The ROLAIR 9-Horsepower Two-Stage Two-Cylinder Portable Gas Compressor delivers enough pneumatic pressure for all your industrial power tools. This device expels air at 20.1 cubic feet per minute (CFM) at 90 pounds per square inch (PSI). It uses gasoline for power so it can pressurize air without any significant delay before you get started on the job. This Rolair air compressor comes with two cast-iron cylinders that withstand high pressure levels and wheels to support the unit's 286-pound weight. It shuts off automatically when oil levels fall too low and protects itself from extensive fuel usage with a built-in idle system. The 9-horsepower air compressor relies on a Honda engine for its speed and efficiency, and it has a retractable starter that protects against accidental engagement.
