The Chicago Pneumatic RCP-7581VS is a 7.5 HP two-stage compressor with an 80-gallon vertical receiver, designed around heat management and automatic protection. Its pump combines solid cast iron cylinders with aluminum heads, intercooler, and crankcase, plus an integrated aftercooler to help control temperatures between compression stages and before air enters the tank. The machine operates on 208-230V single-phase power, reaches up to 175 PSI, and includes a factory-installed magnetic starter. Note: published information lists the motor as both 7.5 HP and 8 HP and gives different air-delivery figures, so confirm the exact motor and CFM rating before ordering.
The mixed-metal pump is the main feature to understand. The cast iron cylinders provide the wear resistance needed where the rings operate, while the aluminum components help move heat away from the pump. Because the second compression stage generates significant heat, controlling that temperature can reduce thermal stress and limit the amount of moisture carried into the receiver. The integrated aftercooler continues that process by cooling compressed air before it reaches the tank. Automatic protection adds another layer of convenience: a low-oil level switch shuts the compressor down if oil drops too far, an automatic tank drain removes accumulated condensate, and the magnetic starter provides motor thermal protection. A fully enclosed high-flow belt guard protects the drive while allowing the airflow needed for cooling.
This RCP-7581VS is suited to busy independent automotive shops, light industrial and fabrication operations, and workshops with available vertical space but limited floor area. The 80-gallon vertical receiver provides substantial stored air without requiring the footprint of a comparable horizontal tank. It is also a practical choice for shops that want key protection and maintenance features built into the compressor rather than added later. For applications where air delivery or motor sizing is critical, verify the conflicting published specifications with Chicago Pneumatic before making the purchase.

Overall width and height appear in our data as bare numbers with no unit recorded against them, so we have left them out rather than guess. Ask us and we will confirm the full envelope before you plan the space.
Certification, Stated Honestly
The manufacturer's description states that this machine has an ASME/CRN-certified tank and safety valves. This is pressure-vessel certification.
Our data does not record a third-party electrical or complete-machine safety listing for this compressor, so we will not imply one. If your insurer, local inspector or company policy requires a specific listing, tell us before ordering and we will confirm in writing whether this unit carries it.
Shipping & Delivery
Ships by freight to the lower 48 states on a pallet. You will need a forklift, loading dock or suitable equipment to unload several hundred pounds safely. Terminal pickup is an alternative if you do not have unloading equipment. Residential delivery carries an additional fee.
Inspect the crate before signing. Record any damage on the bill of lading with the driver present and photograph the pallet before moving or opening the shipment.
Warranty
Chicago Pneumatic publishes warranty terms for its compressor range, and this listing links to that policy rather than restating it. Because our model-specific record does not provide a warranty duration, we have not published one here. Ask us for the current terms in writing before ordering.
If a failure occurs, stop using the compressor and contact us before disassembly. Keep the pump, motor and pressure switch intact for inspection, photograph the condition as found, and follow the manufacturer's claim instructions.
