The Bosch Rexroth 46.10 Z10-S00-0-M (R928025387) is a CELLUDISC filter element designed for the microfiltration of hydraulic and lubricating oils, particularly suitable for bypass filter applications. It excels in scenarios where high oil cleanliness is essential, such as filling filtration, supporting filtration in bypass systems, and flushing of hydraulics and lubrication systems. The performance of this filter element is characterized by its exceptional retention rate, substantial dirt holding capacity, and minimal pressure loss. Constructed from individual cells in a disc format, each cell comprises two ultrasonically welded discs with spacers at the edges to prevent contact between cells and ensure optimal filtration. The filter material itself is made from compressed and impregnated cellulose fibers supplemented with auxiliary materials to enhance the filtration process. The design facilitates filtration from the outside to the inside of the element. Additionally, this model features a zinc-free construction which prevents zinc soap formation when used with water-containing fluids (HFA/HFC) and synthetic oils. This attribute is particularly beneficial as it avoids early blockage of the filter element thereby extending its service life. It is also compatible with rapidly biodegradable hydraulic oils often required by manufacturers of construction and agricultural machinery. The Bosch Rexroth 46.10 Z10-S00-0-M achieves high oil cleanliness levels in accordance with ISO standards due to its defined retention capacity. Its non-reusable nature stems from its depth filtration effect which ensures that once contaminants are captured they remain within the filter media, securing protection for sensitive machine components against contamination. Its modular setup consists of interchangeable cells supported by a one-part design support tube, with a metal-free version available upon request. The auxiliary filter material supports the overall filtration process while ensuring high dirt holding capacity through deep filtration capabilities.

CELLUDISC filter elements are used for the micro filtration of hydraulic and lubricating oil, preferably as bypass filter.

Rexroth depth filter elements CELLUDISC serve the microfiltration of fluids in which very high oil cleanliness is required.

Typical applications are filling filtration, supporting filtration in the bypass and flushing of hydraulics and lubricating oil systems.

The main filter variables, such as retention rate, dirt holding capacity and pressure loss are determined by the filter elements and the filter media used in them.

Main flow filters are supported by the high retention rate by means of amending filtration in the bypass (multipass).

A high retention rate is already achieved in a single run (singlepass), e. g. in filling applications.

The filter element consists of 16 individual cells in the form of a disc, whereas every cell consists of two ultrasonic-welded discs. At the edges of the relevant discs, there are spacers preventing contact between the cells and ensuring perfect filtration.

The filter material consists of compressed and impregnated cellulose fibers which are provided with auxiliary filter materials in order to support the filtration process. Filtration is effected from the outside to the inside.

Two seal rings are provided between the filter element and the filter housing as a sealing.

Zinc-free filter element construction

All filter elements of the Rexroth preferred program are made of zinc-free components thus preventing the formation of zinc-soap, in particular if water-containing fluids (HFA/HFC) and synthetic oils are used. Moreover, many manufacturers of construction and agricultural machinery stipulate the use of zinc-free machine elements for rapidly bio-degradable hydraulic oils.

With regard to the aforementioned fluids, the use of zinc-free filter elements prevents early blocking of the filter element, thus considerably increasing the lifetime of the filter elements. Therefore, Rexroth filter elements can be used universally for hydraulic fluids and lubricants.

Cellulose fibers, Z… With the proper size selection and application, the filter medium achieves a high degree of cleanliness for hydraulic fluids and lubricants. Due to its defined retention capacity (ISO 16889), it offers highly effective protection for machine and system components which are sensitive to contamination. The filter material is composed of compressed and impregnated cellulose fibers, which are provided with filter auxiliary materials to support the filtration process. Absolute filtration/defined retention capacity according to ISO 16889 High dirt holding capacity due to pronounced depth filtration, with material density increasing with depth Non-reusable filter (not cleanable due to the depth filtration effect) Attainable oil cleanliness classes according to ISO 4406 up to 12/9/7.

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.

For applications outside these parameters, please consult us!

Filter variables

Filter rating and attainable oil cleanliness

The main goal when using industrial filters is not only the direct protection of machine components but to attain the required oil cleanliness.

Oil cleanliness is defined on the basis of oil cleanliness classes which classify how the amount of particles of the existing contamination is distributed in the operating liquid.

Filtration performance

Filtration ratio ßx(c) (ß value)

The retention capacity of hydraulic filters with regard to the contamination in a hydraulic system is characterized by the filtration ratio βx(c). This variable is therefore the most important performance characteristic of a hydraulic filter. It is measured in the multipass test, and is the average value of the specified initial and final pressure differential according to ISO 16889 using ISOMTD test dust.

The filtration ratio βx(c) is defined as the ratio of the particle count of the respective particle size on both sides of the filter.

Dirt holding capacity

It is also measured using the multipass test and determines the amount of test dust ISOMTD which is fed to the filter medium until a certain pressure differential increase has been reached.

Pressure loss (also pressure differential or delta p)

The pressure loss of the filter element is the relevant characteristic value for the determination of the filter size. The pressure loss with a clean filter element is recommended by the filter manufacturer or defined by the system manufacturer. This characteristic value depends on many factors. Mainly: the rating of the filter medium, its geometry and arrangement in the filter element, the filter area, the operating viscosity of the fluid and the flow.

The term “delta p” is often also expressed with the symbol “Δp”.

When dimensioning the filter, an initial pressure loss is determined which must not be exceeded by the new filter element state on the basis of the aforementioned conditions.

The following diagram shows the press loss behavior.

When has the filter element to be replaced or cleaned?

As soon as the dynamic pressure or the pressure differential set at the maintenance indicator is reached, the red push button of the optical-mechanical maintenance indicator pops out. Existing electronic maintenance indicators also give an electrical signal. In this case, the filter element must be replaced or cleaned.

Filter elements should be replaced or cleaned after max. 6 months.

Note:

If the maintenance indicator signal is ignored, the increasing pressure differential may damage the filter element causing it to collapse

Filter element exchange

For single filters: Switch off the system and discharge the filter on the pressure side. For installed duplex switch filters: refer to the relevant maintenance instructions according to the data sheet.

Rexroth filter elements are tested and quality-monitored according to different ISO test standards:
