O2 ventilation

  • In cold weather it is often so that with closed air supply the motorcyclist's neck zone becomes sealed off by hoods, scarves or neckerchiefs.
  • The concentration of carbon dioxide inside the helmet is a key safety criterion for preventing symptoms of fatigue and the thinning of breathable air.
  • No negative effects on health need be feared as long as the CO2 concentration remains below 3.5 %.
  • In the interests of ensuring stress-free workplace activity the level of CO2 concentration there should not exceed 0.5 %.
  • Even when the neck zone is sealed off as described above and with closed air supply, the helmet guarantees that the CO2 concentration remains below the 0.5% limit as from a speed of approx. 30 km/h.
  • In cases where the helmet is completely sealed as described above, the visor ought to be opened into what is effectively a city-travel position for safety reasons when idling for example at traffic lights - or when travelling through town at low speeds.
