EF air filter hydraulic accessories

EF air filter is an instrument mainly used in hydraulic systems. With its unique structure and functional characteristics, EF air filter plays an important role in hydraulic systems, providing necessary protection and support for equipment in industrial production and other fields.

    Introduction to EF Air Filter

    EF air filter, also known as EF hydraulic air filter, is a new type of hydraulic accessory with multiple specifications, such as EF1-25, EF2-32, EF3-40, EF4-50, EF5-65, EF6-80, EF7-100, EF8-120, etc. Its structure consists of two parts: air filtration and refueling, which can prevent the mixing of particulate impurities during the refueling process, facilitate the purification of the oil, and simplify the structure of the fuel tank.

    Characteristics of EF air filter

    1. High filtration accuracy: EF air filters use copper based powder metallurgy sintered filter plates, which have the characteristics of stable filtration accuracy, high strength, strong plasticity, and easy disassembly and cleaning compared to non-metallic filters. In addition, it can withstand thermal stress and impact, and can work normally at high temperatures.
    2. Diverse functions: EF air filter is not only an air filtration device, but also an oil filling port. The newly injected working fluid must be filtered before entering the oil tank to remove dirt particles from the fluid.
    3. Pressure balance: When the hydraulic system is working, the EF air filter can maintain the pressure balance between the oil tank and atmospheric pressure to avoid possible cavitation of the pump.

    EF air filter usage scenarios

    EF air filters are mainly used in hydraulic systems to purify working oil, prevent impurities from entering the oil tank, extend the service life of oil and components, and maintain pressure balance inside and outside the oil tank. Specific usage scenarios include but are not limited to:

    1. Industrial production: Hydraulic systems are widely used in industrial fields such as steel, electricity, metallurgy, shipbuilding, textiles, electronics, chemicals, petroleum, mining, light industry, and machinery manufacturing. EF air filters play an important role as important hydraulic accessories in these fields.

    2. Transportation facilities: In the field of transportation facilities, such as the automotive industry, aerospace, etc., hydraulic systems also play an important role, and EF air filters provide necessary protection for hydraulic systems in these fields.

    3. Other fields: In addition, EF air filters are widely used in paper printing, food and medicine, casting spraying and other fields, providing a clean oil environment for equipment in these fields.
