Powered Air
The RPB® Z-LINK® Respirator, when properly tted and used with all required components,
including the Breathing Tube Assembly and the 03-901 RPB® PX4 AIR® Powered Air Purifying
Respirator, is a NIOSH approved powered air purifying respirator with an assigned protection
factor of 1000. As such, it signicantly reduces, but does not completely eliminate, the breathing
of contaminates by the respirator wearer. Specic protection depends on the lter selected for
use in the RPB® PX4 AIR® PAPR (see PX4 AIR® Instruction Manual).
Supplied Air
The RPB® Z-LINK® Respirator, when properly tted and used with all required components,
including the Breathing Tube Assembly, 03-101 Constant Flow Valve or the 03-500 C40™
Climate Control Device, and RPB® Breathing Air Line is a NIOSH approved respirator with an
assigned protection factor of 1000. As such, it signicantly reduces, but does not completely
eliminate, the breathing of contaminates by the respirator wearer. Use with an airline lter, such
as the 04-900 RPB® RADEX® Airline Filter. Specic protection depends on the setup of the
airline lter (see the RPB® RADEX® Instruction Manual).
HAZARD LIMITATIONS
The RPB® Z-LINK® Respirator is NOT FOR USE if:
 In atmospheres immediately dangerous to life or health (IDLH).
 Wearer cannot escape without the aid of the respirator.
 Atmosphere contains less than 19.5% oxygen.

AIR SOURCE, FITTINGS, AND PRESSURE
AIR SOURCE
Powered Air
Check that the contaminated area is within the limits of use for a Powered Air Purifying
Respirator and determine the type of contamination. Once the contamination level has been
conrmed you can then determine the lter cartridge to be used for the application, to make sure
that you are sufciently protected. Make sure that the area is well ventilated and that regular air
samples are taken to conrm the atmosphere stays within the levels recommended by OSHA
and other governing bodies. Follow the PX4 AIR® PAPR Instruction Manual for more details.
Supplied Air
Locate the air source in a clean air environment, always use a lter on the inlet of your air source.
Make sure the air source is somewhere that vehicles, forklifts, and other machinery are not
running near the air inlet, as this will cause carbon monoxide to be drawn into your air supply.
Always use suitable after coolers/dryers with lters and carbon monoxide alarms to ensure clean
breathable air is supplied at all times. A Radex® Airline Filter (04-900) and a GX4® Gas Monitor
(08-400) are recommended. The air should be regularly sampled to ensure that it meets Grade
D requirements.
AIR QUALITY
This respirator must be supplied with clean breathable air at all times. Breathable air must at
least meet the requirements for Type 1 gaseous air described in the Compressed Gas Association
Commodity Specications G.7.1 (Grade D or higher) and as specied by Federal Law 42 CFR
84, subpart J.84.141(b) and 29 CFR 1910.134 (i). The RPB® Z-LINK® does not purify air or lter
contaminants. A carbon monoxide monitor must be used at all times.
Do not connect the respirator’s air supply hose to nitrogen, toxic gases,
inert gases or other unbreathable non-Grade D air sources. Check the
air source before using the respirator. This apparatus is not designed for use with mobile air supply
systems i.e. cylinders. Connecting the supply hose to a non-breathable air source will result in
serious injury or death.
BREATHING AIR SUPPLY HOSES AND FITTINGS
RPB® air supply hoses and ttings must be used between the point of attachment and the
respirator breathing air connection at the wearer’s belt. The hose sections must be within the
correct length and the amount of sections must be within the number specied in the breathing air
pressure table on page 14.
BREATHING AIR PRESSURE
The air pressure must be continually monitored at the point of attachment. Air pressure must be
read from a reliable pressure gauge whilst the respirator has air owing through it.

Make sure you understand the Breathing Air Pressure table before using
this respirator.
1. Use the correct air source. Do not use an ambient air pump, as it does not supply enough
pressure (column 1).
2. Conrm the part number of the air supply hose (column 2) and the ow control device (column
3) you are using.
3. Check your RPB® Safety Air Supply Hose is within the correct length (column 4) and the
correct number of hose sections (column 5).
4. Set the air pressure at the point of attachment within the range specied (column 6).
Make sure air is owing through your respirator when setting the air pressure.
Failure to supply the minimum required air pressure at the point of attachment for the length
of air supply hose will decrease the level of protection provided. In addition, could result in
contaminants being inhaled as the pressure in the helmet may become negative due to peak
inhalation ow when working at very high work rates. Low airow will decrease the level of
protection provided.
If the Breathing Air Lines and Flow Control Device have RZ
™ ttings, they will only attach to other
RZ™ ttings. They will not work with Universal Couplers. Do not modify air line ttings. RZ
™ ttings
prevent connection to unsafe air sources.
