Avon Protection System's ST50 SCBA (self-contained breathing apparatus) was developed as a result of extensive field research, evaluation, and customer voices. The lightweight ST50 is NIOSH approved, positive pressure, easy to operate, affordable self-contained breathing apparatus, designed to meet the unique and demanding requirements of Correctional facilities and Plant security. The ST50 deploys a modified, field-proven PC50 + mask that provides high performance, extremely high wearer comfort, unobstructed vision and excellent communication. The small footprint and the durable compact demand valve (CDV) provide high flow to the mask, while the ergonomic back frame and harness assembly provides a comfortable and secure fit for the operator. The ST50 can hold 2216 psi or 4500 psi 30, 45 or 60 minutes carbon fiber cylinders, and comes with a quick-release cylinder belt for easy replacement.
