When should I replace my air dryer cartridge?
Depending on how you drive the truck and how much air you consume, you might replace a cartridge like this every two or three years. More frequent replacement might be required if the compressor passes a lot of oil or the truck is used for vocational service.
What is the typical service life of an air dryer desiccant cartridge?
For Bendix standard desiccant cartridges, the recommended replacement interval for most long haul and delivery trucks is typically 24 months. Trucks that consume larger amounts of air – or are used in vocational service – should have cartridges replaced every 18 months.
What is an air dryer cartridge?

- Your Compressor Won’t Start.
- Your Compressor Won’t Stop.
- You Hear Odd Noises From the Compressor.

- Your System Blows Warm Air.
How long should an air dryer last?
For the standard trucking level which is typically pick up/delivery operations, Bendix suggests you replace your air dryer every 200,000 miles, or 24 months. In this application, you should also be checking for moisture in the dryer every 25,000 miles, or three months.
How often should an air dryer pop off?
Up to once a month for vehicles with high air demand or every three months for a typical line haul truck is recommended.
What is the purpose of an air dryer?
The basic function of the air dryer is to remove moisture from the air by cooling it with a refrigerant. Thus, the water vapor is condensed, and the air can be compressed. The result is dry compressed air, which can be used in compressed air equipment without causing any damage.
What is PuraGuard?
PuraGuard® oil coalescing from Bendix protects your investment by preserving the new advanced vehicle systems found on your vehicles. Yes, the cartridges are the same size from brand to brand, but critical differences exist in the engineering of the products.
What does an air dryer reservoir do?
The AD-IS® air dryer and reservoir system collects and removes air system contaminants in solid, liquid and vapor form before they enter the brake system. It provides clean, dry air to the components of the brake system which increases the life of the system and reduces maintenance costs.
What is the common cause of pneumatic dryer failure?
A failed drain is a leading cause of dryer failure. Introducing liquid into a dryer should be avoided. Now check filters to make sure they are not exhibiting excessive pressure drop. The filters should have some type of indicator for monitoring differential pressure.
What causes air dryer to keep popping off?
Check for air leaks in the line between the air governor and the drier pop off valve. This should be the center tap in the governor. if it is an ad-9 drier and it leaks through the purge valve after its initial main purge and doesn’t stop till it is back on the build cycle check the check valve in the discharge port.
What are three types of air dryers?

Why did my air dryer stop working?
If your coils are dirty, your air dryer isn’t getting proper air flow. The dirty lint blocks and traps the air. Time to clean! Use a soft cloth or brush to clean dirt from the refrigeration condenser coil to allow free passage of air.
How do you size an air dryer?
To figure out the right-sized dryer, divide the total flow by the total correction factor: 200 cfm / 0.861= 232 cfm (at standard conditions). Now, you can look at the dryers’ stated capacity on the dryer literature (excerpt shown below) and see which one will dry 232 cfm effectively.
What is dew point of air dryer?
Systems with refrigerant dryers pass the compressed air through a cooled heat exchanger, causing water to condense out of the air stream. These systems typically produce air with a dew point no lower than 5°C (41°F).
