AYO BT Outlet Module – BTo

BTo is the Outlet Module within the AYO Breathing Trainer series. It contains an exhalation valve, and a patented Push-fit & Twist-release connection to connect with an AYO MA mask assembly.

Although it is named as Outlet Module, which is by default fitted at the right side of the mask as an exhalation module, it can also be fitted at the left side of the mask for other configurations of AYO BT when the BTi module is used at the right side of the mask.
