Automatic-Transfer, Added Peace-of-mind.

The Ska-Pak™ AT respirator is the most advanced pressure demand supplied air respirator from 3M™ Scott™ Fire & Safety, equipped with the added benefit of a patented, automatic, hands-free air transfer capability.

If the primary air supply to the respirator is interrupted, the air source is instantly switched to the portable air cylinder without user intervention. Upon transfer, the Vibralert tactile alarm system activates, vibrating the user’s facepiece and alerting the user that the respirator has transferred to cylinder air.

The Ska-Pak™ AT supplied air respirator is ideal for many applications, including confined space operations, hazardous materials clean-up and maintenance jobs for numerous markets, including chemical, petrochemical, oil and gas, ship building and public utilities.
