SR900 modular respirator — HOW TO…

About your SR900 respirator:

What is it?

The SR900 is a half-face respirator that covers

your nose and mouth, giving you effective

breathing protection using filters or supplied air.

The front of the face-piece has a bayonet fitting

for filters or hoses. The mask body has two

exhalation valves, and a head harness for holding

the respirator securely against your face.

When you breathe in, the air comes into the

mask through the filter or from a source of clean

air. When you breathe out, the air goes out

through the exhalation valves. If your mask is

properly fitted, no outside air leaks into the

mask as you breathe.

What makes the SR900 different?

Unlike other half face respirators, the SR900 has

a modular front attachment that lets you

connect not only filters, but also breathing hoses

leading to supplied air, or a battery-powered fan

unit, or a remote filter holder worn on a waist

belt around your back.

Why modular?

Because the SR900 can be connected to so many

other sources of clean air, it lends itself to many

more work situations and work environments

than a mask that only uses filters.

Single and twin hose

You have a choice of single or twin hose

connection to various devices. You may find the

twin hose even easier to breathe through. On

the other hand, the single hose may be simpler

to keep out of the way as you work.

Use without a hose

The simplest connection option is to attach a

filter holder directly to the mask through the

bayonet fitting. In this way, the SR900 works like

any conventional half-face mask with filters.

Connect to SR500 PAPR

Connecting the SR900 to The Sundström SR500

PAPR (Powered Air-Purifying Respirator) makes

the work of breathing easier, as it is the fan unit

— not your lungs — that draws the

contaminated air through the filters.

You can use a single or twin hose to connect to

the SR500 PAPR (with gas or particle filters or

both).

Connect to SR700 particle PAPR

Connecting the SR900 to The Sundström SR700

particle PAPR works in the same way as

connecting to the SR500 PAPR (see above).

However, you can only use particle filters with

the SR700.

Connect to remote filter holder

You may benefit from using the remote filter

holder worn on a waist belt around your back,

away from pollutants, heat, sparks, spray or

splashes that may occur in front of you while you

work.

By using the remote filter holder, you also give

the face-piece a very shallow profile that fits

comfortably inside most welding shields.

Connect face-piece directly to SR507 supplied-

air regulator

Connecting the SR900 respirator to a positive-

pressure air supply from a compressor or pump

raises the protection level significantly.

By using the Sundström SR507 regulator, you can

connect the breathing hose directly between the

regulator on your waist and the bayonet fitting

on the face-piece.

In this configuration, only the single breathing

hose can be used.

Connect face-piece to SR307 supplied-air

regulator through filter adapter

Connecting the SR900 respirator to a positive-

pressure air supply from a compressor or pump

raises the protection level significantly.

By using the Sundström SR307 regulator and the

SR900 filter attachment, you can connect the

regulator’s breathing hose to the face-piece

through the adapter.

Does size matter?

The TPE (Thermo-Plastic Elastomer) material in

the mask is so soft and pliable that it will fit

almost anybody. But people’s faces vary in many

ways, not only in size but also in the shape of the

cheekbones, nose and chin.

The SR900 comes in three sizes: Small, Medium

and Large. One of them will fit your head better

than the other and feel more comfortable and

stable on your face.

The mask size may also influence the wear of

other safety equipment, such as spectacles,

goggles, ear muffs and face shields or visors.

Make sure you try on your mask together with

other protective equipment you normally wear.

Where can the SR900 be used with filters?

Your SR900 half face respirator can be fitted with

particle (dust) filters, gas filters, or combined

dust and gas filters. Provided you are using the

correct filters, your half mask can be used for:

•Nuisance dust

•Harmful dust

•Gas and vapour

•Viruses and bacteria

•Mould and fibre

This goes for all configurations where filters are

used with the SR900:

•Filter directly attached to mask

•Remote filter holder

•SR500 PAPR fan unit with gas and/or

particle filters

•SR700 PAPR fan unit with particle filter

only

IMPORTANT: filter choice depends on the type

of hazard.

•Particle filters do NOT protect against

gas and vapour.

•Gas filters do NOT protect against

particles.

•Certain gas filters protect ONLY against

certain gases and vapours.

Where should you NOT use the SR900 fitted

with filters?

There are a few situations where your half face

respirator with filters cannot be used. In many of

these situations, filter protection is inadequate,

and you will need an external air supply:

•In oxygen-deficient areas (that is, there

is not enough oxygen in the air for

human breathing)

•Where the atmosphere is Immediately

Dangerous to Life and Health (IDLH)

•Where the concentration of the hazard is

too great to use a half mask or filter

protection according to your local laws

and regulations

Using the SR900 with other breathing devices

For information on other breathing devices such

as PAPRs and supplied-air equipment, please see

separate training modules on those devices.

One mask — one user

Your mask is a personal item. Do not share

masks with others, and always store your own

respirator in a place where it can’t be mixed up

with other masks.

The best way to keep track of your own mask is

to use masks fitted with an ID tag. The tag makes

sure that your mask won’t be mistaken for

someone else’s.

The SR900 is fitted with a slot where you can

fasten a barcode or ID tag.

Before fitting the respirator:

•Make sure your face is clean shaven and

washed.

•Check the mask for any damage.

•Ensure that the mask is clean and dry.

•Check that the filter/cartridge is properly

fitted.

•Make sure that you are using the correct

filter/cartridge.

•Perform a leakage test.

Tell your supervisor IMMEDIATELY if…

•you experience any problems breathing

through your respirator.

•you have troubles wearing the respirator

together with other safety gear (hardhat,

goggles, ear muffs etc.)

•you notice any damage to the mask.

•the leakage test doesn’t work.

•you are unsure of use or maintenance of

the respirator.
