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.
