Abstract
A cartridge of an air dryer serves for cleaning compressed air to be used in compressed air supply systems of motor vehicles, especially trucks. The cartridge includes a housing, a pre-filter, a deposit chamber, a coalescing filter, a bypass conduit and a check valve. The deposit chamber is located downstream of the pre-filter. The deposit chamber is filled with a treating substance. The coalescing filter is arranged between the pre-filter and the deposit chamber. The bypass conduit is designed and arranged to bypass the coalescing filter and not to bypass the pre-filter. The check valve is arranged in the bypass conduit in a way that it opens during regeneration of the cartridge.
