Technical Specification - Sundstrom SR 500 Instrucciones De Uso

Limitations
• The SR 500 must always be used with two particle
filters or two combined filters or a combination of two
gas filters of the same type and two particle filters.
• If the user is exposed to very high work intensity, a
partial vacuum may occur in the head top during the
inhalation phase, which may involve the risk of
leakage into the head top.
• The protection factor may be reduced if the
equipment is used in surroundings in which high
wind speeds occur.
• Be aware that the breathing hose might make a loop
and get caught up by something in your surrounding.
• Never lift or carry the equipment by the breathing hose.
• The filters must not be fitted directly to the head top.
• Only use Sundström filters.
• The user should take care not to confuse the
markings on a filter to standards other than EN 12941
and EN 12942 with classification of the SR 500 fan
unit when used with this filter.

2. Technical specification

Air flow rate
During normal operation, the air flow rate is at least 175
l/min, which is the manufacturer's recommended mini-
mum flow rate or MMDF.
On boosted operation, the air flow rate is up to 240 l/min.
The automatic flow control system of the fan unit main-
tains these flows constant throughout the operating time.
Batteries
STD, Standard, 14.8 V, 2.2 Ah, lithium-ion.
HD, Heavy Duty, 14.8 V, 3.6 Ah, lithium-ion.
• The charging time for the STD battery is about 1.5 h.
• The charging time for the HD battery is about 2 h.
• The cycling life is about 500 full cycles.
• The battery do not need to be discharged before it is
charged.
Operating times
The operating times may vary with the temperature, and
the condition of the battery and filters.
The table below gives an indication of the expected ope-
rating times under ideal conditions.

of manufacture. However, note that the battery must be
charged at least once a year.

3.3 Battery
New batteries must be charged before they are used for
the first time. See 3.5 Assembly.
3.4 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 (PAPRA1BE2K1-
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 pro-
tection against all types of particles, both solid and li-
quid. The SR 510 can be used separately or combined
with a gas filter. The SR 710 cannot be combined with a
gas filter. The particle filters can be used with the same
pre-filter holder as the one used with the Sundström
half- and full face masks. In these cases, the standard
pre-filter holder of the fan is excluded. See 5. Parts list.
