Abstract
An air drier tower comprises a base part (2), a reservoir (1) attached thereto, and in the reservoir a cartridge (7) containing desiccant (8). The cartridge is composed of two halves (9,10) having circular walls extending into each other to form a winding air path through the desiccant. A spring (11) is arranged between the reservoir and the cartridge in order to exert a bias on one cartridge half and accordingly on the desiccant.
