The Rolair 5230K30CS Constant-Run Compressor is a heavy-duty, professional-grade air solution designed for high-demand applications. Powered by a robust 5.0 HP motor running at 1740 RPM, this compressor delivers an impressive 18.8 CFM at 90 PSI, making it ideal for powering multiple pneumatic tools simultaneously on commercial job sites.
This model is designed with a constant-run feature, allowing the motor to run continuously under heavy loads while regulating pressure through a pilot valve. This design protects the motor from damage and extends its service life. It includes a two-stage cast-iron pump, multi-finned intercoolers, and an air-cooled aftercooler for enhanced efficiency and thermal control.
With a 9-gallon twin tank configuration, rugged steel construction, and a wheelbarrow-style design with 3.5-inch wheels, the Rolair 5230K30CS is built for job site durability and ease of mobility.
