Replacement D-air® Road Shield gas generator for the Smart Air airbag device, Dainese’s innovative airbag system. The strength of the device is precisely the triple-activation airbag that operates through the practical built-in gas generator that can easily be replaced by the end user independently due to the Fast Replacement System (FRS). The airbag must then be replaced by authorized personnel after three uses. The D-air® Road Shield gas generator replacement is useful precisely because the airbag can be reset easily if there’s a fall on the trip, so you can get back on the road without having to go to an authorized dealer for a replacement. D-air® Road Shield generator contains ergon and helium gas and a pyrotechnic charge, and can be transported via airplane after notifying the airline.
