The Auto Air IDLH filtration system is engineered to supply breathing air (Grade D) with full-automatic emergency reserve air in case of failures or reduced main air source pressure while performing job duties in hazardous environments. The reserve-air activation triggers at 60 PSI and / or electrical supply loss, the system will automatically switch to your reserve air cylinder. Local & remote (optional) alarms signal personnel of primary air system failure & that the system has switched to back-up.
Note - IDLH conditions require pressure demand respirator usage with a minimum 5 min. escape cylinder.
* When ordering, please specify .25 inch Hansen or Schrader style fittings
