SECTION 1 - SAFETY REGULATIONS
EAGLE ROTA NOVA screw Compressors
are designed and manufactured with safety
as a prime consideration; industry-accepted
safety factors have been used in the design.
Each compressor is checked at the factory
for safety and operation.
Failure to observe these notices could
result in severe personal injury, death,
property damage and/or compressor
damage.
♦
♦
♦
♦
Disconnect the unit from its power
supply and lockout before working
on the unit.
This
unit
is
designed
for
compression of normal atmospheric
air only. The intake air must not
contain any inflammable vapors or
exhaust vapors.
Relieve all internal pressure to the
compressor prior to servicing. Do
not depend on the check valves to
hold system pressure.
Do not change the pressure setting
of the pressure relief valve or
replace the pressure relief valve
with a plug.

4.2
Compressor Main Components
4.2.1 Intake Air Filter:
The air filter is integrated in a housing and
mounted directly on the air intake fitting. The
filter serves to protect the compressor unit from
impurities found in the surrounding environment.
Controlling pollutants at the air inlet will deliver a
longer component service life and trouble free
operation.
4.2.2 Separator Cartridge:
The separator cartridge is the air/oil-separating
element of the screw compressor unit. The
cartridge is screwed on the filter support of the
separator tank by a fitting. The air/oil separator
element is used to recover the finely dispersed
residual oil in the form of drops after preseparation. The compressed air is technically oil
free but performance of the filter is also affected
by temperature, operating pressure, flow and
type of oil being used.
After the separation process the oil is returned to
the compression stage via the oil scavenge
orifice.
This orifice should be inspected
whenever an air/oil separator is scheduled for
replacement. Make sure that the scavenge
orifice is unrestricted.
Please refer to the
maintenance section.
4.2.3 Oil Suction Check Valve:
This valve prevents the back flow of oil from the
air end to the purifier cartridge when the unit is
switched off which causes a pressure difference
in the system. The valve is located within the
screw compressor and is maintenance-free.
4.2.4 Minimum Pressure Valve:
The minimum pressure valve assembled on the
air supply side of the compressor, maintains a
minimum pressure inside the body of the
compressor. The pressure ranges between 4560 PSI depending on the type of compressor.
This pressure is necessary for good oil
separation and lubrication. At the same time,
the valve acts as a check valve, which prevents
the backflow of compressed air from the system
or from the pressure tank into the screw
compressor. For instructions on adjustments to
this minimum pressure valve please refer to the
maintenance section of this manual.
-15-
4.2.5 Oil Filter:
The oil filter at the beginning of the
lubrication circuit prevents solid particles
from entering the circuit and damaging the
rotors and bearings. The NK-series use a
replaceable spin-on oil filter and has an oil
bypass valve, which is opened in the case of
cold, very viscous oil or if the filter is very
contaminated. This prevents the compressor
from being damaged by an insufficient
supply of oil. The SCI-series use a metallic
mesh filter mounted internally that can be
easily inspected and cleaned. This filter may
occasionally need to be replaced depending
on the demands on the filter.
4.2.6 Air-Oil Circuit:
The oil-air mix is conducted through the
separator tank by means of the rotors in the
screw compressor block. Immediately after
this, the pre-separation of the oil from the
compressed air takes place in the
separation tank by means of the reduction of
the flow speed combined with a change in
the flow direction. The compressed air is
conducted over the oil level of the sump to
the air de-oiling unit after a further change in
the flow direction. In the air de-oiling unit,
the residual oil is precipitated from the
compressed air, and collects in the
separator chamber. From there, it is sucked
via a non-return valve into the compressor
chamber, where there is a lower pressure
than final pressure. For visual monitoring,
the residual oil is channeled through an oil
inspecting glass from the air de-oiling unit.
Under normal operating conditions, the air
de-oiling unit is maintenance free. The
replacement intervals are about 3000 to
6000 operating hours.
The service life
depends primarily on the degree of pollution
of the intake air and proper handling of the
maintenance intervals of the oil filter and the
air filter.
4.2.7 Oil Thermovalve:
When the cold unit is started, the thermal
bypass valve controls the pressurized oil flow
coming from the oil separator back to the
compressor via the oil change filter.
The
thermovalve on the SCI7 and SCI8 and NK100
units are located internally, on the NK60 unit it is
external. The oil cooler is bypassed until the oil
reaches a specified temperature. When the oil
temperature starts rising above the value
marked on the oil thermovalve, the oil is
gradually conducted through the oil cooler.
Once the oil temperature has reached a value of
approximately 15°C more, the oil thermovalve is
closed and the cooler is fully used. The oil
thermovalve provides for constant temperature
and viscosity of the lubricating oil. A further
function is that it prevents condensate from
building up inside the oil tank, which may affect
the lubricating characteristics of the oil.
4.2.8 Oil/Air Cooling System:
The after cooler used with the screw compressor
is a combi cooler used to cool the lubricating oil
of the compressor and the compressed air. The
oil and air in the aftercooler is air cooled by
means of a fan attached to the shaft of the
motor. Air-cooled aftercooler is provided to
reduce the temperature of the compressed air to
approximately 15°C of the ambient temperature.
This temperature is dependent on the ambient
temperature, relative humidity and barometric
pressure of the air entering the compressor.
4.2.9
Control Panel (Optional Item)
Refer to the wiring diagram sent with this
compressor. A wiring diagram is also located
inside the control panel.
4.3
Capacity Control Systems
Intake Control
4.3.1 SCI7
The intake valve acts as a check valve, which
will prevent oil and compressed air from
discharging through the inlet filter when the unit
is shut off. A solenoid, which is controlled by a
pressure switch, causes the full air stream to
recycle from the discharge to the suction. In
order to keep the system pressurized air is
circulated inside the compressor head until the
compressor is brought on load again.
NOTE: If there is no control panel, the solenoid
valve needs to be wired on site to the
motor starter.
-16-
4.3.2 SCI8
The intake valve on this unit also will act as a
check valve during shutdown. A solenoid, which
is controlled by a pressure switch, is used to
close the inlet valve when the system pressure
reaches the upper set point of the pressure
switch. This will prevent the compressor from
continuing to take in air and the internal
pressure is lowered. The compressor will be
running unloaded. The power consumption in
this case will be minimized. When the system
pressure drops to the lower pressure set point, a
signal is sent to reopen the inlet valve and the
compressor is again operating fully loaded.
4.3.3 NK60 and NK100
A pneumatic control unit controls air intake. The
pneumatic control valve opens and closes the
intake proportionally and continuously as a
function of the compressed air consumption.
During no-demand the intake valve is completely
and automatically closed to stop air from
entering the compressor unit. At this time a
small amount of air is still being allowed to flow
into the compressor through a by-pass valve.
This valve only allows enough air to enter the
compressor in order to keep the oil circuit unit
pressurized. Air and Oil from the compressor
will not be released through the intake of the air
compressor due to inlet check valve.
SECTION 5 - INSTALLATION
5.1
Location
Locate the compressor on a level surface that is
clean, well lighted and well ventilated. Ambient
temperature should not exceed temperature
listed on the EAGLE ROTA NOVA screw
compressors data sheets. (Failure to meet this
may result in a high air temperature shutdown.)
short term, unusually heavy demands in excess
of the compressor capacity, it also serves to
precipitate some of the moisture that may be
present in the compressed air. The air receiver
should be equipped with a drain trap. If the tank
is not drained regularly, the capacity of the
receiver is reduced by liquid accumulation.
5.4
Clean, fresh air, in sufficient quantity, is required
for proper compressor operation. Do not locate
the unit where the hot exhaust air from other
compressors or heat generating equipment may
be drawn into the unit. There should be 1.5 ft
between the air intake and the wall.
Before installation, the electrical supply should
be checked for adequate wire size. Do not
connect the screw compressor unit to a voltage
other than that specified on the motor nameplate.
5.5
NOTICE
!
5.6
Piping connections
Sensing Compressor Rotation
Compressor rotation must be checked prior to
start-up or after changes have been made on
the electrical feed line. (This must be done with
the belts removed.) A wrong sense of rotation
for more than 2 seconds results in extreme
damage to the screw compressor and warranty
coverage will be voided.
Never join pipes or fitting by soldering.
Never use plastic, PVC, ABS pipe or rubber.
5.3
WARNING
Eagle Rota Nova bare screw
compressors are shipped dry from
the factory. Do not attempt to
operate the compressor before filling
it with the proper type of oil. This
could cause extreme damage to the
compressor.
“Warranty will be voided”
WARNING
This compressor should not be
installed in an area that may be
exposed to a toxic, volatile or
corrosive atmosphere, nor
should toxic, volatile or
corrosive agents be stored near
the compressor.
5.2
Fluid Level
The compressor package is filled at the factory
with the correct amount of oil. The fluid level is
monitored while in operation by observing the
sight glass on the SCI-series. Refer to Figure 1.
Do not overfill as the excess fluid will carry over
into the plant air distribution system.
If the room is not properly
ventilated the compressor
operating temperatures will
increase and cause the high
temperature switch to shut the
unit off.

SECTION 7 - MAINTENANCE
!
WARNING
Never assume the compressor is
ready for maintenance or service
because it is stopped. The
compressor could start
automatically at any time. The
following procedure should be
followed for your safety when
preparing for maintenance.
•
Close the manual air shutoff valve on the
delivery side of the compressor, usually
located between the receiver and the plant
air system. This will prevent airflow backup
from the air system to the compressor.
NEVER depend on the check valve alone to
isolate the air system
•
Pull the safety ring on the pressure relief
valve and wait for the pressure in the system
to be completely relieved before removing
any components from the compressor.

•
After complete drainage, reinstall the drain
plugs and refill the compressor.
•
Run for two (2) minutes, then recheck oil
level.
•
Record the oil change in your maintenance
log.
•
Dispose of the used oil in accordance with
local waste disposal regulations.
7.4
Oil Filter
To replace or clean the oil filter element.
(SCI models)
7.2 - Figure 2.
!
The filter should be cleaned after the first
hours of operation at the same time as the
oil change. Thereafter the filter should
cleaned every 2000 hours of operation
replaced at every oil change.
WARNING
Hot oil under pressure can cause
severe injury. Do not remove the
oil fill cap or attempt to add oil to
the compressor while it is in
operation. Make sure the unit is
fully stopped and depressurized
before adding oil.
7.3
Changing Oil
•
Shut down the compressor
•
Pull the pressure relief valve to test for
pressure
•
Slowly unscrew the oil cap
•
If you are only cleaning the filter element,
there is no need to remove the oil from the
oil cooler. Only remove the oil from the oil
cooler when planning an oil change.
Remove the drain plug located at the end of
the air-end drain tube.
•
Remove the four Allen-head cap screws that
are holding the round oil filter housing in
place.
Eagle Pump & Compressor recommends the
use of its Eagle ISO 68 synthetic compressor oil.
Rota Nova ISO 68 can be used between 3,000
to 6,000 hours depending upon application.
Note: Draining the oil should be done while
the oil is still warm. This will carry away

•
To remove the filter, the same cap screws
can be utilized as jacking bolts to forcefully
assist in pulling out the filter housing. Insert
two of the cap screws into the threaded
holes provided on the housing. Screw in the
two cap screws equally until the cover has
backed out from the housing. The assembly
can then be pulled out by hand.
•
Once removed, the filter element can be
cleaned in a light solvent or replaced as
required. Also inspect the O-ring on the oil
filter.
•
Install the filter using a new gasket and
tighten the cap screws. DO NOT
OVERTIGHTEN.
•
Fill the compressor with new oil to the
proper level.
under severe operating conditions such as dusty
environments, high humidity, or under sustained
high operating temperature conditions, it should
be replaced more frequently, as needed. (Refer
to Figure 3.)
7.5 - Figure 3
(NK models)
The oil filter cartridge should be replaced after
the first 500 hours of operation at the same time
as the first oil change. Thereafter the filter
should be replaced every 2000 hours of
operation.
•
Shutdown the compressor and lockout.
•
If the compressor is excessively hot, let it
cool until the oil filter cartridge can be
handled safely.
•
Shut down the compressor and lockout.
Unscrew the oil filter cartridge "counterclockwise to remove”. Dispose of the used
filter cartridge in accordance with local
waste disposal regulations.
•
Unscrew the cartridge by turning it counterclockwise by hand
•
Screw in the new air/oil separator cartridge
and snugly tighten by hand
•
Re-start the compressor and check for
leaks.
•
The SCI models and the NK60 have a
scavenge line orifice sight glass. Oil return
movement should be observed through the
sight glass when the compressor is
operating and fully loaded. If no movement
or minimal movement is observed, the
orifice could be restricted or plugged. To
clean the orifice, remove the sight glass to
gain access for
cleaning.
(Refer to
Figure 4.)
•
The NK100 and NK160 have no external
sight glass. The scavenge orifice is located
inside a fitting on the oil return line external
to the air-end. On these models the oil
return line must be removed and the
scavenge orifice inspected visually while the
compressor is stopped
•
•
Lubricate the gasket/seal on the new filter
cartridge.
•
Before mounting the new filter cartridge,
hold it upright and fill it with the same type of
oil as you are using in the compressor
partial fill for NK100 (oil filter on an angle).
•
Screw on the new oil filter cartridge by hand
”clockwise to install” Make sure it is snug.
•
Restart the compressor and check for leaks
after it has run for one hour.
7.5
Air/Oil Separator Cartridge
Both the SCI and NK series compressors use a
disposable type, spin-on air/oil separator
cartridge. It should be replaced at least once a
year or at 6000 hours of operation under ideal
conditions, whichever comes first. However,

Routinely blow the dirt off the cooler fins. We
recommend using compressed air, soap and
water jet, or a cleansing agent, depending
on the type of build-up plugging the cooler.
Scavenge
Sight Glass
Under ideal ambient conditions, the air/oil
cooler should be inspected every week for
build-up. In extremely dusty environments,
the cooler may have to be cleaned every
day.

Air Filter
Under ideal operating conditions, the air inlet
filter should be replaced every 2,000 hours.
However, when operating in
dusty
environments, more frequent replacement is
necessary.

NOTICE

7.6
Oil/Air Cooling System
For the operational safety of the screw
compressor unit, clean the cooler regularly.
Keep the cooling fins of the cooler clean.
This is a prerequisite for achieving maximum
component efficiency. Adequate cooling
means low oil, low air temperatures and
delivers a longer service life.
-21-
Any contaminants entering a
screw compressor are
immediately mixed with the oil at
the compression point, and
injected into the oil filter and the
air/oil separator. Controlling
pollutants at the air inlet will
deliver a long component service
life and trouble-free operation.
