Controled by breath, fully automatic All details here : https://www.b4x.com/android/forum/threads/experimental-powered-air-purifying-respirator.116659/ You will need this to adapt the mask to the turbine : https://www.thingiverse.com/thing:4295491 Put the sound on, imagine you have a dust mask on your head and you breathe normally into the mask equiped with a powerful FFP3 cartridge... https://www.youtube.com/watch?v=nY4yTEhh4uY Finally I must say that this system provides a really effortless way to wear a mask. There is no effort to breathe, no moisture accumulated into te mask. And the positive pressure applied into the mask gives to the user a perfect clean fresh and filtered tidal volume of air ! You can also use it as a spirometer. Unplug the venturi from the turbine then connect the adapter and blow !
