6L Air Breathing Apparatus empty cylinder with valve
Cylinder material:carbon steel
cylinder valve size:M18*1.5
Operating temperature:-30C to +60C
Service life:15years2.Breif introduction:(2L, 4.7L,6.8L,9L,12L) It is composed of high-strength aluminum alloy liner and fully wrapped carbon fiber
composite material, which is high strength, light weight. The gas cylinder for 6L is in steel material.
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)
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
= = 68 Min
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 the working time before or in the progress of using the gas cylinder.
