Air Spare Cylinder:

Carbon fiber composite cylinder, its liner made of high strength corrosion resistant aluminum alloy, carbon fiber wrapped around the middle, the surface layer of glass fiber package. Bottle thread of M18 × 1.5, cylinder valve outlet thread of G5 / 8.


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= = 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 working time before or in the progress of using the gas cylinder.
