One relies on a chemical reaction to "generate oxygen out of nothing," requiring a waiting period for the reaction to initiate during critical moments; the other is filled with high-pressure oxygen, allowing immediate "oxygen release" with a simple turn of the valve. Chemical oxygen and compressed oxygen self-rescuers operate on vastly different principles but serve the same purpose!

The primary use of chemical oxygen compressed self-rescuers is to provide emergency oxygen supply in high-risk work environments. Don't dismiss it as "disposable" and short-lived—it expends all its chemical reactions in exchange for your hope.

Product Features

1. Long usage time, compact size, lightweight, and easy to carry.

2. Features three oxygen supply modes:定量供氧 (quantitative oxygen supply), automatic oxygen replenishment, and manual oxygen replenishment. Ensures safer and more reliable use.

3. Utilizes a dual-circuit breathing system, eliminating inhalation of calcium hydroxide dust, non-irritating, low breathing resistance, low inhalation temperature, comfortable breathing, and high safety and reliability.

4. Reusable after oxygen refilling and chemical replacement, with low usage costs.

5. Oxygen pressure gauge allows intuitive observation, making it easy to determine available escape time.

6. Easy to assemble, simple structure, few vulnerable parts, and convenient maintenance and repair.

The chemical oxygen self-rescuer may be used only once, "yet its significance weighs a thousand pounds"! It "silently stands by" until a life-or-death moment, unleashing its full "vitality," burning itself to become the light that illuminates the path to survival.
