The S-Cap-Air consists of a hood which is connected to a compressed air
cylinder via a medium pressure line. It is stored ready for operation in its carry
bag and is started automatically when the bag is opened.
Compressed air cylinder and bag
The unit is supplied either with a full or an empty compressed air cylinder, as
requested by the customer, and it may be necessary for the customer to fill the
cylinder before first deployment (see enclosed leaflet 10019536). The group of
components, with compressed air cylinder and valve / pressure reducer complies
with European Directive 97/23/ EC.

be read through the window in the bag. Air supply time and donning pictograms
are shown on the bag.
Pressure reducer / cylinder valve
The valve is securely screwed into the compressed air cylinder. The valve cap
with the incorporated start-up pin is located on the valve. Pulling the yellow
unzipping loop pulls the start-up pin out of the valve cap, the valve opens and the
air supply is activated (àSection 3.3).
A continuous stream of air provides the user with air for breathing and prevents
any increase in carbon dioxide in the hood. The air pressure indicator on the
valve provides a continuous read out of the level of air in the cylinder.
Hood
The signal yellow hood is fitted with a large field of view lens, a half mask with
external exhalation valve and a warning indicator which is located directly in the
field of vision.
The warning indicator continuously indicates correct air flow (display: green) and
warns the user to remove the hood by colour change (display: red) at the end of
safe use time.
The internal straps in the hood automatically adjust to locate the half mask over
nose, mouth and chin. The securely located half mask and constant air supply
prevent any increase in carbon dioxide in the hood.
The flexible neck seal does not require adjustment with a properly donned hood.
The hood provides protection for users wearing glasses and also with facial hair.
2.2. Function
The S-Cap-Air provides the wearer with breathable air in the event of an
emergency, for a maximum period of 15 minutes, allowing escape from
dangerous areas. The unit provides a constant stream of breathable air in to the
hood.
The supply of air is started as soon as the unzipping loop is pulled upwards.
When this happens, the seal is broken and the start-up pin is automatically pulled
out of the valve cap on the cylinder opening the valve and bag. Air flows through
the valve and into the hood via the flexible breathing tube and warning indicator.
The hood can then be taken out and donned with a few hand movements.
During use, the hood continuously fills with breathable air which forms an air
reservoir. Air is breathed in from this reservoir via the half mask and is
subsequently breathed out through the exhalation valve into the ambient
atmosphere.

Suitability for adults and device weight
The S-Cap-Air is suitable for adults in good physical and psychological condition.
If the S-Cap-Air weigh more than 5 kg (i.e. when using a 3L 200 bar steel
cylinder), then the unit should not be carried continuously through the working
shift to comply with EN 1146.
Suitability of compressed air cylinders and breathing air
Compressed air cylinders used must comply with national regulations and must
be approved for the relevant pressure.
Only use breathable air which complies with the requirements of EN 12021 or
USCGA grade D (or better).
Regular checking intervals
The unit should be checked at the prescribed intervals. Special care should be
taken to ensure that the cylinder is always filled with breathable air (àSection 6).

3.3. Donning the Respiratory Protection Device
The unit can be donned using a few simple hand movements in about 20 seconds
as follows:
Hanging the S-Cap-Air around the neck
(1) Hang the carry bag around the neck by the
black neck strap.
The inspection window of the bag should point
outwards and the thumb loop should point
down and to the right.
Opening the bag / starting the unit
(2) Insert the thumb of the right hand in the yellow
thumb loop of the carry bag and hold the bag
securely.
(3) Hold the yellow unzipping loop in the left hand
and pull firmly upwards. This pulls out the
start-up pin from the valve of the compressed
air cylinder valve, opening it. The air flow is
audible.
Attention!
This action starts the air supply which lasts
for 15 minutes.
(4) Check that the start-up pin is clear of the valve
cap, if not; fully unscrew the valve cap from the
valve.
Donning the hood with the half-mask
(5) Insert both hands in the ‘prayer’ position into
the hole in the neck seal and then move them
apart spreading the neck seal.
(6) Slide hands and hood down over the head.
(7) Adjust the half mask position on the chin and
nose and press securely to locate.
(8) Check the neck seal for secure sealing.

MSA USE

Checking the indicator in the hood
(9) Check the warning indicator in the hood's field
of vision:
GREEN: Air supply in the hood is correct.
RED: End of use.
Attention!
The indicator changes to RED when the air
supply from the cylinder is coming to an end.
The CO2 concentration in the hood then
increases and the hood must be removed.
Adjustment of the body belt
(10) Close and tighten the body belt.
Starting the escape
(11) Escape calmly and smoothly. Do not take off
the hood until the danger area has been
vacated.
After use the unit must be cleaned, disinfected and checked for damage
(àSection 6); the cylinder should be refilled (àSection 4).
Afterwards put the unit into the carry bag (àSection 5), seal the carry
bag with leads and check the bag (àSection 6).
If a unit has been made ready but not used, it must at least be checked
visually for damage.

FILLING THE COMPRESSED AIR CYLINDER
MSA
10 S-Cap-Air
4. Filling the Compressed Air Cylinder
Attention!
Only breathing air in accordance with EN 12021 or USCGA grade D
(or better) may be used.
Compressors and filling devices may only be operated by trained
personnel. All warning and safety instructions must be observed.
The filling of the compressed air cylinder should be undertaken as follows:
(1) Open the S-Cap-Air bag and remove the seal or its remains.
(2) Carefully remove the cylinder together with the hood connected by the
breathing tube.
If the S-Cap-Air has been used, the start-up pin will no longer be in the
cylinder valve and the valve will be open. In this case the pin will be located
on the unzipping loop of the bag. It has to be reinserted into the valve cap to
close the valve before the cylinder can be refilled.
If the S-Cap-Air has not been used, the start-up pin will still be in the cylinder
valve, with the unzipping loop connected and the valve will be closed. The
pin should be aligned parallel to the breathing tube connection. When filling,
check that the start-up pin securely seals the valve off. If necessary, screw
the cap down a little to tighten it.
(3) Remove the red protection cap from the filling connection.
(4) Connect the filling connection to a 200 bar filling connection and fill to
200 bar at 15ºC. Follow the compressor instructions and use the relevant
adaptor if required.
After filling, open the valve for a short period by unscrewing the cap and then
close it again until the flow of air stops.
