PAF Breather Filter Series
product description
PAF series products are suitable for use in construction machinery, vehicles, mobile machinery and hydraulic system oil tanks that require pressure. This product consists of four parts: air filter, air intake check valve, exhaust check valve, and refueling filter, which simplifies the structure of the fuel tank and is conducive to oil purification. When the hydraulic system is working, the liquid level in the tank rises or falls from time to time. When it falls, the PAF product inhales air, which automatically enters the air intake check valve [2] through the filter screen [3] and enters the fuel tank. At this time, the pressure in the tank is less than the predetermined pressure. The exhaust check valve [] is in a closed state, which can maintain the predetermined pressure in the tank, improve the self-priming ability of the oil pump, maintain the stability of the liquid in the tank, and avoid possible problems such as vacuuming of the pump due to oscillation or turmoil of the liquid in the tank. . When the working cycle returns to the oil tank, the liquid level rises, and the temperature of the working oil also increases, generating oil mist gas and increasing the pressure in the oil tank: when the pressure in the oil tank is greater than the predetermined pressure, the exhaust check valve 1] Automatically open the exhaust to the outside. The exhaust check valve [] will not automatically close until the pressure inside the box equals the predetermined pressure. This back-and-forth circulation can not only protect the normal operation of the hydraulic system, but also extend the working cycle and service life of the oil and components.
