The ALE (Airline Egress) Lite is a supplied airline respirator (combination pressure demand type) with a 5 or 10-minute self-contained breathing apparatus for emergency use. Should the airline supply fail for any reason, the SCBA would be employed. The ALE Lite may be used in the supplied air mode up 300 feet from the air source. The harness provides the wearer with a comfortable fit without compromising effectiveness. It is also easily removed for cleaning. The pneumatic system is designed to provide the user with a constant air supply, even in the most stressful situations. The ALE Lite includes the Panorama Nova full facepiece with true double sealing edges for a superior fit, and a speech diaphragm for clear speech communications.
