The Bosch Rexroth 10TEN0250-G25A00-ML-M-R6 (R928044957) is a state-of-the-art tank mounted return line filter designed for seamless integration into hydraulic or lubrication systems. This filter unit is engineered to be affixed directly onto the tank, serving as an efficient solution for fluid purification during system operation or while being used as a filling or bypass filter. The assembly includes a robust filter head, bowl, and cover that house the high-quality filter element and a standard bypass valve. The Bosch Rexroth return line filter boasts a mechanical-visual maintenance indicator that signals when the filter element requires replacement due to contamination. For enhanced monitoring, an electronic maintenance indicator can be optionally installed; this requires an additional electronic switching element with one or two switching points, which is purchased separately. As hydraulic fluid enters the inlet during operation, it is directed through the external surface of the filter element towards the inside, ensuring thorough cleansing according to the selected filtration rating. Particulate matter is effectively captured within both the bowl and element. The purified fluid then exits through the outlet back into the tank system. This model also features an electronic switching element that easily attaches to the mechanical-visual indicator and secures with a locking ring. Additional functionalities are available for larger filters (NG series), including options such as breathing filters, surge protection, and return pipes of varying lengths. Users can refer to specific chapters in product documentation for further details on ordering codes and accessories. Constructed with special highly efficient media, this Bosch Rexroth filter excels in filtering very fine particles while offering an impressive dirt holding capacity over a wide pressure differential range. The elements are designed for high collapse resistance, ensuring longevity and reliability. Users may also opt for various electrical switching elements thanks to its modular design and even choose models equipped with mechanical optical maintenance indicators featuring memory functions. A measuring port can be included optionally for more precise monitoring needs.

The tank mounted return line filter is provided in the return line for direct attachment onto the tank of a hydraulic or lubrication system. It can also be used as filling or bypass filter. It basically consists of filter head (1), filter bowl (2), cover (3), filter element (4) as well as a bypass valve (5), by default.

Optionally, the filter is equipped with mechanical/visual maintenance indicator (6). The electronic maintenance indicator is connected via the electronic switching element (7) with 1 or 2 switching points (see p. 7), which has to be ordered separately.

During operation, the hydraulic fluid reaches the filter housing via the inlet; here, it flows through the filter element (5) from the outside to the inside and is cleaned according to the filter rating. The dirt particles filtered out settle in the filter bowl (3) and in the filter element (5). Via the outlet, the filtered hydraulic fluid enters the tank. In case of contamination, the necessary filter element exchange is displayed by the maintenance indicator (7).

The electronic switching element (7) is attached to the mechanical/visual maintenance indicator (6) and held by means of a locking ring.

Depending on the filter size, more additional functions (only for NG0040 ... 0100) are available - e.g. a breathing filter (8), surge protection (9) or return pipes (10) in different lengths – in this connection, also refer to the chapter “Ordering code Accessories”.

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.

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. More details see data sheet for filter elements.

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.

Switch off the system, discharge the filter on the pressure side.

Screw off the filter cover (NG0040-0100) and/or loosen the screws (from NG0160) and remove the filter cover upwards.

Notice:

Note that with lower ratings, it may take slightly longer to discharge the residual oil. If the filter element is removed before the residual oil has been discharged, contaminated oil may reach the clean side.

Remove the filter element including filter bowl. From frame size 0160, the filter bowls are equipped with removal brackets.

Remove the filter element from the spigot in the filter bowl by rotating it slightly; clean the filter components if necessary.

Check the seals at filter cover and filter bowl for damage and renew them, if necessary. For suitable seal kits refer to chapter “Ordering code Spare parts”.

Filter elements made of wire mesh can be cleaned. For detailed cleaning instructions refer to the data sheet for filter elements.

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.

Commissioning

Commission the system.

Notice:

There is no bleeding provided at the filter.

Assembly:

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

Before the assembly, the hole pattern of the tank must be compared to the dimensions from the "Dimensions" chapter.

As of a length of approx. 500 mm, drain pipes must be led in a bracket in order to avoid oscillations caused by the fluid flow in the tank. It is moreover to be ensured that in case of maintenance works, the filter bowl and the outlet pipe are pulled out of the filter head together.

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 and ON the tank.

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 electric 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. More details see data sheet “Maintenance indicator”.

Notices:

Assemble and disassemble only with depressurized system! For the filter element exchange refer to “Maintenance”. Tank is pressurized! Do not operate the switching lever during the filter element exchange. 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.
