Abstract
An air suspension system includes an air suspension, a compressor, a dryer apparatus, and so forth. The dryer apparatus includes a dryer case, an inner cylinder, a first inlet port, a first outlet port, a first desiccant, an outer cylinder, a second inlet port, a second outlet port, a second other-end side filter, a second desiccant, and so forth. The first desiccant comprises a molecular sieve, for example, which exhibits high water adsorption performance at high temperature. On the other hand, the second desiccant comprises silica gel, for example, which exhibits high water adsorption performance at low temperature.
