• The 3M™ Battery Charger Cradle TR-640 can remain attached to the 3M™ 4-Station Battery
Charger 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. Be careful not to pinch fingers as the cradle slides forward.
Refer to the "Storage" section in these User Instructions for information on short and long-term storage
of the TR-630 and TR-632 battery packs.
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. 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 and may result in injury, sickness
or death.
f. Store the filter as described in these User Instructions within the recommended storage
temperature conditions and observe filter expiration dates.
g. 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/workersafety 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. 14-5). 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/workersafety) may be able
to assist user in this calculation.
