GENERAL SAFETY INFORMATION
Intended Use
The 3M™ V-Series Air Control Devices are designed to be used with certain 3M headgear, breathing tube
and supplied air hose to form a complete NIOSH approved respiratory system. When used in accordance
with its NIOSH approval, these systems can provide positive pressure, supplied air respiratory protection.
3M headgear (respiratory inlet covering) may include a tight fitting facepiece, loose fitting facepiece, hood,
helmet or some combination of these that serves as a respiratory protective covering for the nose and mouth
area. Refer to the enclosed 3M™ V-Series Air Control Device NIOSH approval label for approved system
configurations.
List of Warnings and Cautions within these User Instructions
This product helps protect against certain airborne contaminants. Misuse may result in sickness or
death. For proper use, see supervisor.
The length of compressed air hose W-3020 used depends on the specifications of the low-pressure air pump
utilized. Some pumps specify a minimum of 50 or 100 feet of hose to allow adequate cooling of the air
heated by the pump's mechanism. Read the pump’s instructions thoroughly before selecting the compressed
air hose W-3020 length that will be used. NO PUMP IS TO BE USED WHICH COULD CAUSE AIR
HOTTER THAN 160º F (71º C) TO ENTER THE COMPRESSED AIR HOSE W-3020. Air hotter than 160º
F (71º C) will cause the hose to degrade, which would adversely affect respirator performance and may
result in sickness or death.
To meet the NIOSH requirement in 42 CFR 84, subpart 84.150 for minimum and maximum airflow (6 to 15
scfm, 170 to 425 lpm), the air control devices approved for use with 3M headgear must be operated within the
supply pressure ranges and hose lengths stated in the Special or Critical Use Instructions. Failure to do so
may adversely affect respirator performance and result in sickness or death.
You must comply with OSHA Standard 29 CFR 1910.134, which states that, “Airline couplings shall be
incompatible with outlets for other gas systems to prevent inadvertent servicing of airline respirators with
nonrespirable gases or oxygen.” In Canada, refer to the requirements of CSA Standard Z180.1 or the
authority having jurisdiction in your region. Failure to do so may result in sickness or death.
Your employer must provide breathing air that meets at least the requirements of the specification for Grade
D breathing air, as described in the Compressed Gas Association Commodity Specification G-7.1-1997 in the
United States. In Canada, refer to CSA Standard Z180.1, table for the quality of compressed breathing air.
Failure to do so may result in sickness or death.
The line pressure must be kept within safe limits, 125 psig (8.75 kg/cm2) maximum. Dirt, oil and water,
unless trapped or filtered out, may continue downstream in concentrated form and adversely affect the
performance of the respirator and result in sickness or death.
Use of equipment described in these User Instructions must be in accordance with applicable health and
safety standards, respirator selection tables contained in such publications as ANSI Z88.2-1992, CSA
Standard Z94.4, or pursuant to the recommendations of an industrial hygienist. Before occupational use of
these respirators, a written respiratory protection program must be implemented meeting all the requirements
of OSHA 29 CFR 1910.134 such as training, fit testing, medical evaluation, and applicable OSHA substance

or death. Do not wear this respirator where:
–
Atmospheres are oxygen deficient
–
Contaminant concentrations are unknown
–
Contaminant concentrations are Immediately Dangerous to Life or Heath (IDLH)
–
Contaminant concentrations exceed the maximum use concentration (MUC) determined using the
assigned protection factor (APF) recommended for the applicable headgear or the APF mandated by
specific government standards, whichever is lower. Refer to the User Instructions provided with the
applicable headgear.
Contaminants that are dangerous to your health include those that you may not be able to see or smell. Leave
the contaminated area immediately if any of the following conditions occur. Failure to do so may result in
sickness or death.
– Any part of the system becomes damaged
–
Airflow into the respirator decreases or stops
–
Breathing becomes difficult
–
You feel dizzy or your vision is impaired

Compressor Volume
Requirements –
Approximately 20 CFM per 3M™ Air Control Device
Noise Level –
Less than 80 dBA within the headgear; excluding external noise
The length of compressed air hose W-3020 used depends on the specifications of the low-pressure air pump
utilized. Some pumps specify a minimum of 50 or 100 feet of hose to allow adequate cooling of the air
heated by the pump's mechanism. Read the pump’s instructions thoroughly before selecting the compressed
air hose W-3020 length that will be used. NO PUMP IS TO BE USED WHICH COULD CAUSE AIR
HOTTER THAN 160º F (71º C) TO ENTER THE COMPRESSED AIR HOSE W-3020. Air hotter than 160º
F (71º C) will cause the hose to degrade, which would adversely affect respirator performance and may
result in sickness or death.
Discussion on Respirable Air
Many older compressed air systems may provide air that is unfit for human respiration without secondary air
treatment. This is due largely to the presence of objectionable oil vapors and odors. Rules and regulations
governing air quality when using compressed air for respiration are quite specific.
Precautions must be observed when using compressed air for breathing purposes.
Oil mist from the compressor lubricating oil must not be present when the air reaches the air control device.
Excessive amounts of water vapor and any particulate matter should also be removed as they may affect
performance of the air control devices. The schematic diagram of the air purifier and pressure regulator
equipment shows what should be installed in the main airline ahead of the connection for the breathing air
hoses (Fig. 1).

netzerotools.com
netzerotools.com
Fig. 1: Air purification and regulation equipment.
If a pre-assembled air filtering and regulating device is desired, 3M offers several compressed air filter and
regulator panel assemblies. These assemblies contain a specially designed filter cartridge to help remove oil
mist and vapors, condensed moisture, particulates, odors and vapors. They come completely assembled and
are ready for connection between the compressor and supplied air respirator system. These air filtering and
regulating devices do not ensure Grade D breathing air as required.
Note: Carbon monoxide- Although it is theoretically possible that oil lubricated compressors can create
carbon monoxide (CO) if the compressor overheats, studies have shown that the location of the compressor’s
air intake is the most likely source of carbon monoxide contamination.1 According to OSHA regulation [29
CFR (1910.134)(i)], periodic CO monitoring, rather than continuous CO monitoring with an alarm, is
acceptable if the oil lubricated compressor is equipped with a high temperature alarm and automatic shutdown. In Canada, follow CSA Z180.1 regarding oil lubricated compressors.

Formation of carbon monoxide in air compressors, Am. Ind. Hyg. Assoc. J (40), June 1979, pp. 548-551
To meet the NIOSH requirement 42 CFR 84, subpart 84.150 for minimum and maximum airflow (6 to 15
cfm, 170 to 425 lpm), the air control devices approved for use with 3M headgear must be operated within the
supply pressure ranges and hose lengths stated in the Special or Critical Use Instructions. Failure to do so
may adversely affect respirator performance and result in sickness or death.
You must comply with OSHA standard 29 CFR 1910.134, which states that, “Airline couplings shall be
incompatible with outlets for other gas systems to prevent inadvertent servicing of airline respirators with
nonrespirable gases or oxygen.” In Canada, refer to the requirements of CSA Standard Z180.1 or the
authority having jurisdiction in your region. Failure to do so may result in sickness or death.
Your employer must provide breathing air that meets at least the requirements of the specification for Grade
D breathing air, as described in the Compressed Gas Association Commodity Specification G-7.1in the
United States. In Canada, refer to CSA standard Z180.1, table for the quality of compressed breathing air.
Failure to do so may result in sickness or death.
The line pressure must be kept within safe limits, 125 psig (8.75 kg/cm2) maximum. Dirt, oil and water,
unless trapped or filtered out, may continue downstream in concentrated form and adversely affect the
performance of the respirator and may result in sickness or death.

–
You suspect that the concentration of contaminants may have reached levels at which this respirator may
no longer provide adequate protection.
Never alter or modify this assembly.
Air supply piping, fittings, and compressors must have the capacity to deliver sufficient air volume (6 to 15
cfm, 170 to 425 lpm) to operate the air control device at the recommended pressure.
If you have any doubts about the applicability of the equipment to your job situation, consult your supervisor
or an industrial hygienist.
V-100, V-200, and V-300
To use these 3M air control devices with approved 3M headgear, breathing tube and supplied air hose
proceed as follows:
1.
Connect one end of the breathing tube to the selected headgear. (Follow the directions in the specific
headgear User Instructions.)
Note: If the H-115 Breathing Tube Assembly is used, the tube length may be trimmed to suit the user.
Trim only the end that will be connected to the headgear. The tube must not be adjusted to a length less
than 12 inches (30.5 cm).
2.
Connect the breathing tube to the air control device. Connect the threaded end of the breathing tube to
the threaded outlet on the air control device by screwing the two units together.
Note: If using a BT series breathing tube, first
screw the 3M V-199 adapter into the outlet
port of the air control device. Position the
breathing tube so that the two locking studs
are aligned with the openings of the two Lshaped slots on the adapter outlet. Press in
straight and twist so that the locking studs are
engaged at the end of the L-shaped slots (Fig.
6).

CLEANING, INSPECTION AND STORAGE
These air control devices have no moving parts except the control knob, so there is little to wear out. If
proper filtration of compressed air is maintained, the muffler will stay clean and maintain its acoustic
efficiency.
Additional maintenance and care of respirators should be followed per ANSI Standard Z88.2-1992, Practices
for Respiratory Protection. In Canada, follow CSA Standard Z94.4 or the requirements of the authority
having jurisdiction in your region.
Cleaning
Waist Belt (W-2963) and Decontaminable Waist Belts (W-3217, 520-02-23, and GVP-117)
The waist belt may be hand laundered with a mild detergent, a clean rinse and air-drying.
V-100
DUE TO THE NEED FOR INSTRUMENTATION TO CALIBRATE FOR PROPER AIRFLOW, THE
VORTEX AIR COOLER IS TO BE DISASSEMBLED ONLY TO THE EXTENT SHOWN IN FIG. 2. DO
NOT LOOSEN OR REMOVE THE SET SCREWS IN THE CONTROL KNOB (ITEM 13) BECAUSE OF
CRITICAL POSITIONING OF THE VALVE AND THE NEED TO USE INSTRUMENTATION FOR
PROPER ADJUSTMENT OF THE AIRFLOW. RETURN TO THE FACTORY FOR REPAIR IF THE
CONTROL KNOB COMES OFF.
To clean the tube assembly, simply flush with soap and water followed with a water rinse. Do not insert a
brush in the tube.
It is important to keep the slots of the generator (item 6) clean.
17

Over tightening of the turbine cap (item 3) on re-assembly can cause the generator slots to restrict, thereby
reducing airflow.
To replace the acoustic foam pad (item 11) proceed as follows:
–
Remove the machine screw (item 7) and slide off the body tube (item 12) from the vortex air cooler
with a slight twisting motion.
–
Remove the acoustic foam pad (item 11).
–
Position one end of new acoustic foam pad halfway between the exhaust holes and wrap it around the
3MTM ScotchmateTM strips. Make sure that the ends of the acoustic foam pad do not overlap, but
rather form a snug butt fit.
–
Holding the acoustic foam pad in place with two fingers of one hand, use the other hand to carefully
slide the body tube over acoustic foam and the tube assembly with a slight twisting motion. Apply a
small amount of medium strength thread locker to the machine screw. Secure the body tube with the
machine screw.
