The ST53 combines Avon Protection Systems’ FM53 mask with new and innovative modular breathing apparatus technology to provide positive pressure SCBA and PAPR capability.
The ST53 is a Multi-Role Respiratory Protective Equipment (RPE) system that provides the operator with total flexibility to quickly select their protection levels on site where the user needs to respond to changing operational conditions.
The seamless transition between APR protection (negative pressure) and SCBA protection (positive pressure) lets users maximize their time on scene, maintaining the highest levels of protection.
-Includes a unique close fitting filter design, giving the user greater visibility, improved weapon sighting and manoeuvrability
-Includes a remote accessible, chest mounted pressure gauge for monitoring of pressure, as well as whistle for end of service alarm which has the option to be disabled if required
-The ST53SD provides the option of either a remote whistle and pressure gauge or a single pressure gauge attached directly to the regulator body
-The world’s smallest, most compact chemically hardened demand valve provides constant positive pressure
-For enhanced voice amplification, an optional Voice Projection Unit (VPU) with internal microphone can be connected via the Electronic Communication Port (ECP). The internal microphone may also be used for radio communications
