PremAire® Cadet Supplied-Air
Principles of Operation

  The PremAire Cadet Respirator is a pressure-demand device, meaning it delivers
respirable air to the user "on demand." As such, it maintains a slight positive pressure of
air inside the facepiece -- whether the wearer is inhaling or exhaling -- to prevent
contaminants from entering the facepiece, should any slight face-to-facepiece seal
leakage occur.
Because the unit is a pressure-demand device, it can be used with a large, compressed air
cylinder or a bank of cylinders set up in cascade fashion. For longer-duration air supplies,
the respirator also can be used with a compressor that delivers respirable air to the user
within the NIOSH-approved pressure range.

Approvals & Standards

  PremAire Cadet Respirators have received National Institute for Occupational Safety and
Health (NIOSH) certification for use in atmospheres not immediately dangerous to life or
health (Non-IDLH).*
Units are approved for use with an operating inlet pressure of 60-100 psig, and only when
used with MSA Air-Supply Hose. PremAire Cadet Respirators require a source of
compressed air conforming to at least 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 acverse physiological symptoms after
prolonged exposure.

  The PremAire Cadet respirator is a pressure-demand, Type C, supplied-air respirator
designed to provide users with a choice of respiratory protection options. Available in two
models, the respirator can serve as a basic supplied-air device or, with the Duo-Twin
option, function as a combination air-line/air-purifying respirator. Designed for a variety of
applications, PremAire Cadet respirators are well suited for use in the chemical and
petrochemical processing industries, utilities work, general industry and asbestos and lead
paint abatement. They also can be used for pharmaceutical applications and for
hazardous materials clean-up work in non-IDLH (Immediately Dangerous to Life or Health)
