In an emergency, it can receive air from an air cylinder and be used as a breathing apparatus.
Supply air masks are respiratory protective devices used in workplaces, fire scenes, ships, tunnels, and other locations where there is a risk of inhaling oxygen-deficient air, particulate matter, toxic gases, or vapors. They are typically used as airline masks. In case of an emergency where the supply of air is interrupted or as needed for work, they are designed to receive air from a portable high-pressure air container (air cylinder) and can be used as air respirators.

basic information
◆ Equipped with an automatic switching device for the air supply source Normally used as a pressure demand type airline mask. When the airline supply pressure drops below 0.2 MPa, it automatically switches to air supply from the emergency escape cylinder. ◆ Three alarm functions - When the airline supply pressure decreases (approximately below 0.3 MPa), an alarm is sounded by a whistle. - When the air supply switches to the cylinder, an alarm is sounded by vibrating the medium pressure hose between the facepiece and the waist belt in sync with inhalation. - Additionally, when the remaining pressure in the cylinder drops below approximately 6 MPa, an alarm is sounded by a whistle. ◆ Lightweight and compact emergency escape cylinder: Approximately 1.4 kg Usable time: Approximately 5 minutes (breathing rate of 35 L/min, full charge pressure of 19.6 MPa)
