An air cleaner is a component in the vehicle’s air intake system that filters out dust, dirt, and other particles from the air before it enters the engine. This is crucial for protecting the engine’s internal components from wear and preventing contaminants from affecting performance. A clean air supply also helps optimize fuel consumption and reduce emissions.

There are several types of air cleaners, including dry air filters, oil-bath filters, and pre-filters. Dry air filters use a paper or fiber material to capture particles, while oil-bath filters use oil to trap dust and dirt. Pre-filters are usually placed before the main filter and catch larger particles to extend the life of the primary filter. Many modern machines use multi-stage filtration with both pre-filters and main filters for optimal air purification.

Signs that an air cleaner may need replacement or cleaning include reduced engine power, increased fuel consumption, and difficulty starting the machine. If you notice a loss of performance or the engine seems to “breathe” heavily, a clogged filter may be the cause. Regularly check the air cleaner and replace or clean it according to the manufacturer’s recommendations to prevent engine damage.
