A PAPR is a powered air respirator system that uses a
fan to deliver filtered air into a hood, helmet or full
facepiece. There are many different PAPR
configurations available. Depending on the working
environment, select the PAPR style that best meets
your needs.
Powered air systems also provide head, eye and face
protection. They are available as face-mounted, helmet-
mounted and belt-mounted configurations. PAPR
systems include a headpiece, often a breathing tube,
motor-blower unit, filters, a cartridge and battery.

Supplied Air Respirators are designed to deliver
clean air to the worker. The air* can be supplied from a
high pressure compressor, low-pressure pumps, or
cylinders (bottled air). This clean, breathable air can be
delivered to hoods, helmets, full facepieces, half
facepieces and loose-fitting facepieces.
Supplied air respirators offer many features over
traditional respiratory protection such as:
• Cooling or heating incoming air
• Fit testing only required on tight-fitting facepieces
• Low maintenance
Supplied air systems are a good way to help increase
comfort and protection.
For an overview of headgear used with supplied air
respirators, review pages 12-13 of this document.
*It is the employer’s responsibility to ensure that the compressed air used with any supplied air system meets the requirements for at least
Grade-D breathing air per the Compressed Gas Association Commodity Specification G-7.1-1997 in the U.S. In Canada refer to CSA
Standard Z180.1 table for the quality of compressed breathing air.
