- DESCRIPTION OF THE T8000 (Figure 1)
The T8000 is a breathing apparatus able to meet a wide variety of needs for respiratory protection. The T8000 is composed of:
- The carbon compressed air cylinder
- The backplate with it’s harness, two pressure regulators (high pressure reducer and lung demand valve) and pressure gauge with
warning device
- The fullface piece
The T8000 is shipped with its storage and carrying box.
Operating principle
Open-circuit self-contained respiratory protection apparatuses work with a compressed-air reserve under high pressure. This apparatus allows users to be supplied with breathing air on demand from the cylinder(s) carried on the back.
The pressure of the compressed air in the cylinder(s) is first reduced to medium pressure by the first stage (high pressure reducer). It then enters the second stage, the demand valve, to arrive in the respiratory mask after pressure has been reduced to a breathable pressure. The demand valve maintains a slight overpressure in the mask, whatever the breathing rate, avoiding any ingress of outside air.Backplate and straps
The backplate ensures comfort and stability when carrying the cylinder. Its anatomical shape is open in the centre to reduce perspiration. It has three carrying handles.
Its variable-length locking collar allows it to be used with all cylinder types.
Quick-tightening straps support the pressure gauge.The backplate and its straps are rot-resistant and self-extinguishing.
