Features
Inline filters are used in hydraulic systems for separating
solid materials from fluids and lubricating oils.
They come with the following features:
▶ Filter 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 rating of the filter elements
▶ Equipped standard 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 tangential,
cyclonic flow path
▶ Additional configurations available for special fluids
▶ Size as per DIN 24550: 0040 to 1000
▶ Other sizes: 0130, 0150
▶ Nominal pressure: 350 bar [5,079 psi]
▶ Connection sizes up to G2; SAE 2"; SAE 24
▶ Operating temperature: -10 °C to 100 °C [14 °F to 212 °F]

Inline filter | 350LEN0040 to 1000; 350LE0130, 0150 7/24
RE 51422, edition: 2015-03, Bosch Rexroth AG
Function, cross-section
The 350LE(N) inline filter is designed for direct installation
into pressure lines.
It consists primarily of a filter head (1), a threaded filter
bowl (2), a filter element (3) and a mechanical optical
maintenance indicator (4). For filters with low collapse
filter elements (= pressure differential code letter A), a
bypass valve (5) comes standard.
The fluid passes through the inlet to the filter element,
where it is cleaned. Any dirt particles filtered out collect in
the filter element. The filtered fluid then enters the hydrau-
lic circuit through the outlet.
The filter housing and all connection elements are
designed so that pressure spikes — as they may occur, e.g.,
due to an accelerated fluid quantity from large control
valves opening abruptly — can be safely absorbed. Sizes
0160 and larger come with a drain screw (6) standard.
Size 1000 comes with a two-part filter bowl, with the filter
bowl fixed to prevent the bowl from spinning in
the filter head.
An electronic switching element (7) can be added
to the mechanical optical maintenance indicator in order
to integrate it into an electric circuit. The electronic
switching element must be attached to the mechanical
visual maintenance indicator and held with the locking ring
supplied. The electronic switching elements are connected
with a mating connector or cable connection.
The electronic switching element must be ordered
separately.
InletOutlet
WARNING
▶ If the maintenance indicator is ignored when an
element change is required, there is the possibility the
filter will go into bypass and contaminated oil will pass
to the clean side of the filter outlet. Therefore the
filtration effectiveness is no longer guaranteed.

Important information on hydraulic fluids:
▶ For more information and data on the use of other hydraulic
fluids, see data sheet 90220 or contact us.
▶ Flame-resistant, aqueous: Due to possible chemical reactions with
materials or machine and system component surface coating, the
service life with these hydraulic fluids may be less than expected.
Do not use filter materials made of filter paper P, use filter
elements with glass fiber filter material 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
Assembly
▶ The max. operating pressure of the system cannot
exceed the max. admissible operating pressure
of the filter (see name plate).
▶ When assembling the filter (see also “Tightening
torques”), note the flow direction (arrows) and the
required servicing height of the filter element
(see “Dimensions”).
▶ Filter element exchange is made easiest when the filter
bowl is oriented downward. Ensure the maintenance
indicator is easily visible.
▶ Remove the plastic plugs in the filter inlet and outlet.
▶ Make sure power is disconnected during assembly.
▶ The optional electrical maintenance indicator is con-
nected using the electronic switching element with
1 or 2 switching points, which is placed on the mechan-
ical visual maintenance indicator and held in place
by a locking ring.
Commissioning
▶ Commission the system.
Important:
The filter has no bleeding mechanism.
Maintenance
▶ If the red indicator pin rises out of the mechanical
visual maintenance indicator and/or the electronic
switching element switches at operating temperature,
the filter element is dirty and has to be replaced/
cleaned. For more details, see data sheet 51420.
▶ The material number of the correct replacement filter
element is on the name plate of the complete filter. Verify
that it matches the material number on the filter element.
▶ Decommission the system.
▶ Release operating pressure on the system side.
Important:
The filter has no bleeding mechanism.
▶ Drain the oil on the dirt side using the drain screw
(size 0160 and larger).
▶ Unscrew the filter bowl (or base if size 1000).
▶ Slightly turn the filter element to remove it
from the spigot.
▶ Clean the filter components as needed.
▶ Check the seals on the filter bowl for damage and
replace them as needed.
For compatible seal kits, see “Spare parts”.
▶ Wire mesh filter elements can be cleaned. For detailed
cleaning instructions, see data sheet 51420.
▶ Slightly turn the new or cleaned filter element to install
it on the spigot.
▶ Assembly is reverse of removal.
▶ Note the torque specifications (“Tightening torques”).
▶ Commission the system.
Important:
▶ Only trained specialists may work on the filter.
▶ The safety and functionality of the filter are only guar-
anteed with original Bosch Rexroth spare parts.
▶ The warranty will be void if the delivery item is
modified or improperly mounted, installed, main-
tained, repaired or used by the ordering party or a
third party, or exposed to environmental conditions
exceeding our installation conditions.
WARNING
▶ Only install or remove when system is not pressurized.
▶ Filter is pressurized.
▶ Only remove filter bowl when it is not pressurized.
▶ Do not replace maintenance indicator when filter
is pressurized.
▶ Failure to observe flow of direction during assembly
will cause filter element to be damaged beyond repair.
Particles will enter the system and damage down-
stream components.

Classification according to the
Pressure Equipment Directive
Inline filters for hydraulic applications as per 51422 are
considered pressure holding equipment under Article1
Section 2.1.4 Pressure Equipment Directive 97/23/EC
(PED). However, under Article1 Section3.6 PED, hydraulic
filters are exempt from the PED if they are not classified
higher than Category I (Guideline1/19).
The fluids from “Compatibility with permitted hydraulic
fluids” were considered for the classification.
They do not receive a CE mark.

Gas 1 2
Dust 21 22
Use in explosive areas as per Directive 94/9/EC (ATEX)
Inline filters as per 51422 are not equipment or compo-
nents in terms of Directive 94/9/EC and do not receive a
CE mark. The ignition risk analysis showed that these
inline filters do not have their own ignition sources as per
DIN EN 13463-1:2009.
According to DIN EN 60079-11:2012, electronic mainte-
nance indicators with a switching point:
WE-1SP-M12x1 R928028409
WE-1SP-EN175301-803 R928036318
are considered simple electronic operating equipment that
does not have its own voltage source. This simple elec-
tronic operating equipment may — according to
DINEN60079-14:2012 — be used in intrinsically safe
electric circuits (Ex ib) in systems without requiring
marking and certification.
Inline filters and the electronic maintenance indicators
described here can be used in the following explosive areas:

WARNING
▶ Explosion hazard due to high temperature.
Temperature is based on temperature of medium
in hydraulic circuit and cannot exceed this value. Take
steps to make sure max. admissible ignition tempera-
ture is not exceeded in explosive area.
▶ Make sure potential equalization is sufficient when
using 51422 inline filters in explosive areas. Ground-
ing the filter with mounting screws is recommended.
Note that paint and oxide protective coating are not
electrically conductive.
▶ When replacing filter element, remove packaging mate-
rial from explosive area around replacement element.
Directives and standardization
Important:
▶ Safety and functionality of the filter are only guaran-
teed with original Bosch Rexroth spare parts.
▶ Maintenance may only be performed by specialists on
instruction of the owner in accordance with Directive
1999/92/EC Annex II Section 1.1.
