Cleaning sequence

First, remove the main filter element, block both ends of the filter element with a clean cloth or rubber plug, brush the surface of the filter element along the crease direction with a soft brush, and gently tap the end surface of the filter element to make the dust fall off. You can use 0.2-0.3MPa compressed air or leather tiger to blow air from the inside to the outside of the filter element to blow away the dust adhering to the outer surface of the filter element. It is forbidden to use liquid cleaning during cleaning to prevent the filter element from adhering to dust and causing the filter element to block.

Secondly, check whether the main filter element is damaged. Whether the upper and lower end surfaces are warped and uneven; check whether the rubber sealing ring of the main filter element is damaged; check whether there is dust inside the main filter element. If the above problems exist, the main filter element should be replaced immediately.

Finally, use a bright flashlight to check whether the filter element is damaged. Do not remove the safety filter element during inspection. If the safety filter element is damaged, replace it immediately. In the process of cleaning the housing of the air cleaner, wipe the inner wall of the housing with a clean cloth and check whether the dust exhaust valve can discharge dust normally.

If the air filter is cleaned frequently, the filtering capacity of the filter element will not be fully utilized, which will not only increase the amount of dust entering the engine, cause abnormal wear and tear of the engine, but also cause early damage to the filter element. Each time the filter element is cleaned, its dust holding capacity will be reduced by 20%-40%. As the number of cleaning increases, the dust holding capacity of the filter element will gradually decrease. When the filter element is cleaned for about 6 times, its dust holding capacity is basically lost. At this time, the filter element should be replaced immediately.
