HFZY30 Chemical Oxygen Respirator for Fire Self-rescue

Classification：

Fire fighting equipment

HFZY30 chemical oxygen respirator for fire self-rescue adopts aerospace breathing exhaust gas regeneration technology, directly converting the carbon dioxide exhaled by the human body into oxygen for recycling, achieving miniaturization, portability, and internal circulation air regeneration, providing comfortable and safe respiratory protection for on-site personnel for a long time. The product innovatively adopts a structural design of a full face hood and three-gas paths, effectively solving the problems of poor safety performance, limited use, and low cost-effectiveness ofexisting filter type escape masks. The suction temperature is below 35 ℃, and the core indicators are about 50% better than national standards and other types ofproducts. The product has obtained the 3C certification for fire protection and can be widely used in emergency evacuation of oxygen deficient environ- ments in disaster sites such as fires, explosions, industrial accidents, and underground enclosed spaces.
