Mask-Mounted Regulator (MMR)
The PremAire System features a pressure-demand regulator mounted at the facepiece.
MMR maintains slight positive pressure within the facepiece while regulating and reducing air
supply from NIOSH/MSHAapproved range of 60-100 psig of breathable pressure.
The result is a low-profile, high-performance unit that quickly responds to a user’s changing breathing requirements.
Unit also features a second-stage regulator bypass system and shutoff button, making it easier for users to deactivate the second-stage regulator.
The PremAire System features the Firehawk® MMR. Offered as both push- and slide-to-connect versions, the
Firehawk MMR’s design keeps the facepiece profile to a minimum while offering almost 100% field-of-vision.
MSA also offers the Solid-Cover Firehawk MMR for users not needing a purge button.
Solid-Cover Firehawk MMR operates the same as the original Firehawk MMR.
