The MACK-NFPA1 air distribution system is specifically designed for confined space fire and rescue operations. The MACK NFPA1 has 2 separate manifold / regulator systems, both of which are supplied with 2 SCBA connecting whips. In case one regulator fails, the rescue operation can be executed with the stand-by regulator system.
1 or 2 SCBA cylinders may deliver air into the system. The regulator for low-pressure provides 0 to 125 psi for a 4-outlet respirator manifold. The alarm whistle for low-pressure & a 6V DC lamp illuminates the interior of the case and are included as standard equipment.
