Inline filters
with filter element according to DIN 24550
Features
Inline filters are used in hydraulic systems for separating
solid materials from fluids and lubricating oils. They are
intended for attachment in pipelines.
They distinguish themselves by the following:
▶ Filters for inline installation
▶ Special highly efficient filter materials
▶ Filtration of very fine particles and high dirt holding
capacity across a broad pressure differential range
▶ High collapse resistance of the filter elements
▶ By default equipped with mechanical optical mainte-
nance indicator with memory function
▶ Various, optional electronic switching elements, modular
design
▶ Optional bypass valve integrated in the filter housing
▶ High filtration performance due to the tangential
cyclone-effect flow path
▶ Size according to DIN 24550: 0040 to 0400
▶ additional sizes: 0130, 0150
▶ Nominal pressure 250 bar [3628 psi]
▶ Connection up to G1 1/2; SAE 1 1/2; SAE 24
▶ Operating temperature: –10 °C to +100 °C [+14 °F to +212 °F]

Filter design
Easy selection of the filter size is made possible by the FilterSelect online tool. The filter can be designed using the
operating pressure, flow and fluid system parameters. The required filter rating is based on the application,
the sensitivity to contamination of the components and the environmental conditions.
The program leads you through the menu on a step-by-step basis.
A documentation of the filter selection can finally be created in the form of a PDF file. This file contains the entered
parameters, the designed filter with material number including spare parts, and the pressure loss curves.

Bosch Rexroth AG, RE 51421, edition: 2019-12
Function, section
The 245LE(N) inline filter is suitable for inline installation.
It basically consists of filter head (1), a screwable filter
bowl (2), filter element (3) as well as mechanical optical
maintenance indicator (4). In case of filters with low-pres-
sure-differential-stable filter elements (= code letter pres-
sure differential A), there is an assembled bypass valve (5)
as standard.
Via the inlet, the fluid reaches the filter element (3) where
it is cleaned. The dirt particles filtered out collect in the
filter element (3). Via the outlet, the filtered fluid enters
the hydraulic circuit.
The filter housing and all connection elements are
designed so that pressure peaks - as they may e.g. occur in
case of abrupt opening of large control valves due to the
accelerated fluid quantity - can be securely absorbed. As
of size 0160, the standard equipment comprises a drain
screw (7).
By default, the filter is equipped with mechanical optical
maintenance indicator (4). The electronic switching ele-
ment (8) which has to be ordered separately is attached to
the mechanical optical maintenance indicator (4) and held
by means of a locking ring.
The electronic switching elements with 1 or 2 switching
points are connected via a mating connector according
to IEC-60947-5-2 or via a cable connection according
to EN17301-803.
Outlet Inlet
WARNING!
▶ If the maintenance indicator is not observed while
the element is exchanged, the bypass valve will
open if the pressure differential increases. This
means that part of the volume flow enters unfiltered
into the clean side of the filter. Effective filtration is
therefore no longer guaranteed.

Important information on hydraulic fluids!
▶ For more information and data on the use of other hydraulic
fluids, please refer to data sheet 90220 or contact us!
▶ Flame-resistant – containing water: Due to possible chemical
reactions with materials or surface coatings of machine and
system components, the service life with these hydraulic fluids
may be less than expected.
Filter materials made of filter paper (P) may not be used, filter
elements with glass fiber material have to be used instead.
▶ Biodegradable: If filter materials made of filter paper are used,
the filter life may be shorter than expected due to material
incompatibility and swelling.

Assembly, commissioning, maintenance
Installation
▶ The max. operating pressure of the system must not
exceed the max. admissible operating pressure of the
filter (see type plate).
▶ During assembly of the filter (see also chapter “Tighten-
ing torque””), the flow direction (direction arrows) and
the required servicing height of the filter element (see
chapter “Dimensions”) are to be considered.
▶ Easy filter element exchange is guaranteed in the instal-
lation position filter bowl vertically downwards. The
maintenance indicator must be arranged so it is easily
viewed in operation.
▶ Remove the plastic plugs in the filter inlet and outlet.
▶ Ensure that the system is assembled without tension
stress.
▶ The optional electronic maintenance indicator is con-
nected via the electronic switching element with 1 or 2
switching points, which is attached to the mechanical
optical maintenance indicator and held by means of the
locking ring.
Commissioning
▶ Commission the system.
Notice:
There is no bleed function provided at the filter.
Maintenance
▶ If at operating temperature, the red indicator pin
reaches out of the mechanical optical maintenance
indicator and/or if the switching process in the elec-
tronic switching element is triggered, the filter element
is contaminated and needs to be replaced and cleaned
respectively.
More details see data sheet 51450
▶ The material number of the corresponding replacement
filter element is indicated on the name plate of the
complete filter. It must comply with the material num-
ber on the filter element.
▶ Decommission the system.
▶ The operating pressure is to be release on the system
side.
Notice:
There is no bleed function provided at the filter.
▶ Via the drain screw (from size 0160 fitted by default),
the oil on the dirt side can be drained.
▶ Screw off the filter bowl.
▶ Remove the filter element from the spigot by rotating it
slightly.
▶ Clean the filter components, if necessary.
▶ Check the seals at the filter bowl for damage and renew
them, if necessary.
For suitable seal kits refer to chapter “Spare parts”.
▶ Filter elements made of wire mesh can be cleaned. For
detailed cleaning instructions refer to data sheet 51420.
▶ Install the new or cleaned filter element on the spigot
again by slightly rotating it.
▶ The filter is to be assembled in reverse order.
▶ The torque specifications (Tightening torques chapter)
are to be observed.
▶ Commission the system.
Notices:
▶ All maintenance of the filter should be performed by
trained specialists.
▶ Proper function and safety are only guaranteed if
original Bosch Rexroth filter elements and spare parts
are used.
▶ Warranty becomes void if the delivered item is
changed by the ordering party or third parties or
improperly mounted, installed, maintained, repaired,
used or exposed to environmental condition that do
not comply with the installation conditions.
WARNING!
▶ Assemble and disassemble only with depressurized system!
▶ Filter is pressurized!
▶ Remove the filter bowl only if it is not under pressure!
▶ Do not exchange the optical/mechanical maintenance
indicator while the filter is under pressure!
▶ If the flow direction is not considered during assem-
bly, the filter element will be destroyed. Particle
contaminates could enter the system and damage the
downstream components.

Classification according to the Pressure Equipment
Directive
The inline filters for hydraulic applications according
to 51421 are pressure holding equipment according to
article1, section2.1.4 of the Pressure Equipment Direc-
tive97/23/EC (PED). However, based on the exception in
article1, section3.6 of the PEG, hydraulic filters are
exempt from the PED if they are not classified higher than
category I (guideline1/19).
The fluids from the chapter “Compatibility with approved
pressure fluids” were considered for the classification.
They do not receive a CE mark.

Dust 21 22
Use in explosive areas according to directive 94/9/EC
(ATEX)
The inline filters according to 51421 are no equipment or
components in the sense of directive 94/9/EC and are not
provided with a CE mark. It has been proven with the
ignition risk analysis that these inline filters do not have
own ignition sources acc. to DIN EN 13463-1:2009.
According to DIN EN 60079-11:2012, electronic mainte-
nance indicators with a switching point:
WE-1SP-M12 x 1 R928028409
WE-1SP-EN175301-803 R928036318
are simple, electronic operating equipment that do not
have an own voltage source. This simple, electronic operat-
ing equipment may - according to DINEN60079-14:2012 -
in intrinsically safe electric circuits (Ex ib) be used in
systems without marking and certification.
The inline filters and the electronic maintenance indicators
described here can be used for the following potentially
explosive areas:
Rexroth filters, the filter elements built into them and filter accessories are tested and quality-monitored according to
different ISO test standards:
Pressure pulse test ISO 10771:2015-08
Filtration performance test (multipass test) ISO 16889:2008-06
Δp (pressure loss) characteristic curves ISO 3968:2001-12
Compatibility with hydraulic fluid ISO 2943:1998-11
Collapse pressure test ISO 2941:2009-04

WARNING!
▶ Explosion hazard due to high temperature!
The temperature depends on the temperature of the
medium in the hydraulic circuit and must not exceed
the value specified here. Measures are to be taken so
that in the explosive area, the max. admissible ignition
temperature is not exceeded.
▶ When using the inline filters in accordance with 51
421 in potentially explosive areas, appropriate equipo-
tential bonding has to be ensured. The filter is prefer-
ably to be grounded via the mounting screws. It has to
be noted in this connection that paintings and oxidic
protective layers are not electrically conductive.
▶ During filter element exchanges, the packaging mate-
rial is to be removed from the replacement element
outside the explosive area
