Key Information

The air dryer cartridge is a critical safety component. Its primary job is to protect the pneumatic system from corrosion, sludge buildup, and freezing in cold conditions.

The cartridge contains desiccant beads that absorb water vapor from the compressed air coming from the air compressor. As the system "cycles" (unloads), it purges the captured moisture out of the system.
