The Avon CS-PAPR™ is the newest generation of CBRN Powered Air Purifying Respirator (PAPR) designed for use in Combination Unit Respirators.

The capability to change levels of protection dependent on the threat, now provides the wearer with increased duration on target and safer operation.

Utilizing the Avon MP-PAPR module along with the patented combination hose module, the wearer can seamlessly switch between APR, PAPR and SCBA modes of protection. The single air hose connection for all modes allows the wearer to retain a clear mask cheeks for optimum weapon sighting.

The low profile shape of the Avon CS-PAPR delivers best in class integration with SCBA systems, benefiting the wearer with reduced weight and size compared to traditional systems.

Modular Methodology allows the user to either add the Avon CS-PAPR to existing fielded systems such as the FM53/4 APR and ST53 SCBA, use as a regular PAPR (Avon MP-PAPR) or revert back to the Avon EZAir configuration.
