The Auto-Air™ Compressor System Package provides automatic back-up air for up to 3 workers in the event of compressor failure. An optional 60 or 87cf cylinder can be installed on the compressor frame for additional egress air. Included in the package are the Auto-Air™ Breather Box® model BB30-COAA, the TA-3EA compressor with a CGA-347 high pressure reducing regulator, and primary and secondary hoses. NIOSH recommends using a 5 minute airline escape respirator for IDLH environments, but certain work conditions may require longer air supplies. This compressor is not compatible with constant flow respirators or Vortex cooling tubes.
