The ROLAIR® 9-Horsepower Air Compressor delivers powerful performance for industrial applications. The compressor boasts a 9-horsepower Honda engine for fast, efficient pressurization. Its tank holds 20 gallons of air in reserve for your most intense tasks. It delivers more than 20 cubic feet per minute (CFM) at 90 pounds per square inch (PSI) and creates enough pressure for your toughest industrial tasks. When idle, the engine automatically adjusts to accommodate the lower power requirements and saves fuel during stop-and-go jobs. It also protects itself against serious issues by shutting down when oil levels drop too low. The heavy-duty air compressor includes a belt tightener to adjust performance and durable tires to help move it from place to place.
