The hydraulic tank air filter EF8-120 is a core accessory designed for hydraulic system oil tanks. It is suitable for industrial scenarios such as power plants that have strict requirements on oil cleanliness. It adopts a dual filtering structure (air filtration + oil filling filtration), which can effectively prevent external particulate impurities from entering the oil tank, while simplifying the oil tank design and extending the service life of hydraulic oil and components. The air filter element is made of copper-based powder metallurgy sintered filter sheets, which has the characteristics of high temperature resistance, impact resistance, stable filtration accuracy, etc., and can work stably under high temperature and high pressure environments in power plants.

 

 

​Air filtration: When the oil level in the oil tank drops, filter the inhaled air to prevent dust and particles from entering the system.

​Oil filling filtration: When new oil is injected, the oil is purified through the built-in filter (oil filtration accuracy 125 μm) to avoid secondary pollution.

​Pressure balance and anti-cavitation: Maintain the pressure balance inside and outside the oil tank to avoid cavitation caused by negative pressure in the hydraulic pump and ensure stable operation of the system.

 

​High compatibility: Suitable for high-pressure oil tanks such as hydraulic systems and engineering machinery in power plants, supports customized anti-corrosion models, and is suitable for water-ethylene glycol media.

​Durability: The copper-based filter has high strength and can be repeatedly disassembled and washed, and can withstand frequent start-up and shutdown and thermal stress shocks in power plants.

​Easy maintenance: The modular design simplifies the replacement process, reduces downtime, and improves the operation and maintenance efficiency of power plants.

 

​Flow matching: It is recommended to select the air flow according to 1.5 times the displacement of the hydraulic pump to optimize the filtering performance.

​Installation requirements: It needs to be installed vertically on the oil tank cover to ensure the normal operation of the breathing and oil filling functions.

​Customization service: Supports customization of non-standard sizes, materials and filtration accuracy to meet the special working conditions of power plants.
