SUMMARY:
Quantity in stock: 0
The 150LD(N) duplex filter is suitable for direct installation into pressure lines. It is installed upstream of components to be protected. Any use in the suction area is not admissible.
It basically consists of a filter head (1) with switch-over fitting (6) and integrated pressure equalization function, two screwable filter bowls (2), two filter elements (3) as well as a mechanical optical maintenance indicator (4).
In case of filters with low-collapse filter elements (= code letter pressure differential A), there is also an integrated bypass valve (11).
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.
For sizes 0160 and larger, the filter bowl is equipped with a drain plug (7).
Via the bleed screws and/or the optional bleed valves ‒ amending information E ‒ (8, 9), the filter side to be maintained can be bled.
Measuring ports in the form of threaded couplings on clean and dirt side are available in the type key under the amending information "M".
Only then will the filter head be drilled accordingly.
By default, the filter is equipped with mechanical optical maintenance indicator (4). The electronic switching element (10) 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.
Notice:
If the maintenance indicator for the element exchange is not observed, the bypass valve will open if the pressure differential increases. In this way, one part of the flow reaches the clean side of the filter without being filtered. Thus, effective filtration is 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 must not be used, filter elements with glass fiber material have to be used instead. Bio-degradable: If filter materials made of filter paper are used, the filter life may be shorter than expected due to material incompatibility and swelling.hydraulic

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 torques”), the flow direction (direction arrows) and the required servicing height of the filter element (see chapter “Dimensions”) are to be considered.
Perfect functioning is only guaranteed in the installation position filter bowl vertically downwards. 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
Bring the switching lever into central position in order to fill both filter sides.
Commission the system.
Bleed filter by opening the bleed screws or bleed valves, close when operating liquid escapes.
Switch the filter into the operating position; to do so, switch the switching lever to one of the two end positions.
The switch-over lever is on the filter side that is out of order.
Maintenance
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. 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. The switch-over lever is on the filter side that is out of order. Observe the switching symbol on the switching lever and/or the switch-over. For pressure compensation and unlocking, pull the switch-over lever and switch to the opposite end position. Open the bleed screw or bleed valve at the decommissioned filter side in order to reduce the pressure. Via the drain screw (from NG0160 fitted by default), the oil on the dirt side can be drained. Screw off the filter bowl – see graphic Assembly aid. 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. The efficiency of the cleaning process depends on the type of dirt and the amount of the pressure differential before the filter element exchange. If the pressure differential after the filter element exchange exceeds 150 % of the value of a brand-new filter element, the filter element made of wire mesh (G…) also needs to be replaced. Detailed cleaning instructions see types 1 and 2 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. To fill the maintained filter side, pull the switch-over lever. The filter is bled via the bleed screw or the bleed valve which is still open. After fluid escapes, close the bleed screw or the bleed valve again. Make sure that the switch-over lever is engaged.
NOTICE!
Assembly and disassembly only with depressurized system! For the filter element exchange refer to “Maintenance”. Tank is under pressure! Maintenance only be specialists. Remove the filter bowl only if it is depressurized! Do not exchange the maintenance indicator while the filter is under pressure! Do not operate the switching lever during the filter element exchange. When disassembling the filter, it has to be observed that the clean side has to be depressurized via the system. Functional and safety warranty only applicable when using genuine Bosch Rexroth spare parts! 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.Electronic switching elements

Classification according to the Pressure Equipment Directive
The duplex filters for hydraulic applications according to 51446 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).
They do not receive a CE mark.
Use in potentially explosive areas according to directive 94/9/EC (ATEX)
The duplex 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 according to DIN EN 13463-1:2009.
According to DIN EN 60079-11:2012, the electronic maintenance indicators 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 60079-14:2008 - in intrinsically safe electric circuits (Ex ib) be used in systems without marking and certification.
The duplex filters and the electronic maintenance indicators described here can be used for the following potentially explosive areas:

Environmental safety and recycling
The used filter element should be disposed of in accordance with the respective country-specific legal regulations of environmental protection.
After completion of the filter life, the components of the filter, in accordance with the respective country-specific legal regulations of environmental protection, are recycled.
