UNPACKING & BATTERY CHARGER SETUP
Unpacking
Inspect the package contents for shipping damage and ensure all components are present. Package contents will vary
depending on components or kit ordered. The product should be inspected before each use following the procedures in the
Inspection section of these User Instructions.
Battery Charger Setup
There are two battery charging options for 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 batteries. The 3M™
Battery TR-641N kit includes (1) 3M™ Charger Cradle TR-640 and (1) 3M™ Power Supply TR-941N. The 3M™ 4-Station
Battery Charger Kit TR-644N includes (1) 3M™ 4-Station Battery Charger Base/Power Supply TR-944N, and (4) 3M™
Charger Cradles TR-640. Refer to the 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 Chargers and Battery Packs
User Instructions for additional information on proper battery pack use and maintenance.
This product is part of a system that helps protect against certain airborne contaminants. Misuse may result in sickness
or death. For proper use, see supervisor, User Instructions or contact 3M Technical Service at 1-800-243-4630 in the
U.S.A.and at 1-800-267-4414 in Canada.
The TR-600 PAPR Assembly is not intrinsically safe. Do not use in flammable or explosive atmospheres. Doing so may
result in serious injury or death.
Refer to the 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 Chargers and Battery Packs User Instructions for
detailed information on charger setup.
• 3M™ Single Station Battery Charger TR-641N: Insert the TR-941N's DC supply cord into the cradle (Fig. 1). Plug the
power cord into an AC power source (100-240V).
• 3M™ 4-Station Battery Charger TR-644N: Insert the TR-640 into one of the charging ports on the 3M™ 4-Station Battery
Station Base TR-944N and slide back to lock into place (Fig. 2). (NOTE: the 3M™ Versaflo™ Single Station Power Supply
TR-941N is not used with the TR-640, when the 4-station charger is used.)
Insert the DC supply cord from the power supply provided with the kit into the 4-station base. Plug the power cord into an
AC power source (100-240V), such as a wall outlet. You may charge any combination of up to four 3M™ Versaflo™ Battery
Packs simultaneously.
• Removal: Release battery pack from cradle – press blue release tab on battery and lift out (Fig. 3, #1).
• The TR-640 can remain attached to the TR-944N if desired. To release the cradle from base, press down on the oval release
tab on the base, slide cradle forward and lift out (Fig. 3, #2). Be careful not to pinch fingers as the cradle slides forward.
NOTE: The TR-640 and TR-944N do not use the same power supply. Use only the power supply provided with your
charger kit.

COMPONENT DESCRIPTION & ASSEMBLY
The 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 System has multiple component options and optional
accessories. At a minimum, each NIOSH approved configuration of this PAPR system should include approved headgear
or facepiece, breathing tube, motor/blower, filter/cartridge, battery, and a belt or backpack. Common accessories include
prefilter/spark arrestor and filter cover. Refer to the supplied User Instructions for each of these components for additional
information prior to use.
High Efficiency (HE) Particulate Filter, Chemical Cartridge/Filter, Prefilter, Spark Arrestor
and Filter Covers
Always correctly use and maintain the filter/cartridge assembly. Failure to do so may reduce respirator performance,
overexpose you to contaminants, and may result in sickness or death.
a. Inspect filter/cartridge and inner circular sealing gasket before each installation. Replace filter/cartridge if damaged or if
the circular gasket is damaged or missing.
b. Always properly install the filter/cartridge into the blower unit.
c. Keep inner circular sealing gasket clean.
d. Never attempt to clean filters by knocking or blowing out accumulated material. Doing so will damage the filter media.
e. Store the filter as described in these User Instructions within the recommended storage temperature conditions and
observe filter expiration dates.
The filter loading indicator is for particulate loading levels only. It does not provide any information about gas and vapor
service life. Attempting to use the filter loading indicator for gases and vapors may result in sickness or death.
The 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 can be used with either a high efficiency (HE) filter or
combination chemical cartridge/HE filter. The available filter and filter/cartridge options can be found at
www.3M.com/PPESafety or in the TR-600 Components, Accessories and Replacement Parts guide.
Particulate Filter Loading
The 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 Motor/Blower has a combination HE filter loading/low airflow
indicator (Fig. 14). This indicator is for particulate loading only; it does not apply to the service life of the carbon in
the chemical cartridge for the combination HE filter/gas and vapor cartridges. With a new HE only filter, all LEDs on
the indicator will light green. For certain combination HE filter/gas and vapor cartridges the inherent pressure drop, even on
a new cartridge/filter, may prevent the top LED on the filter loading indicator from being lit. As the HE filter becomes loaded,
the LEDs will begin to turn off. User must immediately leave the work area and the filter should be changed when the audible
alarm or a red LED activates or when the chemical cartridge service life is exceeded – whichever comes first. See the
Operating Instructions section of these User Instructions for further information on the HE filter/low airflow alarm.
Gas and Vapor Cartridge Service Life
The effective use time (service life) of a chemical cartridge (gas and vapor cartridge) will vary depending on your specific
environment. The user must determine a service life period based on their specific work conditions. The 3M Service Life
Software (www.3M.com/PPESafety) may be able to assist user in this calculation.
Prefilter/Spark Arrestor
Use of the foam prefilter (3M™ Prefilter TR-6600) and metal mesh spark arrestor/prefilter (3M™ Spark Arrestor TR-662) is optional
in many situations. They can be used individually or in combination. Both act by helping to block larger particles from reaching the
main filter, which may if changed (TR-6600) or cleaned (TR-662) frequently help to extend the useable life of the filter. The spark
arrestor may be cleaned by rinsing it under water. NOTE: Use of the spark arrestor is mandatory for welding and all situations
where the 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 may be exposed to sparks, molten metal or other
hot particulates. Failure to use the spark arrestor when needed may allow the filter to catch fire, or be damaged and allow
contaminants to enter the respirator. The foam prefilter and the metal mesh spark arrestor must be used with a filter cover.
Filter Covers
Filter covers are available for each size of filter. Use of filter covers are highly recommended. Filter covers help protect the filter
body and filter media from damage from external forces. The filter cover must be in place if operating the PAPR in a decon
shower or while being subject to liquid spray. The filter cover helps the PAPR resist water spray directed towards the wearer,
such as if going through a decon shower. The filter cover is required when using a prefilter or spark arrestor prefilter.
