The Castair I533HC1 is a 5HP three-phase industrial air compressor in horizontal tank configuration, shipped without a factory-mounted starter. This is the three-phase counterpart to the I513HC1 — same industrial motor, same cast iron pump, same horizontal tank — without the starter assembly, for installations where the motor starter is already in place or will be sourced separately. Three-phase power means more efficient motor operation and smoother startup characteristics compared to single-phase.
