The 445LEN inline filter is suitable for installation into pressure lines.

It basically consists of filter head (1), a screwable filter bowl (2), (size 1000 filter pipe with filter cover), filter element (3) as well as mechanical/visual maintenance indicator (4). In case of filters with low-pressure-differential-stable filter elements (= code letter pressure differential A), there is also an assembled bypass valve (5). Via the inlet, the hydraulic fluid reaches the filter element (3) where it is cleaned. The dirt particles filtered out settle in the filter element (3). Via the outlet, the filtered hydraulic 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 (6). With size 1000, the filter bowl has a two-part set-up. In this connection, the filter pipe is secured in the filter head against rotation.

By default, the filter is equipped with mechanical/visual maintenance indicator (4). The electronic switching element (7) which has to be ordered separately is attached to the mechanical/visual 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.

Order option Supplementary information -7

The standard outlet is closed by means of a SAE blind flange. The outlet is arranged to the top; in this way, the flow direction is angled by 90° to the top.

Order option Supplementary information -9

The bleeding is arranged at the hexagon of the filter bowl. The drain is located laterally at the filter head vis-à-vis the clogging indicator.

1)	Servicing height for filter element exchange

Installation

The max. operating pressure of the system must not exceed the max. adm. operating pressure of the filter (see name plate).

During assembly of the filter (see also chapter “Tightening 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 installation position filter bowl vertically downwards. For filters with order option ‒ supplementary information 9 ‒ , the installation position is filter bowl vertically upwards. The maintenance indicator must be arranged in a well visible way.

Remove the plastic plugs in the filter inlet and outlet.

Ensure that the system is assembled without tension stress.

The optional electric maintenance indicator is connected via the electronic switching element with 1 or 2 switching points, which is attached to the mechanical/visual maintenance indicator and held by means of the locking ring.

Commissioning:

Commission the system.

Notice:

There is no bleeding provided at the filter. However, some sizes and/or variants have optional threaded couplings which may also be used for bleeding.

If at operating temperature, the red indicator pin reaches out of the mechanical/visual maintenance indicator and/or if the switching process in the electronic 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 number on the filter element.

Decommission the system.

The operating pressure is to be release on the system side.

Via the drain screw (from NG0160 fitted by default), the oil on the dirt side can be drained.

Screw off the filter bowl (and/or bottom with NG1000).

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.

Please note:

Screw in the filter bowl to the stop, then screw out the filter bowl by 1/8 to 1/2 rotation again so that the filter bowl does not get stuck due to the pressure pulsation and can be easily released in case of maintenance works.

The torque specifications (“Tightening torques” chapter) are to be observed.

Commission the system and with order option - Amending information 9, bleed the filter.

Notice!

Assembly with filter bowl to the top is only admissible with the order option - Supplementary information 9. This variant ensures safe bleeding.

Safety instructions!

Assembly and disassembly only with depressurized system!

Filter is under pressure!

Remove the filter bowl only if it is depressurized!

Do not exchange the mechanical/visual maintenance indicator while the filter is under pressure!

If the flow direction is not considered during the assembly, the filter element will be destroyed. Particles will get into the system and damage downstream components.

Notes:

All works at the filter only be trained specialists.

Functioning 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.

Inline filters are used in hydraulic systems for separating solid materials from the fluids and lubricating oils. They are intended for attachment in pipelines.

Classification according to the Pressure Equipment Directive

These inline filters for hydraulic applications are pressure holding equipment according to article 1, section 2.1.4 of the Pressure Equipment Directive 97/23/EC (PED). However, on the basis of 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).

For the classification, fluids from the chapter “Compatibility with permitted hydraulic fluids” have been taken into consideration.

They do not receive a CE mark.

Use in potentially explosive areas according to directive 94/9/EC (ATEX)

These inline filters 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, the electronic maintenance indicators with one switching point:

WE-1SP-M12x1 and WE-1SP-EN175301-803

are simple, electronic operating equipment not having an own voltage source. This simple, electronic operating 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:

	Zone suitability
Gas	1	2
Dust	21	22

Possible circuit according to DIN EN 60079-14

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 potentially explosive area, the max. admissible ignition temperature is not exceeded. When using the filters in potentially explosive areas, appropriate equipotential bonding has to be ensured. The filter is preferably to be earthed via the mounting screws. It has to be noted in this connection that paintings and oxidic protective layers are not electrically conductive. Maintenance only by specialists, instruction by the machine end-user acc. to DIRECTIVE 1999/92/EC appendix II, section 1.1. During filter element exchanges, the packaging material is to be removed from the replacement element outside the potentially explosive area. Functional and safety warranty only applicable when using genuine Rexroth spare parts.
