Air Cascade Systems for SCBA and Breathing Air

Max-Air designs and supplies high-pressure air cascade systems for fire departments, dive operations, industrial facilities, military users, and other organizations that need dependable stored breathing air. Systems can be configured for SCBA, SCUBA, and industrial cylinder filling, with storage pressures available up to 6,000 psi.

The right breathing air cascade system depends on your cylinder working pressure, the number of cylinders you need to fill, your desired fill speed, available space, and whether the system will operate with a compressor, fill station, or standalone storage bank.

Max-Air can help configure the storage cylinders, rack, controls, hoses, and filling equipment required for a complete system. Call 830-257-5006 to confirm the correct air storage and filling setup for your application.

How to Choose the Right Air Cascade System

Before selecting an air cascade system, consider these four factors:

  • Cylinder working pressure — Confirm the pressure and size of the SCBA, SCUBA, or breathing-air cylinders you need to fill.
  • Filling demand — Estimate how many cylinders you fill per hour and per day, including periods of heavy use.
  • Storage pressure and capacity — Determine the required storage pressure and the number of high-pressure storage cylinders needed to support your operation.
  • Complete system requirements — Decide whether you need a vertical or horizontal rack, cascade controls, fill hoses, a containment fill station, or connection to an existing compressor.

Frequently Asked Questions About Air Cascade Systems

An air cascade system is a bank of high-pressure storage cylinders connected together to store and deliver compressed breathing air. The stored air can be used to fill SCBA, SCUBA, and industrial breathing-air cylinders without requiring the compressor to run during every fill.

The correct storage pressure depends on the working pressure of the cylinders being filled and the number of fills required. A 4,500 psi cascade system is generally better suited to lower-pressure cylinders, while 5,000 or 6,000 psi storage provides more usable air and better supports filling 4,500 psi SCBA cylinders. Every cylinder, valve, hose, control panel, and regulator must be rated for the system’s maximum operating pressure.

The number of storage cylinders depends on the cascade pressure, storage-cylinder capacity, the size and working pressure of the cylinders being filled, and how many fills are needed between compressor cycles. Many systems use three, four, or more storage cylinders. Max-Air can calculate the required storage capacity based on your actual filling demand.

A manual cascade system requires the operator to open and close each storage-bank valve in sequence while filling a cylinder. An automatic cascade system controls the storage banks and switches between them automatically. Manual systems are simpler and usually cost less, while automatic systems can provide faster, more consistent operation for facilities with frequent filling demand.

Yes. Max-Air can help configure a complete air cascade system based on your cylinder pressure, filling volume, available space, and existing equipment. A system may include high-pressure storage cylinders, a vertical or horizontal rack, cascade controls, pressure gauges, valves, regulators, hoses, and connections to a breathing-air compressor or containment fill station.
