MATERIAL: R928000418
SUMMARY: Duplex Filter Al/St <=40bar NW50-100
Due to extremely high demand, please call 888-651-5712 for availability
Function, section: NG0400 … 0630 / 0120
The 40FLD(N) duplex filter is suitable for inline installation. It basically consists of two filter housings (2) with one switch-over fitting (1), two filter covers (3), two filter elements (4) as well as mechanical optical maintenance indicator (8).
Via the inlet, the hydraulic fluid reaches the filter element (4) where it is cleaned. The dirt particles filtered out collect in the filter element (4). Via the outlet, the filtered fluid enters the hydraulic circuit.
Switching between the two filter housings is carried out by means of the switching lever.
The filter housing and all connection elements are designed so that pressure peaks – as they may occur e.g. in case of abrupt opening of large control valves due to the accelerated fluid quantity – can be securely absorbed.
Via the bleed screws (standard) and/or bleed valves – amending ordering code E – (7) the filter side to be maintained can be bled.
The sizes 0400-0630 / 0120 are equipped with mounting brackets. The standard pressure equalization line (10) serves to simplify the filling and bleeding in a filter element exchange.
By default, the filter is equipped with mechanical optical maintenance indicator (8). The electronic switching element (9) which has to be ordered separately is attached to the mechanical optical maintenance indicator (8) 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.

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 (cellulose) must not be used, filter elements with glass fiber filter material or wire mesh 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. |

| 1) | Servicing height for filter element exchange |
The max. operating pressure of the system must not exceed the max. admissible operating pressure of the filter (see type plate). In the assembly, depending upon the dimensions, you have to distinguish between floor mounting and wall mounting. 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. The filter covers may not be used as lifting points. Perfect filter function is only guaranteed when mounted with th filter cover vertically upward. The maintenance indicator must be arranged so it is easily viewed in operation. Filters with foot mount or wall mount should be securely using proper fasteners. Ensure that the system is assembled without tension stress. Remove the plastic plugs from the filter inlet and outlet. The optional electronic maintenance indicator is connected via the electronic switching element with one or two switching points, which is attached to the mechanical optical maintenance indicator and held by means of the locking ring.
Warning!
Assemble and disassemble only with depressurized system! Filter is under pressure! Remove the filter cover only if it is depressurized! Do not exchange the maintenance indicator while the filter is under pressure! Do not operate the switching lever and the pressure equalization valve during the filter element exchange. When disassembling the filter, it has to be ensured that the system is depressurized. If the flow direction is not considered during assembly, the filter element will be destroyed. Particles will enter the system and damage the downstream components.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.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 (See information on the indicator disc on the switch housing) The switch-over lever is on the filter side that is in operation. Close pressure equalization line.
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 corresponding replacement filter element is indicated on the name plate of the complete filter. It must correspond to the material number on the filter element. The switch-over lever is over the filter side that is in operation (See notice on the indicator disc of the switch housing). Open the pressure compensation at the ball valve. Switch the filter using the switch-over lever. Close the pressure compensation at the ball valve. Open the bleed screw or bleed valve at the decommissioned filter side in order to reduce the pressure. Via the drain screw, the oil on the dirt side can be drained. Remove the filter cover of the filter side that is not in operation. Remove the filter element from the spigot by rotating it slightly. Clean the filter components, if necessary. Check the seals for damage and replace them, if necessary. For suitable seal kits refer to chapter “Accessories”. 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. To fill the maintained filter side, open the pressure equalization line. 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. Ensure correct position of the switch-over lever end position. Close pressure equalization line.

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.
They 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.
The duplex filters and the electronic maintenance indicators described here can be used for the following explosive areas:

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.
