3. Different usage times: Fire self rescue respirators are generally shorter; Air respirators can last for more than 1 hour, and can be even longer depending on the model;

4. Structural performance: The fire self rescue breathing apparatus is easy to operate and use. Generally, factories have backup equipment, but there are few backup equipment available. Most of them are used by professional personnel in emergency rescue situations.
