Filters /Cartridges - Sundstrom SR 500 Mode D'emploi

There are two breathing hose types available for the SR
900 facepiece - single hose and twin hose. The
breathing hose for the SR 900 half mask mask is sold
separately. To assemble the breathing hose to the SR
900, see User's instruction for the hoses SR 591 and
SR 592.
There are two breathing hose types available for the SR
200 facepiece – PU and rubber. The breathing hose for
the SR 200 full facepiece mask is sold separately.
The breathing hose is supplied with the relevant
respiratory inlet covering. To assemble the breathing
hose to the SR 200 proceed as follows:
• One end of the hose is provided with a threaded
adapter. Connect the adapter to the filter thread of
the mask. Fig. 8.
• Check that the O-ring of the hose is in place. Fig. 6.
• Connect the hose to the fan unit and turn it
clockwise about 1/8 of a turn. Fig. 7.
Check that the hose is firmly secured.

4.6 Filters /Cartridges

The choice of filters (SR 510, SR 710)/combined filter /
cartridge (SR 510/SR 532, SR 510/SR 533) depends on
factors such as the type and concentration of
pollutants. The fan unit may be used with only
particulate filters or with a combination of particulate
filters and chemical cartridges.
WARNING: Read carefully the user instructions
accompanying the filters and cartridges.
WARNING: No signal is activated when the gas
cartridges are saturated. Consult your supervisor
or respiratory protection program administrator for
the change schedule applicable to your work site.
WARNING: DO NOT use the canister if the bag is
opened, damaged, or missing. The canister must
be in its original packaging prior to use in a
contaminated environment. Do not reuse the
canister.
Pre-filter holder
Fit in the pre-filter holder, which protects the main filters
against handling damage. Fig.
P-100 /HE Particulate Filters
Sundström markets only particle filters of the highest
class P100 /HE. Two models are available for use with
the SR 500 fan unit, 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 chemical cartridge. The SR 710
cannot be combined with a chemical cartridge. The
SR 710 can be used with the same pre-filter holder (SR
5153), as the one used with any Sundström air-purifying
respirator face masks (e.g. ½ mask SR 100, full face
mask SR 200).
Chemical cartridges
The chemical cartridges must always be combined
with a P100 /HE particle filter (SR 510). Press the filter
and cartridge together so that the arrows on the
PARTICULATE filter point towards the chemical
cartridge. Fig. 14.

The SR 532 chemical cartridge protects against
organic gases and vapors, e.g. solvents, with a boiling
point of more than +65 °C. It protects against acidic
gases and vapors, such as sulphur dioxide, chlorine,
hydrogen chloride and hydrogen fluoride.
The SR 533 gas cartridge protects against acidic gases
and vapors, such as chlorine, hydrogen chloride,
sulphur dioxide and formaldehyde. It protects against
ammonia and certain amines.
The following filters are available for the SR 500:
• SR 510 particulate filter P100 /HE is used with an
adapter to permit threading into the fan unit. Two
filters are required to operate with the fan unit. This
filter can be combined with a chemical cartridge by
snapping it onto a chemical cartridge.
• SR 710 particulate filter P100 /HE contains threads
and is threaded directly into the fan unit. An adapter
is not needed. Two filters are required to operate
with the fan unit. This filter cannot be combined with
a chemical cartridge.
• SR 532 chemical cartridge provides protection for
organic vapors and acid gases. For particulate
protection it can be combined with an SR 510
particulate filter. Two cartridges or combination
filter/cartridges are required to operate with the fan
unit.
• SR 533 chemical cartridge provides protection for
acid gases, ammonia and certain amines. For
particulate protection it can be combined with an SR
510 particulate filter. Two cartridges or combination
filter/cartridges are required to operate with the fan
unit.
Two filters or combined filter/cartridge of the same type
and class must always be used at the same time. To
install the filters or combination filter/cartridges proceed
as follows:
Particulate filter SR 510
• Check that the gaskets in the filter mounting of the
fan unit are in place and are in good condition.
Fig. 9.
• Snap the particulate filter onto the filter adapter. Do
not press onto the centre of the filter - it might
damage the filter paper. Fig. 10.
• Screw the adapter into the filter mounting so far that
the adapter will be in contact with the gasket. Then
turn it about 1/8 turn further in order to ensure a
good seal. Fig. 11.
Particulate filter SR 710
• Check that the gaskets in the filter mounting of the
fan unit are in place and are in good condition.
Fig. 9.
• Screw the filter into the filter mounting so far that the
adapter will be in contact with the gasket. Then turn
it about 1/8 of a turn further in order to ensure a
good seal. Fig. 11.
Combined filter/cartridge
• Check that the gaskets in the filter mounting of the
fan unit are in place and are in good condition.
Fig. 9.
• Snap the particulate filter onto the chemical
cartridge. The arrows on the particulate filter must
point towards the chemical cartridge. Do not press
onto the centre of the filter - it might damage the
filter paper. Fig. 14.
