CS-PAPR SD
Short Duration Combination System Powered Air Purifying Respirator
Avon Protection's CS-PAPR SD is a CBRN Combination System Powered Air Purifying Respirator (PAPR) designed for short-duration use, integrated with a Combination Respirator Unit (CRU).
CS-PAPR SD provides military special forces and tactical teams with the capability to switch between breathing protection levels dependent on threat for safer operation for the wearer. CS-PAPR SD has been designed as a smaller, compact lower-profile system for greater operational flexibility to enable users to remain uncompromised on target for up to 20 minutes.
Avon Protection’s patented PAPR technology allows users to seamlessly switch between Air Purifying Respirator (APR), PAPR (Powered Air Purifying Respirator), and the option to transition to short-duration SCBA when operating in high-contaminant or oxygen-deficient environments. A single hose connection across all modes keeps one side of the mask clear, maintaining unobstructed weapon sighting and enhanced situational awareness.
Built around a modular methodology, CS-PAPR SD can be easily added to existing fielded systems, including the FM53/4 APR and ST53 SCBA configurations, allowing users to build on existing equipment investment.
Suitable for:
- Military
- Special Forces
- First Responders
- Navy
