SCBA with Electronic Audible and Visual Alarm
Description:
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.

sealing ring |
1. It has elasticity and resilience. 2. Have appropriate mechanical strength, including tensile strength, elongation and tear strength. 3. Stable chemical properties, not easy to swell in the medium, thermal shrinkage rate is small. It does not decompose and soften at high temperature, and does not harden at low temperature. 4. Good oxygen resistance and aging resistance, durable. 5. Does not corrode the contact surface, does not pollute the medium. |
1. The sealing ring is made of ordinary material, and the phenomenon of white or light transmission occurs when stretching and spring back.. 2. Its elasticity and resilience are poor. 3. Poor tensile strength and tear strength. 4. Its chemical properties are unstable |
Backing plate |
The back frame and strap are flame retardant, waterproof, anti-static function, and resistant to impact, acid corrosion, the use temperature is above -40℃~+140℃. |
The back frame and strap are made of common material, easy to damage and changeable. Narrow temperature range. |
Air supply valve |
The air supply valve can automatically adjust the opening volume of the valve according to the wearer's breathing volume. In addition, the air supply valve is equipped with an automatic positive pressure mechanism, which can ensure that the wearer is in a positive pressure state in the mask no matter inhaling or exhaling during work. |
The imitation air supply valve is easy to malfunction. After the air supply valve is opened, the lever cannot be well positioned under the positive pressure lever assembly, resulting in air leakage after the cylinder is opened. |
