Air Systems International Twin Air Series compressors are employed for supplying breathing air to workers in confined spaces providing air for pneumatic tools and equipment. These compressors support air-operated systems in remote areas without access to a fixed air supply. They feature 10-inch pneumatic tires that enable easy portability and a built-in skid plate to facilitate stair climbing, making them suitable for use in various work environments. These Twin Air Series compressors have an 8-gallon Twin-Air tank assembly that provides 8.5 cubic feet of air storage at 110 psi, allowing stable air supply even during peak demand periods. They are equipped with 1/2 inch 5000 Series Hansen-style coupling outlets for easy connection to air hoses.
