2.4 Filters
The choice of filters/combined filters depends on
factors such as the type and concentration of
pollutants. The fan unit may be used with only particle
filters or with a combination of particle filters and gas
filters.
The following filters are available for the SR 500:
• Particle filter P3 R (PAPR-P3), model number SR
510. Used with an adapter. Two filters are supplied
with the fan. Can be combined with a gas filter.
• Particle filter P3 R (PAPR-P3), model number SR
710. Provided with a thread, and there is no need
for an adapter. Cannot be combined with a gas
filter.
• Gas filter A2 (PAPR-A2), model number SR 518.
Shall be combined with a particle filter.
• Gas filter ABE1 (PAPR-ABE1), model number SR
515. Shall be combined with a particle filter.
• Gas filter A1BE2K1 (PAPR-A1BE2K1), model
number SR 597. Shall be combined with a particle
filter.
• Combined filter A1BE2K1-Hg-P3 R (PAPR-
A1BE2K1-Hg-P3), model number SR 599.
Note:
• The filters used must be of the same type, i.e. two
P3 R (PAPR-P3) or two A2P3 R (PAPR-P3), etc.
• When filters are changed, both filters/combined
filters must be changed at the same time.
• The particle filter must always be used - either
separately or in combination with a gas filter.
Particle filter P3 R (PAPR-P3)
Sundström markets only particle filters of the highest
class P3 R (PAPR-P3). Two models are available for
fan SR 500, i.e. SR 510 and SR 710. The filters provide
protection against all types of particles, both solid and
liquid. The SR 510 can be used separately or
combined with a gas filter. The SR 710 cannot be
combined with a gas filter. The SR 710 can be used
with the same pre-filter holder, SR 5153, as the one
used with the Sundström face masks. In these cases,
the standard pre-filter holder of the fan is excluded.
See 5. Parts list, below.
Gas filters A, B, E, K, Hg
A protects against organic gases and vapours, e.g.
solvents, with a boiling point of more than +65 °C.
B protects against inorganic gases and vapours, e.g.
chlorine, hydrogen sulphide and hydrogen cyanide.
E protects against acidic gases and vapours, such as
sulphur dioxide and hydrogen fluoride.
K protects against ammonia and certain amines, e.g.
ethylene diamine.
Hg provides protection against mercury vapour.
Warning. Maximum use time 50 hours.
The gas filters must always be combined with particle
filters P3 R (PAPR-P3). Press the filters together so
that the arrows on the particle filter point towards the
gas filter. Fig. 14.
Combined filter SR 599, A1BE2K1-Hg-P3 R,
(PAPR-A1BE2K1-Hg-P3)
Protects against ABEK-P3 R (PAPR-ABEK-P3)
pollutions as described above and in addition against
Hg, mercury vapour. When used to protect against
mercury vapour the period of use is limited to 50
hours.

Pre-filter
The pre-filter protects the main filter against
excessively fast clogging. Fit in the pre-filter holder,
which protects the main filters against handling
damage. Fig. 12.
N.B. The pre-filter can serve only as a pre-filter. It can
never replace the particle filter.
Read carefully the user instructions accompanying the
filters.
2.5 Assembly
a) Battery
On delivery, the battery fitted in the fan unit is
provided with protective tape over the terminals.
Remove the battery and remove the tape. Proceed as
follows:
• Place the fan upside down. Grip the fan with one
hand, with the thumb placed over the battery.
• The battery cover locks the battery. Raise the cover
a few centimetres, push with the thumb resting on
the battery and withdraw the battery. Fig. 3.
• Check that the mains voltage is between 100 V and
240 V.
• Connect the battery to the battery charger. Fig. 2.
• Connect the charger plug to a wall socket.
The charger carries out charging automatically in
three stages:
1. Orange LED. The battery is being charged at
constant, maximum charging current up to approx.
80% of battery capacity.
2. Yellow LED. The battery is being charged to full
capacity at constant voltage and gradually decreasing
charging current.
3. Green LED. The battery is fully charged and the
charging current is switched off.
• When charging has been completed, pull the plug
out of the socket before separating the battery from
the charger.
• Push the battery back into the battery compart-
ment. Check that the battery has been pushed in
as far as it will go and that its lock is operative.
Warning!
• Always recharge the battery before it has become
fully discharged.
• The charger may be used only for charging the
batteries for the SR 500.
• The battery may be charged only with a genuine
Sundström charger.
• The charger is designed only for use indoors.
• The charger must not be covered while it is in use.
• The charger must be protected against moisture.
• Never short circuit the battery.
• Never try to dismantle the battery.
• Never expose the battery to a naked flame. There is
risk of explosion/fire.
