    What to do if my Dräger PSS 3000 Diving Instrument face mask is leaking air?
    • R
      Robert GreeneAug 13, 2025
      If your Dräger Diving Instrument's face mask is leaking air, it might be due to a leaking O-ring in the lung demand regulator. Try renewing or lubricating the O-ring. Also, ensure the head straps are tight. If the exhalation valve or speech diaphragm is defective, a service task is required.
