SCBA with Electronic Audible and Visual Alarm

This air breathing apparatus combines a pointer-type pressure gauge with an electronic audible and visual alarm into one unit. When the cylinder pressure drops to 5.5±0.5MPa, the electronic audible and visual alarm sends out alarming buzzes greater than 90dB, and also emits a white flashing light and red flashing light signal. Compared with traditional pneumatic whistle alarm, the electronic audible and visual alarm has two features: sound and flicker alarm as well as light warning for different pressure stages. This can ensure the respirator users and the supervisors to obtain the air residual pressure information and alarming signal through various ways, so that the users can breathe and evacuate safely.
