The present invention relates to fire fighting trainers and in particular to the personal breathing apparatus used in such training. More particularly, the present invention relates to the canisters used to supply air to the breathing apparatus during such training. A training canister for use with a personal breathing apparatus supplements filtered air with oxygen supplied by an internal cylinder. The canister has an integral filter providing airflow to the breathing apparatus, and utilizes a miniature high pressure valve to release supplemental oxygen into the system from an oxygen cylinder charged to up to 2000 psi. The training canister simulates operational equipment in size, shape, integration to the personal breathing apparatus, and actuation. Patents. AW
