MSAs new AirHawk II Air Mask is a cost-effective option that offers many choices not available with any other industrial air mask. The AirHawk II Air Mask offers either the Ultra Elite® Facepiece or new industrial Advantage 4000 Facepiece. The Advantage 4000 Facepiece provides adapters for Twin-Cartridge Respirator conversion (using Advantage Cartridges) or an RD40 Facepiece. The AirHawk II Air Mask now incorporates as standard the same Audi-Larm Audible Alarm End-of-Service-Time-Indicator (EOSTI) as the proven fire service FireHawk® M7 Air Mask. Air Hawk II Air Masks also offer both low-pressure and high-pressure versions.
