The Chicago Pneumatic RCP-C581V is a 5 HP two-stage compressor built around a solid cast iron pump and an 80-gallon ASME/CRN vertical receiver. It delivers 18 CFM at 100 PSI, reaches 175 PSI maximum pressure, and operates on 208-230V single-phase power, making it a practical fit for smaller shops that do not have three-phase service. Its clearest differentiator is the 2-year full warranty, which the product listing states includes the valves—an important point because valves are wear components commonly excluded from compressor coverage. The vertical tank also keeps the receiver upright, using less floor area than a comparable horizontal configuration.
The two-stage pump is designed to handle higher pressure more effectively than a single-stage design by compressing the air in two steps with cooling between them. That helps the compressor maintain 175 PSI while managing the heat generated during compression. The solid cast iron construction adds substantial mass to the pump, helping absorb and dissipate heat while providing cylinders that can be serviced rather than simply replaced. The result is a compressor built around long-term mechanical serviceability, while the 80-gallon receiver provides stored air for short periods of higher demand. The vertical layout adds another practical advantage: storage capacity without spreading the tank across valuable floor space.
This RCP-C581V is suited to two- and three-person automotive shops, one-person light body shops, and smaller service operations that need substantial air storage from a single-phase compressor. It makes particular sense where floor space is limited but ceiling height is available, since the vertical receiver concentrates the machine's footprint in a smaller area. With its 5 HP motor, 80-gallon tank, and 175 PSI maximum pressure, it is positioned for shops that need more than an occasional-use compressor without moving into a larger three-phase installation. For buyers comparing compressors on long-term ownership costs, the valve-inclusive 2-year warranty is a concrete advantage worth considering.

With no electronic drain, condensate comes out of the tank by hand. On a vertical receiver that drain is at the bottom of a tall column of water, so it is worth doing weekly and worth fitting an accessible drain line if the tank is tucked into a corner.
Certification, Stated Plainly
The product data identifies an ASME/CRN-certified receiver and safety valves. That certification applies to the pressure vessel, rated here at 175 PSI.
The data does not claim a third-party safety listing for the complete packaged machine, so we will not imply one. Receiver certification does not cover the motor, starter or complete assembly. Electrical installation remains subject to local code and qualified installation. If your insurer or facility requires specific documentation, contact us before ordering and we will confirm what this model can provide in writing.
Shipping & Delivery
Ships by palletized freight to the lower 48 states, with shipping quoted live at checkout based on your delivery address.
At 590 lbs, arrange unloading before delivery. You will need a suitable forklift, loading dock or pallet jack on level ground. Terminal pickup is an alternative if unloading equipment is unavailable. Residential delivery carries an additional fee.
Inspect before signing. Check the tank, pump, gauges and fittings with the driver present. Record any damage or shortages on the bill of lading and photograph the shipment before accepting it.
Warranty
The listing states a 2-Year Full Warranty covering the complete machine, including the valves, with no additional purchase required to activate the stated coverage.
If a fault develops, stop using the compressor and contact us before disassembly. Keep the pump assembled for inspection, photograph the condition as found, and allow the warranty claim to be evaluated before opening or removing components.
