The 3M™ Scott™ Ska-Pak AT Supplied-Air Respirator is an advanced supplied-air system with escape cylinder, designed for confined space, hazmat, and IDLH industrial applications. This refurbished unit features an automatic, hands-free air transfer system that instantly switches from the primary air source to the onboard cylinder if supplied air is interrupted, helping reduce user stress and improve safety during emergencies.

The Ska-Pak AT is equipped with an E-Z Flo pressure-demand regulator with first-breath activation and low breathing resistance for reduced user fatigue. Upon transfer to cylinder air, the integrated Vibralert tactile and audible end-of-service alarm alerts the user that egress is required. Available with padded nylon, fire-resistant Kevlar®, or an integrated NIOSH-approved full-body fall protection harness, the Ska-Pak AT supports multiple cylinder pressures and 3, 5, 10, or 15-minute escape options, delivering flexible and dependable protection for demanding industrial environments.
