What sets apart positive and negative pressure gasmasks?
A positive pressure respirator acts as a shield, keeping contaminants from seeping in around the face seal. In contrast, negative pressure means that during inhalation, the air pressure inside the mask is lower than the air pressure outside.
The AvonFM54, on the other hand, is a versatile solution. It seamlessly operates in both negative and positive pressure modes (APR, SCBA, CCBA, and PAPR).
Thanks to the robust lever on the VREU (Variable Resistance Exhalation Unit), you can switch between these modes effortlessly, all without having to remove the optional VPU (Voice Projection Unit) or compromising on protection.
It’s a game-changer in respiratory safety!
The Elite Avon Protection FM54™ is also now available in our online store.
