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®ASTRO®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

BREATHING AIR PRESSURE TABLE
Make sure you understand the Breathing Air Pressure table before using
this respirator.
1. Select the correct air source (column 1).
2. Confirm the part number of the air supply hose you are using (column 2) and the flow 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 specified (column 6).
Make sure air is flowing 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. Check that the capacity of the
air supply systems can provide sufficient air to all users, with a maximum of 5 users connected
simultaneously per air supply unit. In addition, could result in contaminants being inhaled as the
pressure in the helmet may become negative due to peak inhalation flow when working at very
high work rates. Low airflow will decrease the level of protection provided.
WARNING
The Apparatus must be supplied with respirable air meeting the
requirements of EN 12021, AS/NZS 1715 or Higher Quality. The moisture content of the
breathable air should controlled within the limits in accordance with EN 12021, to avoid
the air freezing the apparatus. Do not use oxygen enriched air.
