clamps from the
airend and motor while commissioning the compressor.
 Do not use frayed, damaged or worn hoses. Distribution
pipes and connections must be of the correct size and
suitable for working pressure.
 Make sure that the aspirated air by the compressor is
free of flammable fumes, vapors and particles, to
prevent internal fire or explosion.
 For remotely controlled compressors and auto-start
compressors, provide a clear caution stating:
“DANGER” – Remotely controlled machine and will
start without notice
 Ensure the operator is located far away from the intake
of the compressor.
 Position the after-cooler discharge pipe in a way that it
is free to expand under heat and is not in contact with
or close to flammable materials.
 Do not exert external force on the air outlet valve and
keep the connected pipe always free of strain.
 Make available adequate cooling air must be made
available for the compressor particularly air cooled
compressors. Make sure that exhausted air does not
circulate back to the intake or cooling system.
 Make the electrical connections according to the legal
standards and earth the compressor suitably. Provide a
sufficient number of fuses and other protective devices
to protect the compressor against short circuits. Good
practice is to provide an isolating switch nearby the
compressor.
 Install manual valves behind non-return valves (NRV) to
isolate each compressor in multi-compressor systems.
Do not rely on NRV for isolating pressure systems.
 Do not bypass, remove or adjust the safety devices or
other attachments residing on the compressor. Every
installed pressure vessel or auxiliary outside the
compressor should have pressure relieving device or
devices, as required.
 Danger! Be aware that compressed air used for
breathing or food processing must meet O.S.H.A.

2.3.2 Precautions during operations
 When switching on remotely controlled compressors
ensure that no one is checking or working on the
compressor at that time.
 Before starting, ensure that no tools or any loose parts
remain inside the compressor.
 Do not operate the compressor if a possibility exists
that it could inhale flammable or toxic fumes, vapors or
particles.
 Do not operate the compressor below or above its
operating limits.
 Wear ear protectors if you work in an environment
where the sound pressure level reaches or exceeds 90
dB (A).
 Keep all the compressor doors shut during operation.
For carrying out routine checks, the doors should open
only for short durations not more than 10 minutes.
Wear ear protectors when opening a door.
 Keep hands, feet, floors, controls and walking surfaces
clean and free of water or other liquid to minimize the
possibility of slips and falls.
Pressure release
 Know that annual servicing of the safety valve is
necessary. It should be checked at the prescribed
pressure for operation.
 Use correct tools for maintenance and repair work.
Do not allow the manufacturers’ rated safe operating
pressure to exceed for pipes, valves, filters and other
fittings.
 It is hazardous to point the compressed air directly
towards any personnel. Keep personnel out of the line
of the discharge air when opening hoses or other points
of compressed air discharge.
 Use only the correct type and size of hose end fittings
and connections. When blowing through a hose or
airline ensure that the open end stays securely. A free
end will whip and may cause injury. Make sure to
depressurize a hose fully before disconnecting it.
 Release all the pressure in the compressor system
before servicing or performing any maintenance
activity.
 Do not engage in horseplay with air hoses. Serious
injury or death may result.
 Do not use air at a pressure greater than 2.5 bar.g (36
psi.g) for cleaning purpose.

minimizes the risk of creating a current path through
the heart.
 Conduct repairs only in a clean, dry, well-lit and
ventilated area.
 Do not leave the compressor unattended with open
electrical enclosures. If necessary to do so, disconnect
the power to the compressor at the source and lock it
out so that power is not in advertently restored.
 Disconnect, lock out, and tag the power source prior to
attempting repairs or adjustments, turning the
compressor manually or handling ungrounded
conductors.
 All electrical installation must be in accordance with
recognized electrical codes and any local health & safety
codes.
 Recognize that only authorized and qualified trained
personnel should carry out any electrical work on the
compressor.
 Regularly check that all electrical connections are tight
and in good condition.

practices before maintenance work.
 Use appropriate tools for all maintenance works.
 Use only genuine spare parts. Refer the section “Use
genuine spare parts” in “Maintenance” chapter.
 Ensure that the compressor is cooled down before
maintenance is performed.
 Springs under tension or compression store energy.
Uncontrolled release of this energy can cause serious
injury or death. Be cautious while performing the
maintenance of components loaded with springs (for
example minimum pressure valve, safety valve etc.).
 Display a warning sign that says “Maintenance under
progress, don’t switch on” near the start switch.
 Isolate the compressor from the air line (discharge) and
disconnect the power by opening and locking the
isolating switch before maintenance.
 Prior to attempting repairs or adjustments, disconnect
the power at the source and verify at the compressor
that the circuits have de-energized. This minimizes the
possibility of accidental start-up or operation, especially
when the compressor is remotely controlled.
 Open the oil filler cap only when the compressor is not
running and is not pressurized. Shut down the
compressor and bleed the receiver tank to zero internal
pressure before removing the cap.

2.8
General functional description
 If you are going to switch on remotely controlled
compressors must ensure that nobody is checking or
working on the compressor at that time. A warning sign
near the equipment’s start button is mandatory.
 Wait up to five minutes to ensure that the air in the air-
oil separator tank is released to start routing
maintenance.
 Vent all internal pressure prior to opening any line,
fitting, valve, drain plug, connection or other
components such as filters. Vent pressure by popping
up the safety valve.
 Display a maintenance chart near the compressor to
easily identify the maintenance intervals of regular
service items.

General functional description
2.4.1 Air circuit
The atmospheric air enters into the airend through the air
intake system. The intake filters (pre filter and air filter)
prevents the entry of foreign particles (such as dust) into
the airend. The intake valve regulates the amount of air
sucked into the airend. The opening and closing of the
intake valve are controlled by the pneumatic pulse line
actuated by an electrically controlled solenoid valve. The
clog indicator fitted in the air filter turns red when the
filter is clogged.
The filtered air enters into the airend where it mixes with
the injected oil. The injected oil acts as a coolant to
maintain optimum temperature. It also seals the leaks
between the rotors and the housing and lubricates the
bearings and gears. The airend consists of two counter-
rotating intermeshed helical screws - the male and the
female rotors - which are driven by electric motor. The air
-oil mixture is trapped between the rotors of the airend
and is progressively compressed.
After being compressed, the air-oil mixture enters with
high velocity into the air-oil separator tank where it
undergoes a unique 3 stage separation process which
removes maximum oil content. This highly efficient 3 stage
separation process uses the impact velocity of air-oil
mixture along with centrifugal action, which makes the
mixture very lean. The final stage of this separation
consists of passing the lean mixture through the air-oil
separator element which leaves the air with an oil content
of < 1 ppm.
The oil separated and collected in this element is then
returned to the airend through the oil return line. The air
passes through a minimum pressure valve (MPV). It
maintains a minimum differential pressure which is
required for circulation of oil within the compressor unit.
The compressed hot air is cooled in the after cooler and is
separated of any moisture content by the moisture
separator. The cooled and moisture free compressed air is
now discharged to the external receiver, ready to be used.
2.4.2 Oil circuit
The oil in the air-oil separation tank after being separated
is fed into the airend. The oil either gets diverted to the oil
cooler or oil filter or both depending upon the
temperature. The thermal valve governs and controls the
oil flow path. The oil before being injected into the airend
is filtered. An orifice is provided in oil flow path towards
the airend to control the oil flow. The whole oil circulation
circuit in the compressor is operated solely by the
differential pressure maintained by the minimum pressure
valve (MPV) and doesn't require any additional pump.
2.4.3 Drive system
The airend transmission is powered by an electric
induction motor through a coupling. When the compressor
is turned ON, the motor is started in star mode and takes
6 to 9 seconds to change over to delta mode. During this
period the intake valve remains closed and thus the motor
starts without load. In delta mode, the motor speed
stabilizes, the solenoid valve energizes after 10 seconds of
change-over to reduce load on the motor, the blow down
valve is closes, intake valve opens and the compressor
starts loading. For compressors with variable frequency
drive (VFD), speed of the motor gradually increases within
30 seconds (ramp-up time) while the intake valve remains
in the closed position. This ensures very little starting load.
Next, the intake valve opens and the system starts
building up pressure. An adaptor ring connects the airend
and the motor. It also helps in maintaining the coupling
alignment. The coupling element acts as a safety interlock
and it is the first one to fail when coupling elements
become over loaded. This architecture saves the whole
drive system from failure. Malfunctioning of the coupling

General functional description
element will result in noise and vibration. Anti-vibration
mountings reside below the air end and the motor. This
configuration reduces the transmission of vibration from
airend and motor to the structure, reducing noise and
ensuring reliability of mounted parts on the structure.
2.4.4 Control system
Load - Unload
Depending on the demand for compressed air from the
application at a particular time, the compressor needs to
respond accordingly. The compressor, therefore operates
in either loading or unloading mode to meet this
requirement. The primary objective of these modes is to
save energy and reduce wear and tear on the machine.
The control system ensures a smooth start without
overloading the motor. The compressor is started in star
mode, during which most of the compressed air is vented
to the atmosphere. This mechanism helps prevent
overloading the motor. In delta mode the motor speed
stabilizes, the solenoid valve energizes after 10 seconds of
change-over to reduce load on the motor, the blow-down
valve is closes, and the compressor starts loading.
When the receiver pressure reaches the maximum limit, a
signal arrives the solenoid valve from the control system.
Next, the inlet valve actuates and closes, and the
compressor runs in unloading mode. If unloading mode
continues for more than 5 minutes, i.e., compressed air is
consumed and thus no decrease in pressure occurs, the
system stops and switches to standby mode. If a drop in
pressure occurs in the receiver, the compressor returns to
loading mode automatically.
Suction modulation
When you operate a compressor without VFD, capacity
control occurs via a pressure regulator (for selected
models). When the consumption of air is less than the FAD
of the compressor, the line pressure will start increasing.
Whenever the line pressure goes up constantly beyond the
set pressure, the pressure regulator bleeds the excess air
to the atmosphere thereby reducing the amount of flow
into the actuator. The actuator is spring loaded, which, in
turn, closes the intake valve slightly and enables capacity
control. Similarly when the consumption of air is more
than the FAD, the line pressure starts decreasing and the
actuator progressively opens the intake valve. This
regulation is called intake modulation by throttling.
VFD modulation
VFD is an efficient way of controlling capacity as per
demand. In a compressor with VFD the power of
compressor varies proportionally with capacity reduction.
The VFD tunes the frequency, thereby adjusting the speed
based on the change in line pressure. The incoming flow
will automatically reduce because of reduced speed of the
motor. Conversely speed increases when line pressure
goes down below working pressure.
2.4.5 For retro-fitment of Standalone VFD
with Compressor (C) version in field
1. Change the bearings to insulated type for motors
>=90kw at Non Drive End side of Motor
2. Turndown only upto 50% for conversion models
(considering the motor speed) i.e. motor frequency range
is 50 - 25 Hz for 50Hz variant and 60 - 30Hz for 60Hz
variant. No pressure turndown is applicable
3. Run the compressor in the VFD operating range (50 to
25Hz) and skip the frequency in VFD controller (within +/-
1Hz) if abnormal noise / vibration is observed
4. Change the thermal element from 65°C to 75°C
