A PAPR is a powered air purifying
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.
Depending on the headgear chosen,
certain powered air systems also provide
head, eye and face protection. Powered
air systems are available as face-
mounted, helmet-mounted and belt-
mounted configurations. PAPR systems
include a headpiece, a breathing tube,
motor-blower unit, filters, and/or a
cartridge and battery.

Supplied Air Respirators

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 powered and supplied air respirators, review pages 15-16 of this catalog.
* 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.
