Working principle

When the hydraulic system is working, the oil level in the fuel tank rises or falls from time to time, the air is discharged from the inside to the outside when it rises, and the air is sucked in 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 fuel tank cover to filter the inhaled air. At the same time, the air filter is also an oil injection port, and the injected new working oil must be filtered before entering the oil tank, thereby filtering out the dirt particles in the oil.

In the hydraulic system, the purification of working oil is a very important link. The air filter can keep the oil in the fuel tank clean, which can prevent dirt particles from entering the fuel tank from the outside, thus ensuring the normal operation of the hydraulic system. In addition, when the hydraulic system is working, the air filter can maintain the balance between the pressure in the oil tank and the atmospheric pressure, so as to avoid the possible cavitation phenomenon of the pump.

Order selection: If you have the original model, please order according to the model. If there is no model, you can provide the threaded connection size, cap outer diameter size, product material and other accurate technical parameters, and support non-calibration.
