Airtec tube - Compressed breathing air detector tubes
Airtec Tube for Cylinder / Compressed Breathing Air / Air Line Test.
Airtec tubes are a convenient and simple system for testing of a gas cylinder, compressed breathing air and air line. Industrial operations often produce, or are performed in the presence of harmful airborne contaminants. When self contained breathing apparatus or other devices are used for respiratory protection, the quality of the breathing air requires special attention. Contaminants entering the compressor or contaminants generated by the compressor or cylinder can be harmful to the worker and the respiratory equipment.
Measurement procedure:
 |
1.Install a reducer pressure with gauge and flow metre to a cylinder, compressor or air line and adjust the flow metre the required setting. | |
| 2.Break tips off a fresh detector tube in the tube tip breaker and insert a tube into a tube holder. |
 |
|
 |
3.Attach the rubber tube holder to the flow metre outlet. Make certain the tube arrow on the tube pointing in a down direction. |
|
| 4.Turn on the cylinder or compressor and confirm the flow metre according to each Airtec tube specifications. |
 |
|
 |
5.Time the flow rate with a stopwatch. | |
| 6.As soon as sampling time has elapsed turn off the cylinder or compressor, and remove the tube from the tube holder and then read the colour change layer immediately. |
