Filter elements from Filtration Group Industrial are optionally available with patented
e-protect filter technology. This prevents electrostatic discharges during the filtrationof low conductive fluids such as zinc- and ash-free synthetic oils and protects thesystem from damage. The friction that occurs when the oil flows through the fabricof conventional filters often leads to electrostatic discharge - occasionally with drastic consequences. In addition to damage to the filter sheets, varnish is produced,
which causes the oil to age quickly. With e-protect technology, the electrostatic
charge is dissipated from the filter surface, preventing damage. The FGI e-protect
construction extends the service life of the filters and components while maintaininga high separation rate.

OUR PULSESHIELDTM FILTERS DON’T GIVE WAY
There is a pulsing movement in many hydraulic systems and the innovative pleated star geometry from Filtration Group Industrial resists it. Filtration Group Industrial has developed an effective
solution for pressure fluctuations with its patented PulseShieldTM compression sleeve technology.
Pulses occur in almost every hydraulic circuit when pistons move or valves are switched quickly.
The pleated star is pressed against the inner core by our compression sleeve and provides stability
to the geometry. This prevents blocking of the pleats. The separation efficiency remains high evenwith pressure fluctuations. The PulseShieldTM technology also prevents particles that have alreadybeen separated from the filter medium from being released again by these pulsations.

DUPLEX FILTERSDivision of labor enables continuous
operation at the highest performance level
Duplex filters from Filtration Group Industrial areparticularly suitable for use in machines and motorsthat must operate continuously. The filter elements
can easily be changed during operation with asimple turn of our ergonomically designed handle.
A special lever in the handle allows switching andpressure compensation with one hand. Thanks tothis patented one-hand switch, the system cancontinue to run without interruption. When filter
elements need to be replaced, a standard maintenance indicator signals the production floor. In
continuous running filter systems, the elements canbe removed and replaced in one filter housing while
the other filter housing takes over. In larger filter systems, the elements can be removed from the top.
The systems meet the highest demands in terms ofergonomics and economy.

RETURN LINE FILTERS

Dirt sluice on the way back
Return line filters are now an essential componentof modern hydraulic and lubrication systems. The
proven design of the Pi series filters ensure safe andeconomical production processes in the fluid system. The return line filter collects the dirt before it isreturned back to the hydraulic reservoir. As a result,fewer particles enter the tank, which reduces wearon the intake pump and the downstream components in the fluid circuit. Highly efficient filter elements used in return line filter applications ensurethat proper ISO fluid cleanliness classes can be
maintained. Especially in mobile applications suchas special vehicles and agricultural and construction
machinery, return line filters play an important role ofa working filter with defined oil cleanliness.

Protection from oil mist

Air breathers play a central role in the filtrationof transmission, lubricating and hydraulic oil byprotecting the systems from external contamination. The ambient air that passes throughopenings in hydraulic fluid reservoirs usuallycontains particles of dirt or moisture. These
contaminants limit the performance of thesensitive components in the hydraulic system or
damage them. Filtration Group Industrial offers
efficient air breathers in a variety of designs andconfigurations, equipped with filter elements
for all specified operating conditions and any
required degree of cleanliness. Filter housings
made of corrosion-resistant sheet steel orfiberglass-reinforced plastic are available inmany sizes and with various connection options
to suit the respective application. Other variants
are supplied by the proven products of sistercompany Zinga. All air breathers have one thingin common: they ensure that hydraulic systems
run much longer in high-performance operation
than with conventional filters.

Oil separators are essential for compressor manufacturers because
they offer advantages such as energy efficiency, life cycle costs andenvironmental friendliness. End users are seeking to reduce the total
cost of ownership of compressed air system. In addition, compressors
are becoming ever more compact in order to take up as little space aspossible. Filtration Group Industrial responds to these challenges bycontinuously optimizing its oil mist solutions. The oil separators meet
two central requirements: They separate the oil added to the air flow
for lubrication, sealing and cooling to a residual oil quantity of 1 mg/m³
with relatively no impact on the resulting differential pressure compared
to conventional oil separators.

OIL FILTER MODULE PI 8300

OIL DEWATERING

Small, compact
and complete

Coalescer filter: protection
from power stealing water

Oil filter modules are self-sufficient systems consistingof an electric motor, a gear pump and a filter. They wereoriginally developed for lubricant filtration in wind turbine
gearboxes. They were developed as independent
systems with high performance in a compact design.
Filtration Group Industrial offers a filter module in two
variants, for a volume flow of 110 l/min and 220 l/min.
In combination with an oil cooler, the Pi 8300 achieves
optimum separation results and prevents overheatingof the lubricating oil. As a result, wear in the gearbox isminimized.

Water plays a role in many applications of hydraulic systems. It can be usedboth as an operating medium and for cooling. However, if it gets into the fluid of
hydraulic and lubrication systems, an acid forms in conjunction with the oil molecules, which corrodes components or causes so-called steam bubbles. Thisacid will cause significant damage in hydraulic valves and pumps. The hydraulicfluid itself is not as efficient as an energy carrier with the addition of water.
Free water in hydraulic and lubricating oil systems has expensive consequences in the long run: costly repair work, necessary shutdown of thesystem and expensive replacement of the diluted hydraulic fluid.
Filtration Group Industrial developed filters based on the coalescer principle,
which separates free water from oil efficiently, cost-effectively and without
the use of chemicals. The water droplets finely distributed in the oil collect on
specially arranged filter materials and are efficiently separated. Filtration Group
Industrial offers high-performance filter types for use in mobile applications,
stationary hydraulic systems, paper machines, on ships and in fuel filtration
for diesel engines.

Although oil filter modules from Filtration Group Industrial are predominantly installed as main flow filters inwind turbines, they are also used for off-line filtration. In
hydraulic systems in paper or rolling mills, the Pi 8400
oil filter modules can be used in conjunction with yourin-plant machinery and hydraulic equipment to achieve
and maintain proper ISO cleanliness classes. When water-absorbing filter is specified, FGI filter elements canremove free water and oil ageing substances from thehydraulic fluid in addition to other contaminants.

MAINTENANCE INDICATOR

Reliable signal generator for filter replacement
Filtration Group Industrial filters are designed toremove a lot of dirt over a long period of time. They
should always be replaced before their efficiency is
reduced and their dirt holding capacity is reached.
Maintenance indicators from Filtration Group Industrial detect changes in pressure in hydraulic fluids
and lubricating oils as a result of contamination. The
sensors register the negative pressure in suction filters,
the differential pressure in pressure filters and the

dynamic pressure in return line filters. When a pressure is exceeded, the indicator signals changes to theoperator via a pressure gauge, optical or optical-electrical switches. Filtration Group Industrial offers three
types of maintenance indicators, which can either
be installed on new filter systems or retrofitted into
an operational system. By indicating when the filter
should be changed, they contribute to the economical
operation of the system.

PREFORMANCE TESTING IS THE
TRADEMARK OF A QUALITY FILTERAt Filtration Group Industrial, product quality is always core of our filters. The high demands placedon the performance of filter elements, modules and systems by our customers demand that we
engineer a quality product. In order to meet our customer’s high standards, every innovation iscarefully validated and tested before it goes into serial production.

THE POWER IS IN
THE QUALITY.
Friedrich Nietzsche, German philosopher

With the MULTIPASS TEST, the filter element mustshow that it’s properly capturing the contaminates aspromised: The separation efficiency and dirt holding
capacity are determined here.
The FLOW MEASUREMENT records important filter
characteristics which are measured by the pressure
increase in the volume flow.
At the PULSATION TEST, the housing and filter heads
are subjected to powerful pressure: This shows how
long the parts can withstand continuous pressure pulsations with low, medium and high pressure.
At the BURST PRESSURE TEST everything goesto pieces - and that‘s exactly what needs to happen.
The filters must withstand extreme pressure. A burst
pressure test is conducted to make sure that the filter
will continue to last at pressures far greater than thenormal operating pressure. Otherwise, it goes back to
the development workshop.
The COLLAPSE PRESSURE TEST also tests for failureof the filter as the fluid passes from the outside of filter tothe inside as a result of extreme differential pressure. They
must withstand a pre-defined differential pressure.

During the BUBBLE POINT TEST, the seal of the filter
elements is put to the test. Compressed air is introduced at the filter inlet and then increased until a streamof bubbles occurs. We design our seals so they do notleak at higher pressures.
The FLOW ENDURANCE RESISTANCE of a filter
element is also tested. This determines how long thefilter element can withstand a pulsating load.
The HIGH PRESSURE TEST is used to test in accordance with the TÜV or by marine companies such as
DNVGL, Det Norske Veritas or Lloyd‘s Register.
In the MICROSCOPICAL EXAMINATION, theparticles that have been filtered out of the liquid or arepresent in an oil sample are examined in detail.
The FTIR SPECTROMETER is used to detectorganic compounds or chemical changes in the oil.
This provides crucial information for the selection of theappropriate filter.
The FLENDER TEST helps to reduce excessive oil
foaming: Two gears supply air to a hydraulic or transmission oil to check how quickly an air-oil dispersion
concentration harmful to the hydraulic system is formed.

Filtration Group Industrial continues toinnovate and develop solutions that meetor exceed the requirements of leadingmachine designers and manufacturers.
