Hydraulic oil tank breathing air filter EF3-40 EF2-32 EF-70 for generator canopy

The hydraulic air filter is composed of two parts: an air filter and a refueling filter. It not only prevents particulate pollutants from entering the system through the fuel tank breathing port, but also prevents particulate pollutants from being mixed during refueling. Using copper-based powder metallurgy sintered filter, compared with non-metallic filter material, it has the characteristics of stable filtration accuracy, high strength, strong plasticity, convenient disassembly and washing, an

The hydraulic Air Filter is composed of two parts: an air filter and a refueling filter. It not only prevents particulate pollutants from entering the system through the fuel tank breathing port, but also prevents particulate pollutants from being mixed during refueling. Using copper-based powder metallurgy sintered filter, compared with non-metallic filter material, it has the characteristics of stable filtration accuracy, high strength, strong plasticity, convenient disassembly and washing, and can withstand thermal stress and impact and normal operation under high temperature. Widely used in hydraulic system tanks


Principle and use

When the hydraulic system is working, the oil level in the oil tank rises or falls from time to time, discharges air from the inside to the outside when it rises, and sucks in air from the outside to the inside when it falls. In order to purify the oil in the fuel tank, an air filter is installed vertically on the cover of the fuel tank to filter the inhaled air; the same inlet air filter is the oil filling port, and the injected new working oil must be filtered before entering the oil tank , So as to filter out the dirt particles in the oil.


In the hydraulic system, purifying the working oil is a very important link. The air filter can keep the oil in the oil tank clean, prevent dirt particles from entering the oil tank from the outside, and prolong the working cycle and service life of the oil and components, thus ensuring the normal operation of the hydraulic system. In addition, when the hydraulic system is working, the air filter can maintain a balance between the pressure in the fuel tank and the atmospheric pressure to avoid cavitation in the pump.
