ST53 FM53 Twin Port Self Contained Breathing Apparatus with Specialist Responder Kit

The ST53 combines Avon Protection's FM53 mask technology with an advanced modular breathing apparatus to provide positive pressure SCBA and/or PAPR capability for specialist operations. Developed with the unknown elements of a threat scenario in mind, the ST53™ is the most advanced CBRN respiratory solution on the market. It enables a fast response to changing operational conditions in one complete modular system. A switch between negative (filter) and positive (SCBA) pressure is achieved at the flick of a lever on the front of the mask. And by attaching a short or long duration compressed air cylinder, it is possible to enter a location on filter mode, assess the situation and change to SCBA mode if the need arises.
