SUMMARY:  Pall Filter Elements

Due to extremely high demand, please call 888-651-5712 for availability

The filter element is the central component of a filter for industrial and mobile area. The actual filtration process takes part in the filter element. The main filter variables, such as retention capacity, dirt holding capacity and pressure loss are determined by the filter elements and the filter media used in them. Rexroth filter elements are used for the filtration of hydraulic fluids in the hydraulic system as well as for the filtration of lubricants, industrial fluids and gases.

 

Filter elements consist of a combination of star-like pleated filter media (3) which are laid around a perforated support tube (2). Support tube and filter element mat are glued to both end disks (1). Seal rings are provided between the filter element and the filter housing as a sealing.

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!

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 pushbutton of the mechanical/visual maintenance indicator pops out. If an electronic switching element is provided, an electric signal will moreover sound. In this case, the filter element must be replaced or cleaned.

If the filter does not have a maintenance indicator, we recommend exchanging or cleaning filter elements after a maximum of six months.

 

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 filter type.

Detailed instructions with regard to the filter element exchange can be found on the data sheet of the relevant filter series.

 

Warning:

Filters are containers under pressure. Before opening the filter housing, check whether the system pressure in the filter has been decreased to ambient pressure. Only then may the filter housing be opened for maintenance.

 

Notice:

Due to the high viscosity, the pre-set signal value of the visual maintenance indicator may be exceeded during cold start. After the operating temperature has been reached, the mechanical/visual indicator can be acknowledged manually. The electrical signal will go out after the operating temperature has been reached. If the maintenance indicator signal is ignored, the disproportionately increasing pressure differential may damage the filter element causing it to collapse. 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.

G…

Cleaning or replacement

Before cleaning a G... element, the filter element has to be dismantled first and then checked whether it makes sense to clean the element. For example, if the cloth contains many fibrous substances and consists of a material finer than G40, effective and complete cleaning is not possible in many cases. Filter mesh which has visible defects due to frequent cleaning must be replaced. In general, the following applies: The finer the cloth, the thinner the wire. Therefore, especially fine mesh must be cleaned gently to protect the material. Cracks in the folds of the wire mesh and the metal fiber fleece are to be avoided. Otherwise, the filter capacity will be insufficient.

Cleaning frequency

Experience has shown that filter elements made of G10, G25 and G40 can be cleaned up to ten times.

Filter mesh > 60 μm can usually be cleaned more than ten times. Reusability, however, very much depends on the type of contamination as well as on pressurisation (final Δp before dismantling the filter element). For maximum reusability, we therefore recommend exchanging in particular the fine mesh at a final Δp of 2.2 bar at the latest. Due to the given reasons, the aforementioned values must be regarded as reference values for which we do not assume any liability.

Manual and simple cleaning method for filter elements made of wire mesh

Procedure

Wire mesh G10, G25, G40

Wire mesh G60 and larger

Chemical pre-cleaning

Let the filter element drain for approx. 1 hour after disassembly. Bathe in solvent afterwards.

Mechanical pre-cleaning

Remove rough dirt with a brush or scrubber. Do not use hard or pointed objects which could damage the filter medium.

Mechanical/chemical main cleaning

Put pre-cleaned element in an ultrasonic bath with special solvent. Clean the element in the ultrasonic bath until any visible contamination is removed.

Evaporate with hot washing solution (water with corrosion protection agent)

Test

Visually check the material for damage. Replace the filter element if you identify obvious damage.

Preservation

After drying, you must spray the cleaned element with preservative agents and store it sealed against dust in a plastic foil.

Automated cleaning method for filter elements made of wire mesh

Procedure

Wire mesh G10 ... G800

Chemical pre-cleaning

Let the filter element drain for approx. 1 hour after disassembly. Bathe in solvent afterwards.

Mechanical/chemical main cleaning

By means of special cleaning systems for filter elements. Most of these systems are provided with a fully automated and combined cleaning mechanism including ultrasound as well as mechanical and chemical cleaning processes. This allows for best possible cleaning results with gentle cleaning processes.

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. These are recommended values of the filter manufacturer or specifications by the filter user. 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 complete filter with filter element, 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 size design of a Rexroth filter element and new complete filter by means of initial Δp or pressure loss may be comfortably completed using our online design software “BOSCH REXROTH FILTERSELECT”.

The following diagram shows the typical press loss behavior of filter elements with different material fineness at different flows for a viscosity of 30 mm2/s.

The diagram shows the typical pressure loss behaviour of filter elements with different filter media at different flow rates.

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

 

Filtration performance test (multipass test): ISO 16889:2008-06

Δp (pressure loss) characteristic curves: ISO 3968:2001-12

Compatibility with hydraulic fluid: ISO 2943:1998-11

Collapse pressure test: ISO 2941:2009-04

 

The development, manufacture and assembly of Rexroth industrial filters and Rexroth filter elements is carried out within the framework of a certified quality management system in accordance with ISO 9001:2000.

Rexroth filter elements for installation in Pall filter housings are exchangeable with regard to their dimensions with the aforementioned competitive filter elements.

They comply with the state-of-the-art in technology and are developed and tested according to specific test procedures such as ISO 16889 (filtration performance test), ISO 2941 (collapse pressure) and ISO 3968 (pressure loss).

The Rexroth filter elements recommended by us are exclusively intended for intended applications. They must be maintained regularly and replaced, if necessary.

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.
