AIR SOURCE, FITTINGS, AND PRESSURE
AIR SOURCE
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 and 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 and AS/NZS 1715. The RPB
®
NOVA 1
®
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 non-breathable air sources. Check the air source
before using the respirator. This apparatus is not designed for use with mobile air supply systems
e.g. 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
®
breathing 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 13.
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.
