ARM Respirator

The Advanced Respiratory Module (also known as ARM Respirator, or simply ARM for short) was a respirator that saw widespread use in a lot of facilities and factories, by both factory workers and researchers during certain scenarios. Its filter cartridge was rather heavy, compared to those used by more advanced systems such as the NFS-7 and its subsequent succesors, due to being encased by a thick layer of plastic. Among of the more interesting features of this device were the inner masks which decreased the chance of lense fogging.

Some civilians sought to protect themselves from the airborne HNS-Virus with the ARM Respirator, although the protection provided them was minimal at best.

Trivia

 * Despite popular believe, a gas mask has to cover the entirety of the human head in order to classify as such, thus placing supposed gas masks such as the S10 (on which this one is based), the M17, M50, and the MCU-2/P actually in the respirator, rather than the gas mask, category. Of all these, only the S10 has been correctly labelled as such.
 * The Advanced Respiratory Module was an integral part of the Enhanced Modular Body Armor system, despite the fact that the NFS-8 proved itself to be effective for use in firefighting scenarios.
