The Chicago Pneumatic RCP-C15123D4 is a 15 HP duplex compressor built with two 7.5 HP cast iron, two-stage pumps sharing a 120-gallon ASME receiver. Instead of putting the entire shop’s air supply on one pump, the duplex design gives you two complete compressor systems that can operate independently, with an included alternator rotating which side starts first. That means one compressor can be isolated for maintenance while the other continues supplying air, helping prevent a routine service job from becoming a full shop shutdown. The system delivers 46 CFM at 100 PSI, reaches 175 PSI maximum pressure, and requires 460V 3-phase power. Note: published horsepower information conflicts in one field, so confirm the nameplate rating if motor sizing is critical to your installation.
The alternator is central to the way this system manages two pumps. It rotates the starting sequence so both compressors share operating hours and starting cycles instead of leaving one unit idle until it is suddenly needed. Under lighter demand, one pump can handle the load; when demand increases, both can contribute. Magnetic starters are included, and each pump uses two-stage compression with cooling between stages to support higher pressure with better temperature control than a comparable single-stage design. The solid cast iron construction also makes the pumps suitable for long-term service, with rebuildable components such as rings, valves, and gaskets rather than treating the pump as disposable equipment.
This configuration is aimed at multi-bay automotive shops, production and fabrication facilities, fleet and municipal maintenance operations, and other workplaces where compressed air is essential to daily operations. The shared 120-gallon receiver provides substantial stored air, while the independent pumps provide an important layer of operational redundancy. At roughly 1,131 lbs, this is substantial stationary equipment that requires a properly planned installation, including appropriate floor support and electrical service. For businesses where compressor downtime directly affects productivity, the duplex architecture provides a practical advantage that a single larger pump cannot: continued air service when one side needs maintenance.

Approvals, stated plainly
The receiver is described as an ASME tank, and that is a real and useful statement about the pressure vessel. Beyond it, this listing makes no third-party approval claim — there is nothing here about the control gear or the assembly as a whole, and we are not going to imply one by leaving the subject vague. If your inspector, insurer or internal safety programme wants approval documentation covering the electrical package as well as the vessel, ask us before you order and we will request it from the manufacturer in writing. That is a much better conversation to have now than at commissioning, when the machine is already bolted down.
Shipping & Delivery
Ships by palletized freight to the lower 48 states, with shipping quoted live at checkout based on your delivery address.
At approximately 1,131 lbs, plan for a properly rated forklift, loading dock or carrier terminal pickup. Residential delivery carries an additional fee and should be discussed with us before ordering.
Inspect before signing. Check the pumps, tank, starter enclosure and pallet with the driver present. Record any damage on the bill of lading and take photographs before accepting the shipment.
Warranty
The listing states a 2-Year Full Warranty covering the complete machine.
If a failure occurs, stop using the compressor and contact us before disassembly. Do not open the pumps, starter or alternator before the claim is initiated. Photograph the condition as found and keep the machine intact for inspection.
