The function of the air filter is to filter the gas.

1. The air filter consists of a filter element and a housing. Its working requirement is that it can undertake high-efficiency air filtration, do not increase too much resistance for air flow, and can work continuously for a long time. It is also used in the hydraulic system of hydraulic machinery to varying degrees. It is mainly used to adjust the internal and external pressure difference of the oil tank of the hydraulic system.

2. What happens when the air filter is blocked? Make a dull roar; When the oil supply increases, the speed increases slowly. This is because the air intake is insufficient and the deflagration pressure of the working stroke is insufficient, so that the speed increases slowly; Inability to work, etc.

3. Precautions for the use of air filter: the oil level in the oil pool should be moderate. Because the oil level is too low, the oil quantity is insufficient, and the filtration effect is poor; The oil level is too high and there is too much oil, which is easy to be sucked into the cylinder for combustion. Clean the oil pan and change the oil regularly. Regularly clean the dust on the filter screen with diesel or gasoline.
