APPROVAL FOR USE
The MPV supplied air-fed vizor respirator is
CE approved under PPE Directive 89/686/
EEC. The visor conforms to European Eye-
Protection standard EN166, category F for low
energy Impact and liquid splash protection.
An MPV supplied air vizor system, correctly
fitted and applied by trained personnel in
accordance with these instructions, may be
used subject to the user determining its
suitability, for protection from particles, fumes,
gases and vapours. The respirator should
only be used with Devilbiss original
components to maintain approval for the
system, this includes the compressed air

DESCRIPTION
The MPV supplied air vizor has a lightweight
fully adjustable headband. The neck and ears
are also protected with a disposable cover.
The vizor has a diffused compressed air feed
tube. The vizor can be lifted up from the face
when the operator is not working in a
hazardous area. Two half turn tension knobs
adjust the vizor movement.
The vizor air feed tube is connected to its
associated filter/regulator which is attached at
the waistbelt. The preset compressed air
pressure regulator maintains a constant flow
of air to the vizor. Manufacturers minimum
design flow rate 140 litres/min (4.9 Ft³/min).
The disposable activated carbon filter
removes odour, oil and vapour.
A short hose with connections is supplied for
the attachment of a spray gun to the
connection provided see fig 1.
Two disposable vizor covers and a
disposable hood for additional skin protection
when used with materials containing
chemicals that have harmful effects, are also
provided, i.e when spraying 2 pack paints.

SUITABILITY FOR USE
It is the duty of the employer to determine such
suitability and in so doing the following factors
should be considered bearing in mind that the
circumstances of use determine the level of
protection provided.
1) The respirator must not be used in
atmospheres immediately dangerous to life or
health; i.e those atmospheres from which it
would not be possible to escape without risk to
life or health. Such atmospheres include those
deficient in oxygen.
2) The respirator must not be used in
atmosphere where the concentration of
contaminant may exceed the allowable
exposure limit and it should be noted that at
exceptionally high levels of physical work the
peak inhalation may exceed the constant flow
of supplied air. (See Specification)
3) The wearer must be able to adjust and fit
the respirator correctly. The wearer must be
trained in the correct wearing and operation of
the respirator and understand the limitations of
use.
4) The employer should ensure that the
respirator, which is intended for light duty
service, is suitable and that the appropriate
model is selected and that the trailing supply
hose will not present a hazard to the wearer or
others in the vicinity. Refer to - HSG 53. The
selection use and maintenance of respiratory
protective equipment (HSE Guide).
5) The employer must provide a suitable
management system, to ensure that the
respirator is maintained in accordance with the
manufacturers instructions. Refer to - BS4275:
1997 Guide to implementing an effective
respiratory protective device programme.

WARNING: NEVER USE THIS RESPIRATOR
IN AN AREA WHERE THE ATMOSPHERE IS
IMMEDIATELY HAZARDOUS TO LIFE
OR HEALTH. IN AN EMERGENCY THE
WEARER MUST BE ABLE TO ESCAPE FROM
THE WORK AREA WITHOUT THE NEED OF A
RESPIRATOR.
THE AIR SUPPLIED MUST BE OF
BREATHABLE QUALITY AND CONFORM TO
BSEN 12021:1999 AND THE RELEVANT
NATIONAL AND LOCAL STANDARDS.
ONLY USE RECOMMENDED DEVILBISS
SUPPLY HOSE
CAUTION: It is essential to site the air intake of
the compressor so that the air intake is free
from contaminants. The compressed air must
be regularly checked for breathable quality.
As a precaution against a supply failure or
pressure loss an audible low pressure warning
device should be fitted as described under
accessories.
NOTE: It is recommended that a new air
supply hose item (18) fig1 is used and specially
identified for breathing air. In the interest of
hygiene each user should have their own face
mask and hood.
HOSE LENGTH: Note 10m is the maximum
hose length that can be used due to the
minimum pressure requirements.
If longer hose length is required a portable
coalescing air filter device must be located at
the supply end of the10m hose and be capable
of supply pressure of 3.8 Bar (55 lbf/in²) at this
point.
INSTALLATION / OPERATION
DONNING PRODEDURE
WARNING: DO NOT ENTER THE
CONTAMINATED AREA UNTIL ITEM (10) IS
COMPLETED
1) Connect the air supply hose to the outlet of a
coalescing air filter such as a DVFR 2. Do not
turn on the air supply.
NOTE: Ensure that the supply hose is of
sufficient length to allow the operator to enter
and leave the contaminated area without
disconnecting or removing the vizor.
2) Check the waistbelt and respirator
assemblies ensuring that all parts are in good
condition. Replace if damaged.
3) Attach and adjust the waistbelt assembly
ensuring that the supply air inlet and spray gun
outlet connectors are pointing down.
4) Connect the air supply hose to the waistbelt
inlet.
5) Connect the respirator feed tube to the outlet
socket on top of the filter assembly.
6) Connect the spray gun air supply hose to QD
outlet on the bottom of the filter assembly (if
required).
7) Place the vizor assembly on the head and,
with the vizor in the open position, adjust the
tension knobs.
Ensure that the feed tube is not twisted or
kinked and will not interfere with normal
movements.
8) Turn on the air supply and check that the air
is flowing freely to the inside of the vizor.
9) Adjust the air pressure with the gun (if fitted)
triggered to ensure that the minimum supply
pressure at the inlet of supply hose is in
accordance with the minimum requirements 3.8
bar (55 psi).
10) Before entering the contaminated area, the
vizor must be pulled down, so that the material
face seal is located under the chin and in
contact around its entire periphery, the tension
knobs are adjusted so that the vizor is locked in
this position.
NOTE: Do not lift or remove the vizor inside the
contaminated area. Retreat from the area
immediately if any malfunction is suspected or if
the warning whistle sounds (if accessory fitted).
