Choosing the right components for a truck, such as the right air dryer cartridges, can make a big difference to both the vehicle's performance and its safety. It's an important aspect of ensuring your vehicles are winter-ready.

One of the components that needs replacement before winter is the cartridge. A new cartridge will prevent moisture from getting into the pneumatic system. Old or low-quality cartridges may lead to breakdowns, downtime and additional service costs. WABCO cartridges are always your best choice, for both truck and bus, no matter if they are used for long distances or for daily short-run deliveries.

Why choose WABCO?

Every genuine WABCO cartridge is engineered to keep your air brake system operating at optimum performance. It meets the same high standards we provide to commercial vehicle manufacturers, every day.

Our cartridges are extensively tested to ensure they deliver to your expectation. This includes ensuring that desiccants used in WABCO cartridges are tested for long-term stability under mechanical load and when in contact with oil-related products delivered by the engine compressor. At WABCO cartridges come with two types of high-quality, water absorbing agents:

  • Silica gel is recommended for all applications with a long-exchange interval (2 years maintenance interval). It exhibits better drying performance and stability over the gel’s lifetime when in contact with oil aerosols.
  • A molecular sieve is recommended for applications with lower air demand and shorter exchange intervals (a 1-year maintenance interval). The more water that’s absorbed, the weaker the molecular sieve agent gets – which explains the need to replace the cartridge in time.
