Air dryers are critical for a truck’s air system. They help the air system function properly, removing moisture from the air. In fact, they are responsible for keeping anti-lock brakes and other vehicle safety systems working properly. Despite its importance, it is often overlooked. Air dryer cartridges are a relatively new addition to the truck air system, but their importance cannot be underestimated. Read on to learn more about their function.
Air dryers are necessary for heavy-duty trucks. They remove moisture and other contaminants from compressed air and prevent them from freezing in the system. It also extends the life of air valves on trucks. Air dryers are also installed between the air compressor and the truck’s first or secondary air tanks.

How Does a Truck Air Dryer Work?
As more on-vehicle technologies utilize the truck air system, it is crucial to protect this system from contamination. A truck air dryer is designed to prevent solid, liquid, or aerosol contaminants from entering the air brake system. It has become a staple in truck air systems, and Bendix has sold over 10 million of these units. Here’s how they work:
An air dryer is plumbed into the vehicle’s air system and compressor, as well as the first and secondary tanks. Some systems feature a wet tank, while newer ones have a wet and dry tank. They are all top-hat-shaped, and are located on different parts of the vehicle. Some are located in the engine compartment, while others are hidden behind the cab. Regardless of location, air dryers are essential to the overall function of a truck’s air system.
An air dryer is a device that filters out contaminants and moisture from compressed air. These devices are typically mounted between the compressor and the first and secondary air tanks. An air dryer is also a great safety feature. Air dryers prevent water-based contaminants from freezing in the system. An air dryer can be very helpful when repairing a vehicle. Luckily, they are relatively quiet. If you are thinking about getting a truck air dryer, there are a few things you should know about this piece of equipment.
When Should I Replace My Air Dryer?
If you own a heavy truck, you probably want to know when to replace your air dryer. It should be replaced every 12 months, depending on usage. Trucks with heavy air usage, such as school buses and garbage trucks, should be checked for moisture every 25,000 miles. A video of replacing an air dryer can help you determine when to replace yours. Alternatively, you can contact Blaine Brothers to get a quote on air dryer replacement.
The frequency of air dryer replacement varies depending on the type of air compressor, the volume of air used, and the environment of the truck. Drivers should pay attention to the air in the truck’s service tanks. Excessive moisture or water mixed with oil can lead to premature air dryer replacement. To determine the proper service interval for your truck’s air dryer, reference the service data sheet for your particular brand.
How Do I Know If My Air Dryer is Bad?
A sagging wet tank on your truck is a sign that your air dryer isn’t functioning properly. A sudden increase in moisture in the wet tank could be a sign that the air dryer cartridge has failed. This is common, but it is also possible that your air system is too old and needs upgrading. There are ways to tell if your air dryer is bad, though.
If you see a sagging air gauge, check the compressor’s discharge valve to see if it’s clogged with oil. Oil will prevent the discharge line from working properly and cause the air system to be slow. If the oil is clogging the discharge line, consider replacing the air dryer altogether. You can easily check this by following these steps:
If the problem is the air compressor, the air suspension dryer assembly may be at fault. This component is responsible for protecting the entire air suspension system. If this part of the air system is failing, you should take the truck in for maintenance. YourMechanic technician will be able to diagnose the problem and fix it. YourMechanic technician will also inspect the other components in the suspension system.
What Happens When Air Dryer Goes Bad?
What Happens When an Air Dryer on A Truck Goes Bad? Several reasons can cause an air compressor to cycle. First, a clogged air discharge line may be the cause. This means that oil has backed up into the air system, clogging the discharge line and slowing down the entire system. Oil may also be passing through the air compressor.
If the truck has an air brake system, it might also develop excess moisture on the ground. The moisture is a sign of a problem with the air dryer or compressor. It can even scare people walking on the road. As a result, you should check the air dryer for leaks. If it does, you should call your mechanic immediately. During repair, you can avoid the hazard of a broken air brake system.
When the air dryer fails, it is critical to replace the cartridge as soon as possible. Large trucks, school buses, and heavy-duty vehicles should have their air dryer cartridges replaced every year or every 100,000 miles. Triple-haul and double-haul trucks, on the other hand, can go two years without replacing the cartridges. Heavy-duty trucks require regular maintenance and may be difficult to diagnose on your own. A failure of an air dryer may also result from leaks, clogs, and worn parts.
How Often Should a Air Dryer Pop Off?
The answer depends on the type of vehicle and the amount of use it receives. Large trucks and school buses should get new air dryer cartridges every 100,000 miles. In contrast, double-haul trucks and triple-haul trucks can go up to two years between air dryer cartridge replacements. Nevertheless, heavy trucks are a little different and need to be serviced by a qualified professional. Leaks, clogs, worn parts, and electrical issues can all cause air dryers to fail.
When you drive your vehicle, you’ll notice that the air dryer is often located directly beside the governor. The dryer’s job is to prevent oil and water from entering the air brake system. When they do, they destroy the desiccant material inside the air dryer. If you see oil coming out of the air dryer, it is most likely that the air compressor has a clogged air intake or return or is simply worn out.
How Do I Test My Air Dryer?
If your truck does not have an air dryer, you can check its condition using the Mitchell 1 TruckSeries truck repair software. This software contains comprehensive maintenance, component replacement, and operation and functional testing information. You can find the information you need by selecting the model from the software’s drop-down menu. You’ll then find information on how to test the dryer. You can also get service and testing procedures for the particular model.
To perform a test, you first need to open the drain valves for the reservoirs and the purge tanks. If you notice any moisture, the system is not functioning properly. If you detect moisture, drain the reservoirs and purge tanks. Then start the vehicle and slowly build system pressure to the governor cutout pressure. Once you have the proper pressure, you can operate the vehicle normally.
Do You Need Oil in Air Dryer?
Usually, trucks have a “standard” spin-on cartridge that is designed to remove water and some particles. Oil aerosols, however, do not pass through this type of cartridge. Therefore, it is vital to check the oil levels in your truck’s air dryer regularly. If the oil level is too high, it will cause the air dryer to run longer than it should. The oil can also build up in the media, resulting in higher fuel costs.
Another important function of air dryer cartridges in trucks is to keep moisture out of the air system. This air system is responsible for anti-lock brakes, and the dryer plays a major role in these features. The dryer removes liquid, oil, and aerosol contaminants from the air, preventing them from entering the air brake system. Air dryers have been used in trucks for over a century by Bendix, with over 10 million units being manufactured.
