Working Principle

Speaking of air filters, everyone is familiar with it. In my impression, the air filter is the filter element inside to block dust, allowing clean air to enter the engine to participate in combustion. The most common air filter seen on trucks: inertial air filter. The filter element is one large and one small. The big one on the outside is called the “main filter element” and the smaller one on the inside is called the “safety filter element”.

The working mechanism of the inertial filter is: when the dust-containing air passes through the blade ring or the swirl tube, it will produce a vortex. Because of the inertia, the impurity particles will be thrown farther. In this way, when the particles rotate and collide with the filter housing, the speed will be reduced and deposited on the filter. The inertial pre-filter can filter out more than 80% of dust particles. The pre-filtered air is filtered by the second-stage paper filter element to ensure that the dust content of the air reaches an extremely low level.

The filtration efficiency of a qualified paper filter element can reach 99.5%. Although there are two paper filter elements inside and outside, it is the outer main filter element that performs the filtering function. The function of the safety filter inside is to block dust in case the main filter outside fails or other accidents, so as to protect the engine from being damaged by dust.
