Max-Air provides high-pressure SCBA air compressors for fire departments, fire brigades, and public-safety organizations that need dependable cylinder filling. Systems are available for direct cylinder filling or use with cascade storage, with configurations available up to 6,000 psi.
For departments that prefer a vertical configuration, the MA90 VRT 6K fire department SCBA compressor provides 6000 PSI capability for SCBA cylinder filling and cascade system replenishment.
Choosing the right breathing air compressor depends on your cylinder pressure, the number of cylinders you fill, your available electrical service, and whether you use a containment fill station or cascade system.
Departments that need faster back-to-back SCBA filling can review our fire department cascade system guide to compare storage pressure, compressor sizing, and fill-station requirements.

Before selecting a breathing air compressor, consider these four factors:
| Feature | MA90 SFD 6K | MA90 VRT 6K | MegaMax 6K |
|---|---|---|---|
| Maximum Pressure | 6000 PSI | 6000 PSI | 6000 PSI |
| Charging Rate | 10.8 SCFM | 10.8 SCFM | 20–27 SCFM, depending on configuration |
| Configuration | Stationary, continuous-duty | Vertical cabinet | Vertical enclosed cabinet |
| Electrical |
Single-phase: 208, 220 or 230 V Three-phase: 208, 230 or 460 V |
Single-phase: 208, 220 or 230 V Three-phase: 208, 230 or 460 V |
Single-phase: 208, 220 or 230 V Three-phase: 208, 230 or 460 V |
| Breathing Air / Purification |
39K CFT or higher, depending on configuration CGA Grade E breathing air |
70K CFT CGA Grade E breathing air |
70K CFT or higher, depending on configuration CGA Grade E breathing air |
| Best Fit | Small-to-medium fire departments needing dependable SCBA cylinder filling and cascade-system replenishment | Fire departments wanting a vertical 10.8 SCFM system for SCBA cylinder filling and 6000 PSI cascade replenishment | Higher-volume filling operations requiring 20–27 SCFM and repeated SCBA or cascade-system filling |
Compressor selection depends on cylinder pressure, peak filling demand, available electrical service, cascade-storage requirements, and installation space. Contact Max-Air at 830-257-5006 for help selecting the correct configuration.
The correct compressor depends on your SCBA cylinder pressure, how many cylinders you fill per hour and per day, your available electrical service, and whether you use direct filling or cascade storage. Use the Find the Right Compressor tool or call Max-Air at 830-257-5006 to confirm the proper configuration.
A 5,000 psi system is suitable for many standard SCBA cylinder-filling applications, while a 6,000 psi system provides additional pressure capacity for certain storage and filling configurations. The correct choice depends on your cylinders, cascade-storage pressure, fill station, and department requirements. Max-Air can confirm the appropriate pressure before ordering.
Not every department needs cascade storage. A compressor can fill SCBA cylinders directly, but cascade storage can improve filling speed and provide stored breathing air during periods of heavy demand. The best setup depends on your daily cylinder usage, desired fill time, available space, and budget.
Fill time depends on the compressor’s airflow, the cylinder’s size and starting pressure, the final fill pressure, and whether the cylinder is filled directly or from cascade storage. Higher-output compressors and properly sized storage systems can reduce turnaround time. Max-Air can calculate expected fill times for your department’s cylinders and filling demand.
Maintenance varies by compressor model and operating hours but generally includes checking oil levels, draining condensate, inspecting belts and hoses, replacing purification cartridges, and following the manufacturer’s service schedule. Fire departments should also perform required breathing-air quality testing and keep maintenance records for the complete filling system.
