How Many Filters Does a Semi-Truck Have?

How Many Filters Does a Semi-Truck Have?

Clean oil and air are crucial for the optimal performance of a semi-truck. Each automobile has different tools to remove contaminants from the air and oil. These parts are called filters that perform the function of filtration.

How Many Filters Does a Semi-Truck Have? Semi-trucks have two air filters and two oil filters. Air filters remove pollutants from the air, while oil filters make the engine oil clean. Worn-out filters can cause damage to the motor and decrease fuel economy. Change the air filter every 10000 miles and the oil filter after 10000 to 20000 miles.

The engine is the main component of a truck or vehicle that generates power by burning fuel and air. All its parts must be functional for the optimal performance of a truck.

Any defect in any part of the engine will cause the vehicle to get damaged. All parts of the semi work in coherence, and defects in one part will affect the performance of other parts.

What do the filters do in a semi-truck?

Semi-trucks require clean engine fuel and other lubricants to function properly. Filters are essential parts of every vehicle. Each vehicle needs air, oil, and fuel to run the wheels. The purity of all these necessities is crucial for smoothly running a truck.

They help in blocking all the impurities and hinder them from reaching different parts of the truck. Air is filled with different pollutants and particles. The oils and fuels are also loaded with minute particles.

These fine particles can clog different lines and have a bad impact on the performance of the engine. So all vehicles have them at different locations to block various impurities. The type and number of filters vary greatly in all vehicles.

Number of filters in a semi-truck

The number of filters in semi-trucks depends upon the size and the manufacturer. The semi-trucks have two air filter that is located at different locations. The engine air filter is present in the engine. While the cabin air filter is present in the hood of the truck.

The number of oil filters in a semi-truck is two, one is a primary, and the other is a secondary filter. One is located beside the suction flow lines, and the other is located between the suction pump and the oil injector. They ensure proper filtration of oil in the engine.

Types of filters in the semi-truck   

They are of different types depending upon their use. But semi-trucks usually have two types of filters. They all hinder dirt and filth from going to different areas of the truck.

Air filters

They remove dirt and debris from the air that is entering the vehicle.

First is an engine air filter that removes all the pollutant and dirt particles from the air that is required for combustion. The diesel engine requires an air and fuel mixture for combustion to generate power.

That’s why clean air is essential for producing energy to drive the truck. The engine air filter act as a barrier to all these pollutants, and clean air is delivered to the combustion chamber.

The dirt and pollutant present in the air is also harmful to the drivers. That is why cabin air filters are installed to remove all the dust and debris from the air. They remove all the dirt and other solid particles from the air and deliver it to the cabin.

Oil filters

The oil is used in the engine as a lubricating agent to lubricate all the parts. It is essential to reduce friction between parts of the engine. Oil full of dirt and debris can cause the engine to clog at different sites.

It can reduce the efficiency of the power-generating source. They speed up the normal wear and tear in the engine of semi-trucks.

It helps to deliver clean oil to the engine. There are two oil filters: one removes larger particles from the lubricant, and the other removes fine particles from the oil. Both of them ensure pure and clean oil lubricates the engine parts.

Do wear-out filters affect the performance of a semi-truck?

The filters in the engine remove the contaminant dirt and large objects from the air and oil. Both should be functional to act as a barrier against all these things.

Over prolonged use, they become clogged with dirt and debris. The accumulation of contaminants will hinder them from doing their job.

A clogged filter cannot remove all the dirt and solid object from the air and oil. Dirty air and oil can affect the performance of the engine. The presence of small objects in the oil can increase friction between engine bearings.

They can get damaged due to increased friction between them. Damage bearing will not be able to deliver the required oil pressure in the engine.

The combustion chamber will burn a fuel-rich mixture that causes the engine to make noises. The engine will not be able to deliver enough power to the wheels.

They also have a bad impact on the fuel economy of the trucks. Engine deprived of fresh air will burn more fuel than usual to run the vehicle. That’s why it is essential to check them regularly to keep them clean and functional.

How often to change air filters in semi-trucks?

It is essential to replace them at regular intervals to improve the engine performance. On average, semi-truck air filters last for up to 10000 to 20000 miles.

If you are driving the truck in a sandy or rocky area, it is better to replace them more often. In case of driving distance of a few kilometers, change them every 2 to 3 years.

You can visually inspect it to know about its condition. A worn-out filter is filled with dirt debris and another pollutant.

It appears black and filled with contaminants. A fresh filter quickly absorbs all the filth from the air. Do not try to reuse a clogged filer by washing them. It can cause more damage to them.

How often to replace oil filters in semi-trucks?

A faulty oil filter can also create great problems in the normal functioning of semi-trucks. It is better to replace it with a new one for smoothly running the truck.

It is advised to change the oil filter every 10000 to 20000 miles in semi-trucks. You can also check the manufacturer’s manual to get information about the life span of these filters.

It is better to change the engine oil along with changing the filter.

Do not use the old oil filter, as it is difficult to service a clogged worn-out filter. You can consult any professional about the condition of the filters before changing them. Different manufacturing companies offer services to replace the different parts of the truck.
