Pneumatic system
At the heart of the 3M™ Scott™ Sigma 2 set is a simple and reliable two-stage pneumatic system. A first breath activated positive pressure
demand valve provides low breathing resistance and excellent dynamic performance – particularly at high flow rates. A first stage pressure
reducing valve features only two moving parts and accepts cylinder pressures of up to 300 bar without adjustment. A cylinder connector
assembly with standard breathing air thread is fitted, with an easily removed bronze filter to protect the pneumatics. The system includes a
shoulder mounted combined pressure indicator with photo-luminescent face markings for low-light legibility and a robust stainless steel and
polycarbonate case with a protective rubber shroud. A warning whistle has an operating pressure of 55 bar.
The Sigma 2 Type 2 self-contained breathing apparatus combines the highest level of respiratory protection in a simple to operate, cost effective piece of equipment that meets the needs of industrial, marine and firefighting.
