The Scott Vision AMS Silicone is offered in 3 different sizes and will accommodate a wide range of facial shapes and sizes. The facemasks are positive pressure and feature a Silicone outer mask and a TPE ori-nasal inner mask. The facemask visor is multi curvature and made of a scratch and impact resistant polycarbonate material with a flame-retardant coating and provides excellent panoramic vision. The visor is held in place by two U-shaped clamps. The mask allows the wearer to wear integrated spectacle frames, without compromising the facemask seal. The facemask is available with either a five-point fully adjustable neoprene strap style harness or a two-point adjustable polyester net style harnesses.
The facemask is a true dual use facemask with an exhale valve that can operate in a true negative pressure mode for use with filters and powered air systems and then when a DV is attached via a bayonet adaptor it switches automatically to a positive pressure exhale valve. This is all done via the front fitting of the facemask. An option of an additional right quickfit port is available to take a communications interface if required. A speech diaphragm is mounted at the left of the mask to offer unimpeded speech transmission.
