Air Systems International MACK-5500™ Multi-Air Command Kit


The MACK-5500™ (Multi-Air Command Kit) Series retains all the features and functionality of a standard MACK unit, with the added benefit of higher incoming pressures for today’s SCBA’s and mobile cascade systems. The newly developed breathing air regulators have been designed to handle the rigors of cycling inlet pressures ranging from 500 psi to 5,500 psi while precisely maintaining outlet pressures and flow to the connected respirators.

With a “set and forget” outlet control and easily identifiable and manageable air circuits, the operating attendant is now free to manage and cycle the various input sources as needed.
