The Chicago Pneumatic RCP-C581VS is a 5 HP, two-stage air compressor built around one specification that matters for long-term ownership: its 700 RPM all-cast-iron pump. By turning the pump at a relatively low speed, the compressor reduces the rapid cycling and mechanical wear associated with faster reciprocating pumps. It delivers 18 CFM at 100 PSI, reaches a maximum of 175 PSI, and stores compressed air in an 80-gallon vertical ASME tank. The trade-off is weight—at 580 lbs, this is equipment meant for a permanent installation on a level, solid floor. It requires 208-230V single-phase power, so have an electrician confirm the circuit and disconnect requirements before installation.
The all-cast-iron, two-stage pump is what separates this model from lighter-duty compressors. Air is compressed in two stages to reach higher working pressure, while the heavy cast-iron construction is designed for durability under repeated use. The 700 RPM pump speed also supports quieter operation and reduced wear over time. An 80-gallon receiver provides a substantial reserve of stored air, helping the system handle intermittent demand without forcing the pump to start and stop as frequently. A magnetic starter is included for motor control and thermal overload protection, while the 3/4-inch tank outlet provides the connection point for your shop's air system.
This compressor is a strong fit for one- and two-bay professional shops, serious home garages, and workshops that need more air capacity than a typical single-stage compressor can provide. Its combination of a slow-speed cast-iron pump, two-stage compression, 18 CFM output, and an 80-gallon vertical tank makes it particularly suitable for shops looking for a permanently installed compressor designed for regular, long-term use.

Certification, Stated Honestly
The manufacturer describes the receiver as an ASME tank. That is the pressure-vessel certification relevant to a tank operating at 175 PSI.
Our data records no third-party electrical or complete-machine safety listing for this model, so we will not imply one. If your fleet policy, local inspection requirements or insurer requires a specific listing, tell us before ordering and we will confirm in writing whether this compressor carries it.
Shipping & Delivery
Ships as crated, palletized freight within the lower 48 states. You will need a forklift or loading dock to receive it. If neither is available, terminal pickup with suitable transport is an alternative. Residential delivery carries an additional fee.
Inspect before signing. Check the crate and machine with the driver present. Record any damage on the bill of lading and photograph the pallet before breaking it down.
Warranty
The listing states a 2-Year Full Warranty covering the complete machine, including the valves.
If a failure occurs, stop using the compressor and contact us before disassembly. Keep the pump and other affected components intact for inspection, photograph the condition as found, and follow the manufacturer's warranty process.
