The Rexroth filter cartridges have several key properties including their material, form, applicable range, and working temperature.

Material: The Rexroth filter cartridge is constructed from stainless steel which offers excellent corrosion resistance and mechanical strength, which helps to ensure the filter element can operate stably for a long period.

Form: Rexroth filter cartridges take the form of folding filter elements. This design allows a larger filtering area to be achieved while maintaining a smaller filter volume, making these cartridges a suitable option for a variety of filters.

Scope of Application: Rexroth filter cartridges are ideal for filtering impurities in oil, particularly for the efficient filtration of fire-resistant fuels. These cartridges function within a temperature range of 10℃ and can withstand a maximum working pressure difference of 10MPa.

Additionally, Rexroth filter designs consider the flow direction, which usually flows from the outside to the inside of the filter. This flow direction improves filtration efficiency and reduces the occurrence of filter blockage. The first batch of Rexroth filter cartridges is constructed with zinc-free components making them suitable for use in aqueous liquids like HFA/HFC and synthetic oils. The use of zinc-free components prevents the formation of zinc soap, which helps avoid premature "filter clogging" and extends the service life of the filter cartridges. The zinc-free design allows Rexroth filter cartridges to be used widely in common hydraulic oil and lubricant maintenance.

The Rexroth filter element model uses letters to represent the type and purpose of the filter element. These letters include P, G, A, B, C, D, etc. This makes it easy for users to choose a suitable filter element based on their needs.

The P series filter cartridge is designed for household use and can handle different types of water quality, including different flow rates, purities, and durability. Among the commonly used models are P114, P365, P389, and others. P114 and P365 are universal filter cartridges that can filter residual chlorine, odors, and discoloration in water. However, their ability to treat heavy metals is limited, so it is best to choose the appropriate filter cartridge based on the water quality in your area. P389 is mainly used as a rear filter element in pure water machines, which can filter out trace elements in water.

The G series filter cartridge is mainly used in commercial environments and can handle hard water filtration. The commonly used models include G107, G177, G256, etc. G107 and G177 are descaling types that can remove scale and some metal ions. They are suitable for places that require hard water, such as dishwashers and washing machines. G256 is mainly used as a post filter element for water purification equipment, which can remove residual chlorine, odor, and has a sterilizing effect.

The A, B, C, and D series filter cartridges are mainly divided into four series according to different treatment purposes. The A series is an activated carbon filter cartridge that can remove odors and residual chlorine in water, suitable for conventional household and small commercial places; The B series is a ceramic filter element that can remove bacteria and particles from water, suitable for the treatment of drinking water; The C series is a softening filter element that can remove heavy metals such as calcium and magnesium from water, suitable for softening treatment of drinking, industrial, and commercial water; The D series is a reverse osmosis membrane filter that can remove various ions and heavy metals from water, and is the core filter in various purification equipment.

To ensure the health and safety of water quality, users should choose the appropriate filter element according to their needs and select different models based on the water quality situation in their region.
