4437838 ELEMENT For HITACHI ZX450 6WG1

The main function of air respirator filter in hydraulic oil tank is to prevent particles in hydraulic oil from entering the tank and protect the normal operation of hydraulic system. The working principle of air respirator filter for hydraulic oil tank is to prevent particles in hydraulic oil from entering the oil tank by filtering media such as cotton or oil screen. When the piston rod of the hydraulic cylinder extends, the hydraulic pump sends the hydraulic oil into the hydraulic cylinder, and when the piston rod retracts, the hydraulic oil returns to the hydraulic tank. In this process, the air in the oil tank is exhausted through the respirator, and the filter medium will intercept the particulate matter in the air to prevent it from entering the oil tank with the hydraulic oil.

Hydraulic air filter is composed of air filter and refueling filter, which can not only prevent particulate pollutants from invading the system through the breathing port of oil tank, but also prevent particulate pollutants from being mixed during refueling. Compared with non-metallic filter materials, copper-based powder metallurgy sintered filter has the characteristics of stable filtering accuracy, high strength, strong plasticity, convenient disassembly and washing, and can withstand thermal stress and impact and work normally at high temperature. Widely used in hydraulic system oil tank. ELEMENT air respirator filter is a kind of equipment used to filter particulate matter and harmful substances in the air, which is usually used in industrial, fire fighting, military and other fields to ensure the cleanliness and safety of breathing air.
