  • Page 8: Description

    Description Description The G1 SCBA is a pressure-demand self-contained open circuit breathing apparatus (SCBA) operating independent of the ambient air for use in atmospheres immediately dangerous to life or health. Breathable air is supplied to the user from a compressed air cylinder via a pressure reducer, a lung governed demand valve (LGDV) according to EN 137:2006 and a full face mask according to EN 136:1998 (see Operating Manual of full face mask).

  • Page 10: G1 Facepiece (Full Face Mask)

    Description G1 Facepiece (Full Face Mask) The full face mask provides breathable air from the LGDV. The inhalation air flows from the component housing of the mask past the inhalation valve to the inside of the lens (thus keeping the lens fog-free) and then through the inlet valves into the nosecup.

  • Page 11: Mask Versions

    Harness Versions The mask is available with different head harnesses; Kevlar (textile) 4-point or rubber (5-point). The rubber head straps are numbered to indicate the correct tightening sequence. Fig. 2 Kevlar (textile) harness Fig. 3 Rubber harness G1 Integrated SCBA System...

  • Page 12: G1 Demand Valve

    Fixed Push-To-Connect G1 Demand Valve (LGDV) The mask mounted G1 Demand Valve is a pressure-demand LGDV, which maintains a positive pressure in the full face mask while the SCBA is in use. The positive pressure LGDV reduces the pressure coming from the pressure reducer further to provide breathable air to the user.

  • Page 13: Only)

    Description G1 Heads-Up Display (HUD) (Electric Version Only) The HUD is integrated into the LGDV and projects different colored light into the full face mask to indicate current cylinder pressure and alarm status of the device. The HUD allows users to make conclusions about cylinder pressure and alarm status while wearing the SCBA.
