How to replace the air filter element:

When using an air filter element, it is usually necessary to change the oil twice before replacing the filter element. If it is not replaced in time, a lot of dust will be adsorbed on the equipment, which will affect the operation of the engine.
When replacing this equipment, you must first turn off the system power and the valves before and after the precision filter; then open the drain port to drain the water in the filter; open the upper head, and pull out the precision filter element to flush the filter. After the cylinder wall, install the filter element, then seal the upper head and the drain port, and open the valve before and after the filter.
After the replacement of the filter element is completed, attention must be paid to ensure its own service life. To ensure its life, the oil must first be managed correctly, because the service life is not only limited by the solid particles deposited in the fine separation layer, but also increases the pressure difference. Under normal circumstances, replacing the equipment on time can ensure that the dirt entering the oil circulation loop is restricted, thereby prolonging its life. Of course, the selection of oil is also very important, because the use of oils that have been identified as having anti-aging and water-sensitive properties can ensure the normal operation of the equipment.
