***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth 50LE0150-PWR10A00-V22-M-R4 (R928050822) is an advanced inline hydraulic filter designed to ensure the purity of fluids and lubricating oils in hydraulic systems by removing solid contaminants. This particular model is engineered for direct installation into pressure lines, providing protection for downstream components. The filter comprises a robust filter head, a screw-in filter bowl, and a high-quality filter element that includes a mechanical-visual maintenance indicator for monitoring its condition. The LEN inline filter features a built-in bypass valve for filters with low-pressure-differential-stable filter elements, indicated by the code letter 'A'. This valve comes pre-assembled as standard, safeguarding the system against potential pressure peaks that could occur with sudden operations of control valves. To mitigate vibrations and secure the filter element during maintenance, an installed spring mechanism is utilized. Fluid enters through the inlet, passes through the filter element where impurities are trapped, and then exits via the outlet to rejoin the hydraulic circuit in a purified state. The housing and connection components are durably constructed to withstand significant pressure fluctuations. Additionally, standard models from this size include a drain screw for easy maintenance. The 50LE0150-PWR10A00-V22-M-R4 comes equipped with a mechanical-visual maintenance indicator by default. For enhanced functionality, an electronic switching element can be ordered separately and integrated with the indicator using a locking ring; this allows for connection via mating connector or cable and can feature one or two switching points. This LEN series inline filter offers exceptional filtration capabilities across various flow rates and operating pressures while maintaining high dirt holding capacity and excellent collapse resistance of its elements. It operates effectively over a wide temperature range and accommodates multiple connection sizes from G1/4 up to G1 1/2. Optional features include various electrical switching elements for tailored monitoring solutions and an integrated bypass valve within the housing for additional system security.

Inline filters are used in hydraulic systems for separating solid materials from fluids and lubricating oils.

The 50LE(N) inline filter is suitable for direct installation into pressure lines. It is installed upstream components to be protected.

It basically consists of filter head (1), a screwable filter bowl (2), 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 an assembled bypass valve (5) by default.

The installed spring (6) prevents possible vibrations of the filter element (3). During disassembly, the contact pressure of the spring (6) holds the filter element in the filter bowl (2).

Via the inlet, the 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 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 (7).

By default, the filter is equipped with mechanical/visual maintenance indicator (4). The electronic switching element (8) 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 or via a cable connection.

50LEN0160

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.

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. 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.

 

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

 

Notice:

There is no bleeding provided at the filter.

 

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

Screw off the filter bowl.

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. 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.

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

Commission the system.

 

NOTES!

Assembly and disassembly only with depressurized system!

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!

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

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.
