How does FONHO Truck Air Dryer with Oil Separator (Coalescing Technology) Work for More Safety in Air Brake System?
Why is a truck air dryer necessary for an air brake system?
As we know air brake systems are usually used in heavy vehicles, such as trucks and buses, and other large vehicles. Since air compression is required in the air brake system, moisture and condensate may be introduced into the system, then the air brake system will be affected if the moisture is not removed. Under severe operating conditions, moisture can freeze, causing the brake to fail completely.
To prevent this from happening, air dryers are required. In addition to removing moisture, the air dryer can also remove any oil leaking from the air compressor, as well as aerosols that may enter through the air intake system. In short, the purpose is to filter out contaminants such as water, oil vapor, and aerosol to prevent freezing in winter and extends the life of the air valve.
How does the oil separator air dryer desiccant cartridge work?
Once entering the air dryer desiccant cartridge, the air first flows through the oil separator located between the inner and outer shells. The separator removes water in liquid form as well as oil and solid contaminants.
When the air leaves the oil separator with the remaining water vapor, it is further cooled and continues to flow upward between the outer shell and the inner shell. After reaching the top of the air dryer filter cartridge, the air flows in the reverse direction and enters the desiccant bed. Moisture is “absorbed” on the surface of the desiccant bed and then, the air that comes out from the exhaust is dry without any contaminants.
About Maintenance of spin on truck air dryer filter
Regular maintenance every 900 hours or 40,000 kilometers or 3 months will ensure that your air system remains in top working condition. Check the moisture in the air brake system by opening the drain valve. If moisture is present, the air dryer filter may need to be replaced.
