Breathing protection
Breathing protection Sundström Safety AB was founded in 1926 by Ivan Sundström
who was a mining engineer and realized at an early stage
the need for protecting the eyes and lungs of miners.
The company and its products were developed further by his son Per, who also studied at
the Technical Academy (now Faculty of Art). His art studies included analysis of subjects
such as the anatomy of the human body. The understanding of human face forms laid the
foundations for the design and properties of face masks. A good respiratory protection devi-
ce must be simple and comfortable to use. In 1962, Per Sundström also presented the first
modern protective mask, which was made of rubber and was of anatomic design. The first
silicone mask was launched in 1989.
Our aim is to protect people against polluted air. It was this concern that prompted our
grandfather to begin producing protective masks 80 years ago. We then carried this task
through into the 21st century. This is why we are not content with merely conforming to the
demands of the authorities. We do our utmost to make our
products as good and efficient as present-day technology
enables us to do. During the past 35 years, Sundström Safety
has invested vast resources into product development. The
objective has been to create an expandable and flexible
product range. We can now present our complete system of
masks, filters and accessories for all applications occurring
in the market. Although we are very pleased with our present
products, we continue to pursue our product development work.
We always endeavour to offer the best possible protection.
When our grandfather founded his company, he would never
have imagined how it would grow into todays export-orien-
ted company. On the other hand, he undoubtedly hoped the
company would live on and stay in the family. His wishes have
been met and will continue to be met in the future.
Per Sundström passed away in December 2004, and the third
generation of the family continues to run the company in the
same spirit.

Protecting people from polluted air
2 Respiratory protective devices
Many harmful substances, such as gases and particles, occur in our modern
world. At work and in leisure activities, we may be exposed to serious threats.
Respiratory protective devices are classified
into two main groups
1000 particles/cm
3
(outside the protective device)
50 particles/cm
3
(inside the protective device)
= protection factor of 20
What is Assigned Protection Factor APF?
The assigned protection factor (APF) is a workplace measurement where the protective device has been tested
in real working situations on workers. This factor is normally lower than laboratory tests (nominal protection
factor) as the test also covers the human factors (i.e. individual fit, wear time, etc.). All respiratory devices
within each area (i.e. half masks, full-face masks, hoods) is therefore given the same APF in its group. The
purpose of the APF is to be a guideline for selection of respiratory protective equipment in different hazardous
environments (to select the right protection level for a specific working situation based on a risk assessment)
Example:
A half mask with filter has an APF of 20, (the air inside the mask is 20 times cleaner than the surrounding air),
and can be used in concentrations of up to 20 times OEL. Note that it shall not be used in environments where
there is Immediate Danger to Life and Health (IDLH). Check national recommendations!

How effective is the protection?
The protection factor is a measure of the efficiency of the respiratory protective device. As an example, if the
content of a substance on the inside of the mask is one twentieth of what it is in the ambient air, the respiratory
protective device is said to have a protection factor of 20.
Example:
Filtering devices
Breathing apparatus
The breathing air is purified as it flows
through a filter.
(May be used only if the oxygen content
of the ambient air is normal).
Compressed air-fed.
Self-contained breathing apparatus
(air in a cylinder). Half masks/Full face mask
There are half masks that enable the user to perform
strenuous work during parts of the day, or for work
during the whole of day. In their design, Sundström
half masks are known for having an excellent fit, high
protection level and very low breathing resistance.
With high concentrations of air pollutants, a full face mask
is often recommended. The Sundström full face mask
gives very good protection in all situations in which filter
protection is used.
All masks in Sundströms programme use the same
range of filters, and can be combined efficiently and
economically for each working situation.
Filter protection shall never be used in conditions that
are Immediately Dangerous to Life and Health (IDLH).
The
SR 100 half mask is made of silicone and is available
in two sizes, S/M and M/L. The mask is equipped with
two exhalation valves, which ensures very low exhalation
resistance. Valve covers with baffles effectively protect
the exhalation membrane against dust and paint mist. The
easily adjustable elastic head harness is designed as a
V-shaped loop and has a large, dished crown plate, which
contributes towards a comfortable and secure fit. The
SR 307 compressed air attachment can be connected.
Tested in accordance with prEN 140:1996
The
SR 90-2 half mask is made of thermoplastic
elastomer (TPE) in two sizes, S/M and M/L. The mask
is equipped with two exhalation valves, which ensures
very low breathing resistance. The easily adjustable
elastic head harness is designed as a V-loop and has a
large, dished crown plate, which contributes towards a
comfortable and secure fit. The SR 307 compressed air
attachment can be connected.
Tested in accordance with prEN 140:1996
Full face mask SR 200 is intended for use when maxi-
mum safety and good breathing comfort are required. The
full face mask is used with the same simple filter system
and compressed air attachment as our half masks. The
material and pigment in the faceblank are FDA and BGA
approved for foods, which minimises the risk of contact
allergies. All exposed plastic parts are made of polyamide.
The mask has two exhalation valves for minimum exha-
lation resistance, and an easily adjustable textile strap.
Some of the inhalation air is guided via the screen disc to
prevent it misting from condensation. The mask has a very
low weight, only 450 grams.
Tested in accordance with EN 136:1998

4 Masks/Accessories
The
SR 345 protective hood is intended for use together
with Sundström half masks with filters or with the SR 307
compressed air attachment, or together with the SR 90
Airline. Made of chemicals-resistant, PVC coated fabric,
it protects against splashing and dripping of most sub-
stances. The hood is fitted so that the exhalation valves
are outside the hood, which reduces the risk of misting
by condensation on the visor. The SR 346 protective
hood offers the same benefits and is of similar design to
the
SR 345, but is extended so that it covers the top part
of the users body.
The
SR 64 short-duration protective hood fits Sundström
half masks. Protects the head and hair against dust
during grinding and work that gives rise to splashing,
such as in high-pressure washing or spray painting.
Made of Tyvec® and equipped with a PVC visor.
Storage box SR 230 is used for storing Sundström half masks
and filters. The box protects the equipment against dirt and
physical damage.
Storage bag SR 339 is made of durable and pliable synthetic
material. Designed to accommodate a Sundström half mask
and filters.
Storage box SR 344 is intended for storage of respiratory
protection products. The lid is made of blue transparent poly-
propylene, which makes it possible to check the contents. The
box is also suitable for wall mounting.
The
service kit for the SR 100 contains harness, set of mem-
branes, pre-filter holder and protective caps. Also available for
the SR 90-2.
Adapter SR 280-3 Intended for fitting to the SR 200 full-face
mask and to masks with EN 148-1 thread to enable Sundström
filters to be used. Tested in accordance with EN 136:1989.
Cleaning wipes SR 5226 for daily cleaning of the mask.
The
labelling system for Sundström masks simplifies their use.
