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 confirmed you can then determine the filter cartridge to be used for the application,
to make sure that you are sufficiently protected. Make sure that the area is well ventilated
and that regular air samples are taken to confirm the atmosphere stays within the levels
recommended by governing bodies. Follow the PX4 AIR
®
PAPR Instruction Manual for more
details. The Manufacturer Minimum Designed Flow is 170 l/min, Speed 1 - 10 hours, Speed
2 - 7 hours, and Speed 3 – 6 hours when used with the 03-895 P3 filter. The Manufacturer
Minimum Designed Flow is 170 l/min, Speed 1 - greater than 4 hours, Speed 2 and Speed 3
are not recommended when used with the 03-995 A2P3 filter.
Supplied Air
Locate the air source in a clean air environment, always use a filter 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 filters 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 EN 12021 (AS/NZS 1715) requirements.
AIR QUALITY
This respirator must be supplied with clean breathable air at all times. Breathable air must at least
meet the requirements for EN 12021 (AS/NZS 1715). The RPB
®
Z-LINK
®
does not purify air or
filter 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-EN 12021 (AS/NZS 1715) 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 fittings 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 specified in the
breathing air pressure table on page 15.
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 flowing through it.
