The demand version of the Ultra Elite facepiece can be used as a twin-cartridge air-purifying respirator for full-face respiratory protection. The unique lens design provides a high level of peripheral and downward vision. It is available in three sizes and has large adjustment tabs that simplify wear. A choice of two facepiece materials - SoftFeel Hycar rubber or silicone - enhance wearer comfort. For improved communication, a speaking diaphragm in front of the wearer's mouth ensures clear short-range communications. A nosecup reduces lens fogging.
