USER MANUAL
Important
Please read and remember the following
instructions before use to ensure your own
safety. If you have any questions, please contact
the manufacturer or your distributor. Keep the
manual for future reference. The welding helmet
should be used only for the purposes listed in
this manual.
1. Introduction
When used in accordance with these instructions,
CleanAIR® Omnira / Omnira air is designed to
protect the user´s eyes and face against high
speed particles. It is a multipurpose protective
faceshield that can be easily converted to
professional welding helmet with flip-up welding
shield CleanAIR® Omnira COMBI /Omnira COMBI
air.
CleanAIR® Omnira COMBI / Omnira COMBI air is
designed to protect the user´s eyes and face
from harmful radiation including visible light,
ultra-violet (UV), infra-red (IR) radiation and hot
sparks and spatters resulting from arc welding
and cutting applications such as MIG, MAG, TIG,
SMAW, Plasma Arc, Carbon Arc gouging. This
welding helmet is not recommended for heavy
duty overhead welding applications, laser welding
or Iaser cutting applications.
CleanAIR® Omnira air / Omnira COMBI air is adapted
for use with powered air purifying respirators
(hereinafter PAPR) CleanAIR® or with continuous
flow compressed air breathing apparatuses
(hereinafter „compressed air system") CleanAIR®
and thus provides protection of the respiratory
tract.
CleanAIR® is a system of personal respiratory
protection based on the principle of overpressure
of filtered air in the breathing zone. The respirator
is placed on the wearer's belt and filtrates the air
which is taken in from the surrounding environment
and then delivers it through the airduct into the
protective helmet. The overpressure prevents
contaminants from entering the breathing zone.
This mild overpressure at the same time ensures
the wearer's comfort, even with long-term use,
as the wearer does not have to struggle in their
breathing to overcome the resistance of the filter.
2. Before you start working

CleanAIR® Omnira COMBI / Omnira COMBI air
Ensure that the helmet is correctly assembled
and that it completely blocks any accidental light.
In the front, light may enter the helmet only throu-
gh the viewing area of the welding filter. Ensure
that the welding shield is parked in the lower po-
sition before you start welding. Adjust the head-
gear to ensure maximum comfort and to provide
the largest field of vision. Check the prescribed
shade level for your welding application and adj-
ust your auto-darkening filter accordingly (select
appropriate passive welding filter) - see the table
with recommended shade levels). Inspect that
the main protective visor is undamaged, clean
and installed correctly. Replace the visor imme-
diately, if it is damaged, or if spatter or scratches
reduce vision. Inspect that the protection plates
are undamaged, clean and installed correctly.
Replace the plate immediately, if it is damaged,
or if spatter or scratches reduce vision. Inspect
that the welding filter is undamaged and clean.
The damaged welding filter impairs protection
and visibility and must be replaced immediately.
Inspect that the welding helmet and headgear are
undamaged.

Ensure that the protective faceshield is correctly
assembled. Adjust the headgear to ensure
maximum comfort and to provide the largest
field of vision. Inspect that the protective visor
is undamaged, clean and installed correctly.
Replace the visor immediatelly, if it is damaged,
or if spatter or scratches reduce vision.
WARNING – CleanAIR® Omnira COMBI / Omnira
COMBI air, CleanAIR® Omnira / Omnira air
• Do not use CleanAIR® Omnira COMBI / Omnira
COMBI air for welding if the welding shield is
in the upper position! The clear visor doesn´t
protect against harmful radiation.
• Use only original CleanAIR® / AerTEC™ spare
parts and consumables. In case of doubt,
please contact your authorized distributor.
The use of substitute components or any
modifications not specified in this manual
might impair protection and may invalidate
claims under the warranty or cause the
product to be non-compliant with protection
classifications and relevant standards and
certificates.
• Never place the helmet or the auto-darkening
welding filter on hot surface.
• Scratched or damaged protection visors or
plates should be regularly replaced by original
CleanAIR® ones. Before using a new visor or
protection plate, make sure to remove any
additional protection foil from both sides.
• Do not use tempered mineral filters without
suitable protection foils.
• Replace protection plate immediately, if it is
damaged, or if spatter or scratches reduce
vision.
• Do not expose the auto-darkening welding filter
to liquids and protect it from dirt.
• Materials which may come into contact
with the wearer's skin could cause allergic
reactions to susceptible individuals.
• Welding helmet worn over standard ophthalmic
spectacles may transmit impact, thus create
a hazard to the wearer.
Limitations on use of CleanAIR® Omnira COMBI
air / Omnira air
Never use the helmet in the following envi-
ronments and under the following conditions:
• If oxygen concentration in the environment is
lower than 17 %.
• In oxygen-enriched environments.
• In explosive ambience.
• In environments that represent an immediate
threat to the life and health.
The helmet does not protect against hard shocks,
explosions or corrosive substances.
Do not use in environments where the user
does not know the type of contamination or its
concentration.
Do not use when the powered air purifying
respirator is turned off or when the compressed
air inlet is closed! In this case the respiratory
system gives little or no respiratory protection.
Also there is a risk of a high concentration of
carbon dioxide (CO2) building up and a risk of
oxygen deficiency occurring inside the helmet.
Move to a secure location and take appropriate
measures when any of the following problems
occur while using the helmet:
• If the PAPR or the compressed air system
cease to operate for any reason whatsoever,
the user must leave the contaminated
workplace without delay.
• If you experience stench or irritation or an
unpleasant taste while breathing.
• If you feel unwell or if you experience nausea.
Filters designed for capturing solid and liquid
particles (particle filters) do not protect the user
against any gases. Filters designed for capturing
gases do not protect the user against any partic-
les. In the workplace contaminated by both types
of pollution, combined filters must be used.
3. Control and spare parts replacement
Replacing the visor (*PICTURE ANNEX 1)
Shift the visor locks on both sides up (unlock)
and remove the visor. Place the new visor on the
same spot and shift both locks on the sides back
down (lock). Make sure the visor fits properly.
Replacing the flip-up welding shield (*PICTURE
ANNEX 2)
You can remove the welding shield by pressing
the locking buttons on both sides of the helmet
while pulling the welding shield out. Install the
new flip-up welding shield by clicking the pivot
mechanisms into mounting points of the face
shield.
How to upgrade your grinding face shield
Omnira into flip-up welding helmet Omnira
COMBI (PICTURE ANNEX 3)
The mounting points of the flip-up welding shield
are covered by round plastic covers on both sides
of the face shield. You can easily remove them by
pulling out. Install a new flip-up welding shield by
clicking the pivot mechanisms into mounting po-
ints of the face shield.
Face seal replacement (*PICTURE ANNEX 4)
Remove the headgear as described in section
„Headgear replacement".
Loosen both tension knobs on both sides and
