1. General information
Use of a respirator must be part of a respiratory
protection 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 System description

The SR 700 is a battery-powered particle filter fan unit
that, together with particle filter and head top - hood,
visor, welding shield, helmet with visor, half mask or
full face mask - is included in the Sundström
fan-assisted respiratory protective device systems
conforming to EN 12941 or EN 12942 and to
Sundström Powered Air Purifying Respirator (PAPR)
system conforming to AS/NZS 1716:2012.
The fan unit is to be equipped with filters, and the
filtered air is supplied through a breathing hose to the
head top. The above-atmospheric pressure then
generated prevents pollutants from the surroundings
from penetrating into the head top.
Before use, both these user instructions and those for
the filter and head top must be carefully studied.

1.2 Applications

The SR 700 can be used as an alternative to filter
respirators 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:
• Types of pollutants
• Possible occurrence of explosive atmosphere
• 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.
1.3 Warnings/limitations
Note that there can be national differences in the
regula tions for use of respiratory protective
equipment.
Warnings
The equipment must not be used
• In the power-off state. In this abnormal situation a
rapid build-up of carbon dioxide and depletion of
oxygen may occur in the head top and no protection
is given.
• If the surrounding air does not have a normal oxygen
content.
• If the pollutants are unknown.
• In environments that are immediately dangerous to
life and health (IDLH).
• With oxygen or oxygen-enriched air.
• If you find it difficult to breathe.
• If you can smell or taste the pollutants.
• If you experience dizziness, nausea or other
discomfort.
Limitations
• The SR 700 must always be used with two particle
filters.
• If the user is exposed to very high work intensity,
negative pressure 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 700 fan unit when used with this filter.
