The Auto-Air™ filtration system was developed to provide Grade-D breathing air with full automatic reserve air for use in Immediately Dangerous to Life or Health (IDLH) work locations. In the event of electrical failure or reduced pressure from the primary air source, reserve air activation automatically switches to the reserve air cylinder(s). An alarm signals the worker(s) the primary air system has failed and switched to the back-up air system.

NIOSH requires the use of a 5 minute airline escape respirator when working in IDLH environments.
Our Auto-Air™ feature does not replace the NIOSH requirement. Some work environments may require a 30 minute (or longer) airline escape method to safely egress the hazardous area. This situation would require the use of an Auto-Air™ Breather Box® or Auto-Air™ Cart with reserve air cylinder.
