Firefighters must wear respiratory protection in emergency situations during forest fire fighting and rescue operations. This compact oxygen mask provides short-term, comprehensive respiratory protection with isolation, internal circulation, and a self-contained oxygen source. It is unaffected by the external air environment and is suitable for firefighters fighting forest fires and escaping dangers in hazardous environments such as dense smoke, toxic gases, high-temperature airflow, and hypoxia
Firefighters must wear respiratory protection in emergency situations during forest fire fighting and rescue operations.

Innovative features:
The overall design of this self-generating oxygen mask is compact and small, making it easy for firefighters to carry and suitable for head equipment such as helmets and goggles.
The mask and oxygen-generating component are modular and split in design, both of which are quickly donned with Velcro. The oxygen-generating component is a neck-hanging type, which ensures that the shaking of the medicine tank during firefighters' escape operations does not affect the airtightness of the mask, improves safety during use, and facilitates logistical management work such as separation maintenance and replacement of consumable parts.
The oxygen generating component uses chemical oxygenant and is a non-pressure container. It can be stored for a long time under normal conditions and requires little inspection and maintenance.
Model: HFZY15, provides at least 15 minutes of escape protection time, and the protection time when sitting or lying down is greater than 30 minutes.
Intake temperature <50C
Oxygen concentration > 21%
Carbon dioxide concentration <3%
The whole machine weighs about 0.8kg
Storage validity period: 4 years
