⭐Product Parameter:
⭐Production Process
⭐Superior Material & Construction
Acecare Tech specializes in the production of portable gas cylinders using advanced technology. Unlike traditional steel respirators, our cylinders are made from lightweight aluminum or aluminum composite materials. This results in a 40%–70% reduction in weight, making them ideal for people with respiratory conditions.
Thanks to their lightweight and durable design, our cylinders serve a wide range of uses. They are widely adopted in scuba diving and other recreational fields. These cylinders are used to fill smaller tanks with compressed air for storage, which is far more convenient and efficient than relying on an on-site compressor.
We craft every gas cylinder liner from high-quality 6061 aluminum alloy. The production process includes punching, drawing, heat treatment, CNC flow forming spinning, and specialized inner surface treatment. This guarantees consistent wall thickness and minimal variance across all units.
Each cylinder is built from composite materials for maximum strength and storage capacity. The structure consists of four protective layers:
Aluminum liner
Carbon fiber wrap
Glass fiber wrap
Outer gel protection
This multi-layer design offers outstanding pressure resistance and long-term durability.
- 15-year lifetime warranty;
- 5-year requalification period; 15-year life;
- High Quality, Light-weight, Smooth, easy-care exterior finish.
⭐Real-World Applications
Scuba Diving (Scene 1):
Respiratory Use (Scene 2):
Our cylinders are used in firefighting, technical diving, and emergency air supply. They support mixed gases like He2 + N2 + O2, making them suitable for land and marine applications.

How Many Fills Will I Get?
Estimates below assume: tank filled to 4500 PSI; refills counted until tank pressure drops to 3100 PSI (below that, full-pressure fills aren’t possible); 70°F; ideal-gas math — real-world fills vary with temperature and fill speed.
| Your gun’s air reservoir | Fill type | 6.8L tank | 9L tank |
|---|---|---|---|
| 500cc, filled to 3000 PSI | Full fill (empty → 3000 PSI) | ~6 fills | ~8 fills |
| 500cc, filled to 3000 PSI | Top-up (2000 → 3000 PSI) | ~19 top-ups | ~25 top-ups |
Smaller reservoirs or lower fill pressures = more fills. As tank pressure drops toward your gun’s fill pressure, fills get slower — plan a refill of the tank itself in time.
