Oxygen Breathing Apparatus

  • Spherical larger vision mask, have permanent anti-fog, and anti-scrape wear resisting ability, can keep the mask visual effect for a long time.
    Advanced exhaust structure design to save gas source, which can guarantee the use time is better than the rating.
    Gasbag with high quality material, reduce the air resistance to deformation, make breathing easier.
    Large cross-section hose breathing, breathing more comfortable.
    Special structure proportional valve, make the oxygen supply more stable.
    Unique cooler lid design improvements, do not need to uncover respirator shell, ice can be easily replaced.
    Harness can be easily adjusted to fit any size user.
