The Ultra Elite and Ultravue Facepieces feature an inhalation check valve and exhalation valve that work together to help prevent exhaled air from entering the mask-mounted regulator and contaminating the internal regulator components. The result is improved regulator reliability and durability, and reduced frequency maintenance. The facepieces' speaking diaphragms help provide intelligible short-range voice communications, while the optional ESP Mask Communications System provides voice amplification and/or interface with two-way radios. As an option, the Ultra Elite and Ultravue Facepieces are also available with the EZ-Don Facepiece Harness. It offers the same fit and comfort as the standard rubber harness, but provides a rapid donning and simplified method of adjustment.
