The C50 First Responder Respirator Mask shares key technologies with the U.S. M50/JSGPM (Joint Services General Purpose Mask) to provide maximum operational flexibility. It is capable of countering multiple threat scenarios, including Chemical, Biological, Nuclear and Radiological (CBRN) agents, Riot Agents, Toxic Industrial Chemicals (TICs), and Toxic Industrial Materials (TIMs).

The C50 offers high protection, outstanding field of vision, and superior comfort. Its innovative design features optimize the user's time in the operational area. The C50 is ideal for battlefield CBRN protection, first responders, correctional officers, specialist law enforcement &amp; counter terrorism operations.

The FM54 Air Purifying Respirator provides Specialist Operators maximum protection and total flexibility in a single mask. The FM54 provides protection to the face, eyes and respiratory tract from Chemical, Biological, Radiological and Nuclear (CBRN) threats, Riot Agents, Toxic Industrial Chemicals (TICs) and Toxic Industrial Materials (TIMs) while maintaining extreme user flexibility as mission profiles change.<br><br>

The FM54 functions in both negative and positive pressure modes (APR, SCBA, CCBA and PAPR). The enhanced, robust lever located on the VREU (Variable Resistance Exhalation Unit) switches mode from positive to negative pressure without removal of the optional VPU (Voice Projection Unit) or loss of protection.

The state-of-the-art ST54 Tactical Operator SCBA is developed specifically for the tactical officer and technician applications where the operator needs to respond to ever changing operational conditions. It is the base to a multi-mission Respiratory Protection System which provides for operational flexibility to the operator and mission commanders in the field to tailor the PPE response based on the available intelligence. Depending on the threat or operational situation at the scene of an incident, the ST54 SCBA can be configured to provide the appropriate protection.<br><br>

The ST54 SCBA combines Avon Protection Systems' M53A1, FM53 and FM54 respirators with new and innovative modular breathing apparatus technology to provide positive pressure SCBA and/or PAPR capability. The ST54 system provides the operator with total flexibility to select the necessary level of protection quickly and efficiently without degradation of operational effectiveness. Designed with the tactical mission in mind, the system incorporates non-reflective black components and warning whistle, which can be silenced.
