High-reliability oxygen supply: Uses high-pressure compressed oxygen cylinders, with high oxygen purity and no risk of chemical reagent residue (compared to chemical oxygen self-rescuers). Dual-mode oxygen supply (fixed rate + manual supplementation), adapts to different breathing needs.
Long-lasting protection: Can provide oxygen continuously for over 30 minutes, meeting the escape time needs of most scenarios.
Intelligent safety design: Low-pressure audible and visual alarm function, promptly reminds to replace the oxygen cylinder, avoiding the risk of sudden oxygen supply interruption.
The pressure reducing valve has an explosion-proof design and has passed rigorous pressure testing to ensure safety under high temperature/impact conditions.
Humanized experience: Lightweight materials (such as aluminum alloy cylinders), comfortable to wear, do not affect rapid movement.
Quick-open design (pull and use), avoiding complex operations that delay escape time.
