Air Cylinders - Carbon-fiberglass Composite Material, 4500 Psig High Pressure Models | Extended Duration Air Supply Options, Lightweight Design

In 1976, MSA introduced the Composite I Cylinder -- the first fully-wound composite cylinder. A combination of aluminum and fiberglass, the Comp I cut cylinder weight virtually in half at that time. Since then, more than 300,000 MSA fully-wound composite cylinders have been placed into service with an untarnished record of performance.

Designed exclusively for MSA Air Masks, Carbon-Wrapped Cylinders incorporate the same proven technology found in earlier MSA fully-wound composites. And theya re available in both high-and low-pressure models.

With the high-pressure Air Masks, you can choose from three 4500 psig Carbon-Wrapped Cylinders. The H- 30 Cylinder provides a 30-minute rated air supply and maximum maneuverability, which may be required for confined space rescues. For longer duration air supplies, you can choose either H-45, H-45LP (Low-Profile) or H-60 Cylinder, which provide a 45- or 60- minute air supply, respectively. Lowpressure Air Masks are suitable for use with the L-30 Cylinder, a 2216 psig cylinder rated for 30 minutes. Or, use the L-30 +, a 30-minute-rated cylinder pressurized to 3000 psig.
