Function, cross-section
The 400LD(N) duplex filter is suitable for direct installation into pressure lines. It is installed upstream of the components to be protected.
They basically comprise of a filter head (1) with switchover (2) with pressure equalization (3), a threaded filter bowl (4), filter element (5) as well as mechanical optical maintenance indicator with memory function (6).
Via the inlet, the hydraulic fluid reaches the filter element where it is cleaned. The dirt particles filtered out collect in the filter bowl and in the filter element. Via the outlet, the filtered hydraulic fluid enters the hydraulic circuit. By means of the switching lever, you can switch between the two filter housings without operational interruption.
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. All filters have one threaded coupling (7) each as measuring port at the inlet and the outlet. By default, the bleeding is effected via lateral threaded couplings (8).
For sizes 0160 and larger, the filter bowl is standard equipped with a drain plug (9).
With size 1000, the filter bowl has a two-part design. The filter pipe is locked in place in the filter head to prevent unscrewing.
An electronic switching element can be added to the mechanical/optical maintenance indicator in order to integrate the maintenance indicator. The electronic switching element (10) must be attached to the mechanical/optical maintenance indicator (6) and held by means of a locking ring. The electronic switching elements are connected with a mating connector or cable connection.
The electronic switching element must be ordered separately.
Note:
Size 1000 is equipped with a two piece filter bowl (see chapter “Dimensions”). This increases the required service height as shown in the measurement chart.

Assembly
The max. operating pressure of the system must not exceed the max. admissible operating pressure of the filter (see type plate). The assembly is mounted using the rear mounting plate. During assembly of the filter the flow direction (direction arrows) and the required servicing height of the filter element (see chapter “Dimensions”) are to be considered. Ensure that the system is assembled without tension stress. Proper function is only guaranteed in the installation with the 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. The optional electronic maintenance indicator is connected 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.WARNING!
Only install or remove when system is not pressurized. Filter is pressurized. Only remove filter bowl when it is not pressurized. Do not exchange the optical/mechanical maintenance indicator while the filter is under pressure! If the flow direction is not considered during assembly, the filter element will be destroyed. Particle contaminates could enter the system and damage the downstream components!
Important:
Only trained specialists may work on the filter. 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.Correct position of the switching lever during flter element exchange

Information on torques for fastening the SAE connection flange:Only screws of quality class 8.8 must be used. The torques are specified in the relevant standard (ISO 6162-2:2012-12, or are as per AB22-15 for separate flanges). |
Commissioning
Bring the switching lever into central position in order to fill both filter sides and open the pressure equalization valve. Commission the system. Bleed filter by opening the bleed screw, close when fluid 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 in operation. Close the pressure equalization valve.Maintenance
If at operating temperature, the red indicator pin reaches out of the mechanical optical maintenance indicator and/or if the electronic switching element opens/closes the circuit, the filter element is contaminated and needs to be replaced or cleaned respectively. 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. The switch-over lever is on the filter side that is in operation. Open the pressure equalization valve. Switch the filter using the switching lever. Close the pressure equalization valve. Open the lateral threaded couplings at the decommissioned filter side in order to reduce the pressure. Via the drain screw (standard for size 0160 and larger), the fluid on the dirt side can be drained. Unscrew the filter bowl (or end cap if size 1,000). Slightly turn the filter element to remove it from the spigot. Clean the filter components as needed. Check the seals for damage and replace 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, see 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. To fill the maintained filter side, open the pressure equalization valve. The filter is bled via the lateral threaded coupling that is still open. After fluid escapes, close the lateral threaded coupling again. Ensure correct position of the switch-over lever end position. Close the pressure equalization valve.Mating connectors for sensors and valves with connector “K24”, “K35” and “K72”, M12 x 1, with assembled connection line, cable shielded

Directives and standardization
Classification according to the Pressure Equipment Directive
The duplex filters for hydraulic applications according to 51408 are pressure holding equipment according to article 1, section 2.1.4 of the Pressure Equipment Directive 97/23/EC (PED). However, based on the exception in article 1, section 3.6 of the PED, 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. The intended use is only permitted with fluids in group 2 and within the specified operating limits (see “Technical data”).
These filters do not receive a CE mark.
Use in potentially explosive areas according to directive 94/9/EC (ATEX)
The duplex filters according to 51408 are not 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 maintenance indicators with a switching point:
WE-1SP-M12x1 R928028409
WE-1SP-EN175301-803 R928036318
are simple, electronic operating equipment that do not have 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.

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 duplex filters according to 51408 in explosive areas, sufficient potential equalization has to be ensured. The filter is preferably to be grounded via the mounting screws. It has to be noted in this connection that painted and oxidized protective layers are not electrically conductive. During filter element exchanges, the packaging material is to be removed from the replacement element outside the explosive area.
Notices:
All maintenance of the filter should be performed by trained specialists, instruction by the machine end-user acc. to DIRECTIVE 1999/92/EC appendix II, section 1.1. Functional and safety warranty only applicable when using genuine Rexroth spare parts.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.
