System Description
The 3M™ Versao™ M-Series Headgear is a family of respirators designed to help meet the changing
needs of users through a modular design and convertibility of major components. The M-100, M-200
and M-300 Series loose tting facepieces and the M-400 Series Helmets are designed to be used with
certain 3M™ Breathing Tubes and Powered Air Purifying (PAPR) or Supplied Air (SA) units to form a
respiratory system. In addition, all 3M™ M-Series Headgear meet the test requirements of certain eye
and face protection standards, and the M-300 and M-400 Series Headgear meet test requirements
of certain industrial head protection standards. See “Approvals” section of these User Instructions for
additional information.
The M-100 Series Respiratory Faceshields have a wide-view ip-up visor, fully adjustable ratchet
suspension, and a fabric faceseal. An integral air deector allows the user to position the airow for
wearing comfort. When used with the optional M-170 Faceshield Inserts, the M-100 Series Headgear
offers lightweight head coverage from dirt, debris, and overspray as well as minimal head protection from
contact with stationary objects (i.e. “bump” protection).
The M-200 Series Respiratory Faceshields have similar features to the M-100 Respiratory Faceshields,
including a liftable wide-view visor assembly and an integral air deector to direct the airow inside the
headgear. Unlike the M-100 Series Headgear, the M-200 Series Headgear comes with a solid headgear
shell to provide lightweight head coverage from dirt, debris, and overspray as well as minimal head
protection from contact with stationary objects (i.e. “bump” protection).
The M-300 Series Respiratory Hardhats have similar features to the M-100 and M-200 Respiratory
Faceshields, including a liftable wide-view visor assembly and an integral air deector to direct the
airow inside the headgear. Unlike the M-100 Series Headgear, the M-300 Series Headgear comes
with a solid headgear shell, and unlike the M-100 or M-200 it has been tested to certain industrial head
protection standards.
The M-400 Series Helmets are designed to offer the highest level of respiratory protection of the M-Series
range. This “jawed” product provides coverage for the neck and shoulders through a versatile two piece
inner and outer neck shroud design. The M-400 Series Headgear uses the same fully adjustable head
suspension and headgear shell as the M-300 Series Headgear.
Optional accessories and a variety of faceseal, shroud, and visor materials are available for the M-Series
Headgear, giving the user a choice of congurations for specic applications.
WWARNING
Properly selected, used, and maintained respirators help protect against certain airborne contaminants
by reducing airborne concentrations in the wearer’s breathing zone below the Occupational Exposure
Limit (OEL). It is essential to follow all instructions and government regulations on the use of this
product, which includes wearing the complete respirator system during all times of exposure, in order
for the product to help protect the wearer. Misuse of respirators may result in overexposure to
contaminants and lead to sickness or death. For proper use, see supervisor, refer to the product
User Instructions or contact 3M Technical Service.

supervisor, User Instructions or call 3M in U.S.A., 1-800-243-4630. In Canada, call Technical Service
at 1-800-267-4414.
2. These products meet the requirements of certain industrial eyewear standards and with some
models, certain industrial head protection standards. They do not provide complete head, eye, and
face protection from severe impact and penetration and are not a substitute for good safety practices
and engineering controls. Misuse may result in serious injury or death. For proper use, see
supervisor, refer to the product User Instructions or contact 3M Technical Service.
3. When exposed to eye and face hazards, wear additional eye and/or face protectors appropriate to
the hazard. ANSI Z87.1-2010, incorporated by reference in the OSHA Eye and Face Standard 29 CFR
1910.133, suggests safety spectacles or goggles should be worn in conjunction with loose tting
respirators if the visor can be raised from the normal position during use. Failure to do so may
result in serious injury or death.
4. Failure to follow these instructions may reduce the capability of the M-300 and M-400 Series
Headgear Shell to withstand impact and penetration and may result in serious injury or death:
a. Use only the cleaning processes and agents described in these User Instructions to clean the shell.
b. Do not store in direct sunlight.
c. Do not use beyond the maximum life of the product.
d. Do not use in high heat environments above the recommended maximum temperature.
5. The M-100 Series Headgear, when tted with the M-170 Faceshield Head Inserts, and the M-200
Series Headgear, do not meet the test requirements for hard hat protection under ANSI Z89.1-2009.
When head protection is required by OSHA or other safety regulations, hardhats or helmets, such as
the M-300 and M-400 Series, must be used instead of the M-100 or M-200 Series Headgear. Failure
to do so may result in serious injury or death.
6. Failure to follow these instructions may reduce the capability of the M-Series visors to withstand
impact and penetration and may result in serious injury or death:
a. Use only the cleaning processes and agents described in these User Instructions to clean the visor.
b. Ensure visor buttons are rmly secured and ush to the visor frame. Replace worn or
damaged parts.
7. Failure to follow these instructions may reduce respirator performance, overexpose you to
contaminants, and may result in sickness or death:
a. Always properly assemble and wear both the inner and outer shroud (M-400 Series).
b. Ensure visor frame rmly latches in the closed position. Replace worn or damaged parts
(M-400 Series).
c. Users must be clean-shaven where the respirator’s faceseal comes into contact with their face
(M-100, M-200 and M-300 Series).

8. Use of the Head, Neck, and Shoulder Cover (M-976) does not increase the Assigned Protection
Factor (APF) of the M-100, M-200 and M-300 Series Headgear. The M-976 is designed to help keep
the wearer and headgear clean and does not increase the level of respiratory protection provided.
Improper use may overexpose you to contaminants, and may result in sickness or death.
9. Do not use the Head, Neck, and Shoulder Cover (M-976) or non-ame resistant faceseals and
shrouds around high heat, sparks or ames. Misuse may result in serious injury or death.
10. Do not use the Shaded Peel-Off Cover (M-929) for welding.The Shaded Peel-Off Cover (M-929)
will not protect the wearer’s eyes from the harmful level of visible light, ultra-violet radiation (UV),
and infrared radiation (IR)) resulting from gas and arc welding processes. Misuse may result in
permanent eye injury and vision loss. For welding use an ANSI Z87.1 complaint welding helmet
with an appropriate lter lens for the specic welding process.
11. Only use the Shaded Peel-Off Cover (M-929) on the 3M™ Versao™ M-Series Headgear. Do not use

ACCESSORIES
WWARNING
1. The M-100 Series Headgear, when tted with the M-170 Faceshield Head Inserts, and the M-200
Series Headgear do not meet the test requirements for hard hat protection under ANSI Z89.1-2009.
When head protection is required by OSHA, or other safety regulations, hardhats or helmets, such
as the M-300 and M-400 Series Headgear, must be used instead of the M-100 or M-200 Series
Headgear. Failure to do so may result in serious injury or death.
2. Use of the Head, Neck, and Shoulder Cover (M-976) does not increase the Assigned Protection
Factor (APF) of the M-100, M-200 or M-300 Series Headgear. The M-976 is designed to help keep
the wearer and headgear clean and does not increase the level of respiratory protection provided.
Improper use may overexpose you to contaminants, and may result in sickness or death.
3. Do not use the Head, Neck, and Shoulder Cover or non-ame resistant faceseals and shrouds around
high heat, sparks or ames. Misuse use may result in serious injury or death.
4. Do not use the Shaded Peel-Off Cover (M-929) for welding.The Shaded Peel-off Cover (M-929)
will not protect the wearer’s eyes from the harmful level of visible light, ultra-violet radiation (UV),
and infrared radiation (IR)) resulting from gas and arc welding processes. Misuse may result in
permanent eye injury and vision loss. For welding use an ANSI Z87.1 complaint welding helmet
with an appropriate lter lens for the specic welding process.
5. Only use the Shaded Peel-Off Cover (M-929) on the 3M™ Versao™ M-Series Headgear. Do not use
on any other headgear including faceshields and eyewear. Misuse may result in permanent eye
injury and vision loss.
M-926 and M-928 Peel-off Visor Covers
Ensure the visor is clean and dry before attaching any visor covers. To attach peel-off visor covers, peel
off the paper backing from the adhesive on the edges of the cover. Center the cover over the visor and
press the edges with the adhesive coating against the visor. You may stack up to 5 visor covers on top of
one another. This allows you to quickly peel off covers as they become difcult to see through, reducing
the number of times you must stop working to reapply covers.
NOTE: The M-926 covers are for use with the M-925 uncoated visor and the M-928 covers are for use
with the M-927 coated visor. The M-926 covers have a notch in the tab for easy identication. Use of the
M-928 covers on the uncoated M-925 visor may leave residue upon removal.
M-929 Shaded Peel-Off Cover
The 3M™ Versao™ Shaded Peel-off Visor Cover (M-929) is an optional accessory for the 3M™
Versao™ M-Series Headgear. The peel-off is optimized for the M-927 premium visor. Use of the M-929
cover on the uncoated M-925 visor may leave residue upon removal.
The shaded peel-off cover M-929 complies with the shade W3.0 transmission requirements listed in
Table 6 of the American Standards Institute Eye and Face Protection standard ANSI Z87.1-2010. The
peel-off cover is intended for use in torch brazing and soldering applications. For additional information

5. Verify the peel-off is centered on the visor and there is minimal gap between the visor frame
assembly and the peel-off cover.
6. If the peel-off is not centered on the visor, remove the peel-off and repeat steps 1-5 above with a
new peel-off cover.
7. Read completely and follow the User Instructions for the M-Series Headgear and your 3M™ Supplied
Air Device or powered air purifying respirator to complete system assembly and performance checks.
NOTE: Use only one peel-off cover at a time. Do not stack multiple M-929 shaded peel-off covers on
the M-Series Visor. Do not use any other peel-off cover in combination with the M-929 including the clear
peel-off visor covers M-926 and M-928.
Carefully inspect the peel-off for damage before each use including holes, tearing, ripping, peeling,
discoloration, and hazing. If you discover any signs of damage, remove headgear from use and
replace the peel-off visor cover with a new one. Failure to do so may affect performance and
reduce the degree of protection provided.

that is protected from contamination, damage, dirt, debris, product distortion, and direct sunlight. Do
not store next to furnaces, ovens, or other sources of high heat. When stored in accordance with the
recommended storage conditions listed in these User Instructions,product may be used until “use by”
date specied on packaging.
M-170 Faceshield Head Inserts
The head inserts can be snapped into the M-100 Series Headgear to create a closed shell that provides
minimal head coverage against contact with stationary objects or hard surfaces. The inserts also help to
protect the wearer’s head from overspray, dust, dirt and debris. The inserts can be installed and removed
as required. The inserts are marked with an “X” and an “O” respectively (Fig. 18a). To install, match
the marking on the insert with the corresponding marking on the M-100 shell (i.e. match “X” to “X”) as
