The MACK-NFPA3 air distribution system is specifically designed for confined space fire and rescue operations. The MACK NFPA3 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.
In addition to what MACK-NFPA1 has, MACK-NFPA3 features an innovative regulator isolation-valve that allows you to use 1 or both your air sources simultaneously. It also has a high pressure CGA-347 inlet that allows uninterrupted operation from air cylinders which are truck mounted.
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.
