Principles of Operation :
The PremAire Respirator is a full-face, pressure-demand, Type-C
supplied-air respirator with a patented waist-mounted manifold
that gives it incredible flexibility. Featuring five individual
ports, the manifold makes it possible to add any of these
capabilities:
Supplied-air respirator with emergency-escape air cylinder for
egress from IDLH atmospheres.
Combination supplied-air/air-purifying respirator, which lets
you move freely from station to station without being tethered
to an air-supply hose, yet still be protected by the device's
air-purifying capability.
Supplied-air respirator with dual-supply capability -- an MSA
exclusive that eliminates the need to drag long lengths of
air-supply hose around the work area.
Supplied-air respirator with Vortex tube, which provides body
cooling, or warming, whenever protective clothing is required.
No matter which option you choose, you'll find that the PremAire
System provides dependable protection, engineering excellence
and cost-effective versatility.
Approvals & Standards :
The PremAire Supplied-Air Respirator System has received
National Institute for Occupational Safety and Health (NIOSH)
certification for use in atmospheres not immediately dangerous
to life or health (Non-IDLH)*. When equipped with the
emergency-escape cylinder option and the Ultravue or Ultra Elite
pressure-demand facepieces, the PremAire System is also approved
for use in IDLH atmospheres.
WARNING: Duo-Twin Facepiece-equipped respirators are not
approved for IDLH applications, even if equipped with the
emergency-escape cylinder option.
Units are approved for use with an operating inlet pressure of
60-100 psig, and only when used with MSA Air-Supply Hose. See
special use section of instructions for specific use
limitations. The PremAire System requires a source of compressed
air conforming to at least Quality Verification Level (Grade) D
Compressed Gas Association, Inc., Commodity Specification for
Air, G-7.1.
*Not immediately dangerous to life or health is defined in 42
CFR Part 84 as any hazardous atmosphere which may produce
physical discomfort immediately, chronic poisoning after
repeated exposure, or acute adverse physiological symptoms after
prolonged exposure.

Product Information :
The basic PremAire respirator includes a patented manifold and
choice of four upgrade options. An escape cylinder option
permits emergency escape from Immediately Dangerous to Life and
Health (IDLH) atmospheres. A Dual-Supply option lets workers
connect from one pressurized continuous air source to another
without losing continuity of air flow. A Duo-Twin option
converts the respirator into a combination
supplied-air/air-purifying device. This allows workers in non-IDLH
atmospheres to move freely from station to station without being
tethered to an air-supply hose. A vortex tube option delivers
whole-body temperature control for added worker comfort
