SIGMA 2 TYPE 2

SELF CONTAINED BREATHING APPARATUS

PNEUMATIC SYSTEM
At the heart of the 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 cylinders pressures of up to 300 bar without adjustment. A cylinder connector assembly with standard breathing air thread is fitted, with an easily removed bronzed filter to protect the pneumatics. The system includes a shoulder mounted combined pressure indicator with photoluminescent 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.
