AYO BT Inlet Module – BTi

BTi is the Inlet Module within the AYO Breathing Trainer series. It contains an inlet air adjustment dial, and a patented Push-fit & Twist-release connection to connect with an AYO MA mask assembly.

Although it is named as Inlet Module, which is by default fitted at the left side of the mask as an inhalation resistance adjustment module, it can also be fitted at the right side of the mask for other configurations of AYO BT.
