Abstract

The air dryer cartridgehas a first connectorfor mating with a corresponding connector of a conventional air dryer system, and a second connectorfor mating with a corresponding connector of a newer-style air dryer system. When the cartridgeis installed on a conventional air dryer system, purge air valvingwithin the cartridge is deactivated causing the cartridge to act as a conventional air dryer cartridge. When the cartridgeis installed in a newer-style system, the purge air valvingwithin the cartridge is activated thus enabling the system to function as designed.
