ABSTRACT:
An air drying cartridge for use in an air drying system is disclosed. The air drying cartridge comprises a telescoping casing resiliently self adjustable in height which has an inner cylindrical apertured wall and an outer cylindrical apertured wall. The inner apertured wall has a facing surface, an upper end and a lower end. The outer apertured wall has a facing surface, an upper end and a lower end. The facing surface of the inner apertured wall is disposed to face the facing surface of the outer apertured wall thereby defining an opening therebetween. The air drying cartridge also includes a porous filter liner, a pair of sealing caps and a moisture absorbing material for extracting moisture from air flowing through the air drying cartridge. The porous filter liner is situated adjacent to each of the facing surfaces within the opening. One of the pair of sealing caps affixes to the upper ends of the apertured walls and another affixes to the lower ends of the apertured walls. The moisture absorbing material fills the opening between the filter liners and sealed therein between the sealing caps. The telescoping casing resiliently withstands compressive forces that would collapse, rupture or otherwise distort prior art dryer cartridges. The desiccant cartridge 30 exsiccates air more reliably and efficiently than prior art desiccant devices.
