Function - MSA S-Cap-Air Manual De Funcionamiento

DESCRIPTION
The air cylinder is strapped into the carry bag and the air pressure indicator can
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 (
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.

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.
