1L Portable Refillable Scuba Diving Cylinder

Compact 1L Refillable Cylinder for Short Underwater Dives

This 1L portable scuba cylinder is designed as a compact air supply for short, shallow underwater activities. Constructed from robust, high-strength materials, it is engineered to withstand pressures up to 20 MPa (200 BAR / 3000 PSI) while maintaining stable performance. At just 35 x 9 cm and approximately 2.14 kg, it fits easily into most dive bags and integrates well with existing gear as a backup or auxiliary air source.

With a gas capacity of approximately 200L (compressed air), this mini cylinder supports about 15-20 minutes of underwater breathing time under typical shallow-use conditions, or around 130+ surface breaths. It is suitable for use as an emergency backup, for short recreational dives, equipment checks, boat work, or pool training. The refillable design allows you to recharge the cylinder with compatible filling equipment, helping reduce ongoing rental and refill costs when used correctly within local regulations and standards.

Why It's a Smart Choice

• Compact and travel-friendly - Small 35 x 9 cm profile and manageable weight make it easy to transport and stow with your main dive setup.
• Refillable design - Can be recharged with compressed air (up to 20 MPa) using appropriate filling equipment, offering ongoing use without frequent cylinder replacement.
• Reliable short-duration air supply - Approx. 200L gas capacity provides 15-20 minutes of breathing in shallow water, ideal as a backup or for brief underwater tasks.
