Application
The protective suit is not a breathing apparatus by
itself. It must be worn with a compressed air breath-
ing apparatus. With the apparatus the suit protects
the wearer against toxic agents and materials
harmful to the skin as well as oxygen deficiency.
With the compressed air breathing apparatus the
wearer can move around freely.
Wearing a protective suit and compressed air
breathing apparatus will put a physical strain on the
wearer - he must, therefore, be in good physical
condition. During application proper safety meas-
ures must be taken and observed.

Design of the Protective Suit
3.1
Design
The one-piece suit is made of a compound material
and has a replaceable lens, tightly attached and
replaceable gloves and boots, a gas-tight zipper and
three suit valves.
Under the lens of the chemical protective suit
VAUTEX SL-S there is a distance spacer which
improves the user's freedom of movement.
The back section is enlarged to accommodate a
compressed air breathing apparatus. On the inside
is a reinforcement which can be unbuttoned.
The spacious head part allows wearing a protective
helmet inside the suit. To fit various helmet sizes an
adjustable strap is fixed between the suit valves.
The zipper is on the front, from the right leg to the
head.
3.2
Operation
Breathable air is supplied from the compressed air
breathing apparatus that is worn on the back. The
exhalation air passes through the exhalation valve of
the facepiece into the inside of the suit and then
through the suit valves into the ambient atmosphere.
