• Material: The Rexroth filter element is made of stainless steel, which has good corrosion resistance and mechanical strength, ensuring the long-term stable operation of the filter element.
• Form: The form of the filter element is a folding filter element, which can provide a larger filtering area while maintaining a smaller volume, suitable for various filters.
• Scope of application: Rexroth filter cartridges are suitable for filtering impurities in oil, especially for efficient filtration of fire-resistant fuels. Its working temperature range is 10 ℃, and the maximum working pressure difference can reach 10MPa.
• Flow direction: Rexroth filters have a flow direction from the outside to the inside, allowing for improved filtration efficiency and reduced possibility of filter blockage.
• Zinc-free components: All of Rexroth's first batch filter cartridges are composed of zinc free components, which are particularly suitable for the use of aqueous liquids (HFA/HFC) and synthetic oils. Zinc free components can prevent the formation of zinc soap, thereby avoiding premature "filter clogging" and greatly extending the service life of the filter cartridges.

The Rexroth filter element models are identified by letters that represent the type and purpose of the filter element, such as P, G, A, B, C, D, and more. Depending on the user's needs, they can select the suitable filter element from a variety of models.

The P series filter cartridge is designed for household water treatment, with different models such as P114, P365, and P389. These cartridges feature various characteristics, such as flow rates, purities, and durability. P114 and P365 are universal filter cartridges, which can remove residual chlorine, odors, and discoloration from water. However, they have limited ability to treat heavy metals. P389 is a rear filter element and is mainly used for pure water machines to filter out trace elements in water.

The G series filter cartridge is meant for commercial environments and hard water filtration. Commonly used models include G107, G177, and G256. G107 and G177 are descaling types and can effectively remove scale and some metal ions. Suitable for places that require hard water, such as dishwashers, washing machines, and more. G256, on the other hand, is used as a post filter element for water purification equipment, removing residual chlorine, odor, and providing sterilization.

The A, B, C, and D series of filter cartridges are divided according to different treatment purposes. The A series consists of activated carbon filter cartridges that can remove odors and residual chlorine from water. It is suitable for households and small commercial places. B series cartridges are ceramic filter elements and can remove bacteria and particles, making them ideal for drinking water treatment. The softening filter element in the C series can remove heavy metals such as calcium and magnesium, making it ideal for softening treatment of drinking, industrial, and commercial water. The D series is a reverse osmosis membrane filter and can remove various ions and heavy metals from water, making it the core filter for various purification equipment.

In conclusion, the letters on the Rexroth filter element models represent its type and purpose. Users can select the appropriate filter element, depending on their needs, and choose from different models based on their water quality situation to ensure the safety and cleanliness of their drinking water.
