Completely in accordance with human body engineering design,shape the back curve of joint human body completely,contact area bigger,wear comfortable.By straps can easily adjust the back contact height and position of joint human body back.Back frame made of lightweight polypropylene materials,impact resistance and corrosion.Overall injection,disinfection, convenient cleaning.The lateral parts without actuate angle,will not cause harm to human anti-slip fabrics and woven belt,wearing more comfortable.Belts buckles made of durable nylon materials, convenient adjustment.Braces fabric for flame retardant material.
 

1. Pressure gauge with alarming whistle 

Main performance

Pressure gauge reading: 0-40MPa, with safety opening.
With fluorescence function, the area of 0-5MPa marked in red. Working pressure: 30MPa

The thimble in the alarm whistle is fixed in the spring by the high pressure air, which is transported by pressure regulator and high-pressure pipelines, when opening the valve of gas cylinder. The thimble is for sealing, it can prevent the medium-pressure air into the alarm whistle and hence, the whistle won't alarm.
When the pressure in the gas cylinder is below 5.5±0.5MPa,the thimble detach the sealing position under the action of the string, the medium-pressure air enter into the alarm whistle at the speed of 5 L per minute. And then, the whistle alarms.
 

Work function

Work pressure of the alarm whistle: 5.5±0.5MPa The whistle will alarm until the air exhaust.
Air consumption: 5 L/ minute Sound level: 90db
Frequency: 3800HZ

 

1. Air supply valve

The air supply valve weights light, has compact structure and is made of the fire impact-resistant material. It can fast connect with the face mask through the string button and fast interface. The air supply valve connects with the pressure gauge through the medium-pressure pipeline. When it occurs the disordered breathing on the user, press the red "ON" button and the air supply valve will increase the amount of gas automatically to 450L per minute (the air supply valve will reach this gas amount within tenths of a second)
The maximum amount of gas : 450L/minute
 

1. Pressure regulator 

Whatever the change of air pressure in the gas cylinder and the user's breathing frequency, the pressure regulator can provide a stable output pressure. The black sealed cap guarantees the authorized maintenance of pressure regulator, it can't be removed privately, otherwise, the person who removes the cap should suffer the consequence.

Mainly parts connected with the pressure regulator:

1. One or two gas cylinder
2. Medium-pressure pipeline, transporting the air to the air supply valve
3. High-pressure pipeline, connecting with the pressure gauge
4. Technical specification

The maximum input pressure: 30MPa Output pressure: 0.7±0.05MPa
Opening pressure of the safety valve: 1.1±0.2MPa
Working temperature: -30ºC-+60ºC (According to the standard of EN137) Type: Dynamic balance

Warning: The pressure regulator only can be maintained by designated person, they are our company's specialist and the maintenance personnel, or the person who has the professional training and get the authorized by our company.

l The mask is anti-fog


7. Gas cylinder

It is composed of high-strength aluminum alloy liner and fully wrapped carbon fiber composite material, which is high strength, light weight.
Service time: It depends on the amount of compressed air and the air consumption of the user and the air consumption depends on the user's work nature.
Work nature Air consumption (L/Min)
Rest 10-15
Mild activity 15-20
Light work 20-30
Intensity work 30-40
High-intensity work 45-55
Work for a long time 50-80
Vigorous activity (few minutes) 100

The amount of breathable air in the gas cylinder
The user can get the value by calculating the product of the volume of gas cylinder and working pressure.
For example: the working pressure of a 6.8L gas cylinder at 30MPa, the air volume is 6.8*30*10=2040L
When the user is in intensity work, the theory time of this gas cylinder is:
The volume of breathable air (L) 2040 (=68mins)
The volume of air consumption (L/Min) 30
This calculation method doesn't consider the purity of air, so it needs add a 0.9 coefficient to correct. The actual air volume in the gas cylinder is: 2040*0.9=1836L. According to this calculation method, the actual use of time is 61.2 minutes. The user can roughly calculate the working time before or in the progress of using the gas cylinder.
