The Castair I538HC2-S is the largest horizontal tank configuration in the 5HP three-phase Industrial Series — the C2 (larger) tank in the 38-series, with a factory-mounted magnetic starter. This is the unit for a three-phase shop where stored air volume is the priority: maximum receiver capacity with three-phase motor efficiency and the convenience of a factory-installed starter. If you are stepping up from a 33-series and need both more storage and three-phase efficiency, this is the top of the horizontal three-phase line in 5HP.
