1. General information
The SR 500 is a battery-powered fan unit that, together
with filters and head top, is included in the Sundström
fan-assisted respiratory protective device systems
conforming to EN 12941 or EN 12942 and to Sund-
ström Powered Air Purifying Respirator (PAPR) system
conforming to AS/NZS 1716:2012.
Before use, both these user instructions and those for
the filter and head top must be carefully studied.
The fan unit is to be equipped with filters, and the filte-
red air is supplied through a breathing hose to the head
top.
The above-atmospheric pressure then generated pre-
vents pollutants from the surroundings from penetra-
ting into the head top.
Use of a respirator must be part of a respiratory protec-
tion program. For advice see EN 529:2005 or AS/NZS
1715:2009.
The guidance contained in these standards highlights
important aspects of a respiratory protective device
program but does not replace national or local
regulations.
If you feel uncertain about the selection and care of the
equipment, consult your work supervisor or get in
touch with the sales outlet. You are also welcome to get
in touch with the Technical Service Department at
Sundström Safety AB.
1.1 Applications
The SR 500 can be used as an alternative to filter respi-
rators in all situations for which these are recommended.
This applies particularly to work that is hard, warm or of
long-duration.
When selecting filters and head top, the following are
some of the factors that must be taken into account:
• Possible occurrence of explosive atmosphere
• Types of pollutants
• Concentrations
• Work intensity
• Protection requirements in addition to respiratory
protective device
The risk analysis should be carried by a person who has
suitable training and experience in the area.

itself as this would either obstruct the air flow or
cause failure to achieve a proper seal.
• Grip the flow meter tube with the other hand so that
the tube points vertically upwards from the bag.
Fig. 30.
• Read the position of the ball in the tube. This should
hover at a level with or slightly above the upper
marking on the tube, (175 l/min). Fig. 31.
If minimum flow is not achieved, check that
- the flow meter is held upright,
- the ball moves freely,
- the bag seals well around the hose.
Checking the alarms
The equipment is designed to provide a warning if the air
flow is obstructed.
• Provoke an air flow stoppage by gripping the top part
of the bag or by shutting off the flow meter outlet.
Fig. 32.
• The fan unit should then initiate alarms by sound, light
signals and vibrations.
• If the air is again allowed to flow, the alarm signals will
automatically cease after 10-15 seconds.
3.8 Putting the equipment on
After the filters have been fitted, a performance check
has been carried out and the head top has been con-
nected, the equipment can be put on. Before putting it
on, read the user instructions for the head top.

The fan unit contains a circuit board with electronic
components, a small proportion of which comprise toxic
substances. The battery contains no mercury, cadmium
or lead, and is therefore not regarded as environmentally
harmful waste. The plastic parts are marked with the
material code. For proper handling, collection and recy-
cling, worn-out fans should be handed in to a recycling
centre. Contact the local authorities for information on
the location of your nearest recycling centre.
Recycle in accordance with local regulations. Proper re-
cycling of the product contributes to efficient use of the
natural resources.
