Avon’s state-of-the-art ST54 Tactical Operator SCBA has been developed specifically for the tactical officer and technician applications where the operator needs to respond to ever changing operational conditions. 

The ST54 SCBA 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.

The ST54 SCBA combines Avon Protection Systems’ M53A1, FM53 and FM54 respirators (see respirator datasheets for further details) 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. 

The standard ST54 backframe two piece composite assembly with universal cylinder band to accommodate a variety of DOT approved stealth black cylinders from 4500- 5500 psi; 30, 45, 60, and 70 minute duration (70 minute only available with 5500 psi system).

Cylinders
The ST54 two-piece clamshell composite backframe accommodates a variety
of 4500 psi carbon cylinders in durations of 30, 45 or 60 minutes, as well as a
5500 psi carbon cylinder in a 70-minute duration. Both natural and stealth black
cylinder finishes are available along with optional stealth cylinder bag covers. A
quick release universal cylinder band allows for fast and easy cylinder exchange.

End-of-Service-Time Indicators (EOSTI)
The ST54 backframe includes a remotely accessible, chest mounted pressure
gauge (available with stealth black and luminescent face options) for monitoring
of cylinder pressure and an end-of-service whistle alarm that can be disabled
(voids NIOSH approval) if required.

Compact Demand Valve (CDV)
The world’s smallest, most compact chemically hardened demand valve provides
constant positive pressure. With the option to mount on either side of the
respirator, the CDV is unobtrusive and allows excellent integration with weapons
and other tactical gear. The CDV is attached to the respirator via a standard 40mm
thread connection.
