The Castair D7324HC2-S is a 15 HP duplex air compressor with two 7.5 HP pumps on a 240-gallon receiver tank, wired for three-phase service. This is the premium configuration in the Cast Air 15 HP duplex class -- maximum capacity, maximum storage, and three-phase efficiency in a single package. For a high-production facility with three-phase service that needs the most capable compressor in the 15 HP duplex range, this is the specification to consider.
Top of the 15 HP Duplex Range
The combination of 7.5 HP three-phase pumps and a 240-gallon receiver tank is the right answer when both sustained CFM output and low duty cycle operation matter. Three-phase motors at this HP run cooler and start more cleanly than single-phase equivalents. The 240-gallon tank reduces how often either pump needs to cycle, which means the motors spend more time at rest even during a heavy production shift. The result is a compressor system that can run continuously for years with lower maintenance requirements than a smaller or single-phase unit at the same HP.
Key Features
- 15 HP total output: Two 7.5 HP three-phase pump-and-motor assemblies in duplex configuration
- 240-gallon receiver tank: Maximum storage -- lowest duty cycle in the 15 HP duplex class
- Three-phase power (HC2): 208V or 230V/460V -- cleanest starts, best thermal performance, lowest operating amperage
- Alternating lead/lag control: Automatic pump rotation distributes wear and run hours evenly
- Redundant standby operation: One pump continues while the other is serviced -- no full air outage
- Cast Air construction: American-made, commercial-grade components rated for continuous industrial use
