DOT Cascade Storage Systems

DOT cylinders, DOT bottles

HC-Series Cylinders are advanced, computer-designed steel cylinders that lead the global gas industry in capacity-to-weight ratios. These high strength, light weight alloy cylinders feature higher gas capacities that allow for longer service between filling cycles- delivering reduced costs for handling and maintenance. Built to exacting standards for years of durable service, HC-Series cylinders are 100% ultrasonically tested and feature leak-before-break pressure vessel technology.

DOT (Department of Transportation) bottles used in a high pressure cascade system greatly increase overall efficiency. A properly sized high pressure cascade system allows peak demands to be met with a smaller compressor than would otherwise be required. Stored air in DOT bottles can also be utilized to carry on operations in the event of compressor failure, loss of power to run a compressor, or in areas where compressors are not available.

5000 psi and 6000 psi DOT bottles are available for fixed and transportable applications and are complete with all necessary mounting racks and hardware.

Star Air Systems provides you with complete control over your air cylinders, check out our fill stations for filling options.
