If IDLH work environments exist, the the Auto-Air™ Breather Box® option should be considered.

The Auto-Air™ filtration system was developed to provide Grade-D breathing air with full automatic reserve air in the event of either electrical failure or reduced pressure from the main air source while working in hazardous environments.

Reserve air activation occurs a 60psi and/or loss of electrical supply, the system automatically switches to the reserve air cylinder(s). Local and optional remote alarms signal the workers that the primary air system has failed and has switched to the back-up air system. The Auto-Air™ feature is offered in electric or pneumatic versions.
