Air filters play a crucial role in self loading concrete mixer trucks (as well as all vehicles driven by internal combustion engines). Its main functions can be summarized as follows. More details about self loading mixer trucks are available on selfloadingmixertruck.com.

Filtering air
The main function of an air filter is to filter impurities such as dust, sand, pollen, and other small particles from the air entering the engine combustion chamber. If these impurities enter the engine directly, the will accelerate the wear of cylinders, piston rings, and pistons, and may even cause cylinder pulling, seriously affecting the performance and lifespan of the engine.

Protecting the engine
By filtering the air, the air filter effectively reduces the amount of pollutants entering the engine interior, thereby protecting key components of the engine from wear and corrosion. This is crucial for maintaining the good operating condition of the engine and extending its service life.

Improving fuel efficiency
Clean air helps fuel burn more fully, thereby increasing fuel efficiency. If the air filter is clogged or the filtering effect is poor, the amount of air entering the engine will decrease, resulting in insufficient fuel combustion, increased fuel consumption, and reduced engine power.

Reduce emission
A good air filter can ensure that the engine runs at its best, thereby reducing the emission of harmful substances. This is of great significance for environmental protection and compliance with emission regulations.

Improving engine performance
A clean air filter ensures that the engine receives sufficient clean air to maintain its optimal performance. This includes improving acceleration performance, reducing noise and vibration, etc.

Therefore, regular inspection and replacement of air filters is an important task in the maintenance of concrete mixer trucks. Drivers and maintenance personnel should closely monitor the condition of the air filter and determine the replacement cycle based on the manufacturer’s recommendations and the actual usage of the vehicle. In harsh working environments, such as construction sites with high dust concentrations or sandy areas, it may be necessary to inspect and replace air filters more frequently to ensure the normal operation of the engine.
