The M50 Joint Services General Purpose Mask (JSGPM). Protecting today’s warfighter with tomorrow’s technology.

 

The design and development by Avon Protection of the M50 mask has resulted in the most advanced general service respiratory protection mask to date, offering significant improvement in comfort, usability, operational effectiveness and protection.

 

A revolutionary cast flexible visor offers wide, optically correct vision together with being impact and scratch resistant.

 

Close fitting, curved conformal filters offer improved weight distribution and reduced breathing resistance, as well as enhanced protection against toxic industrial agents. An integrated Electronic Communication Port allows for an internal microphone for communication systems. In addition, a high flow hydration connection enables quick and easy fluid intake.

 

The M50/JSGPM (Joint Services General Purpose Mask) has been selected by the U.S. Department of Defense to replace existing respiratory protective masks used by several branches of the military.

 

The M50 provides outstanding protection from battlefield concentrations of CB agents, toxic industrial materials, toxic chemicals and particulate matter. The streamlined design offers unique twin conformal filters for low breathing resistance and reduced burden, excellent weapons integration and balanced weight distribution.

 

The M51 variant has been specifically designed for combat vehicle operators. Consisting of the M50 mask in conjunction with a CVC hood for head and neck protection (constructed from Gore Chempak™ barrier technology), a communication lead and hose to integrate with vehicle blowers and COLPRO systems.
