High Effi ciency (HE) Particulate Filter, Prefi lter and Spark Arrestor
A 3M™ TR-300 high effi ciency (HE) fi lter must always be used. The TR-3710N and TR-3710N-SG
are standard HE fi lters. The 3M™ TR-3810N and TR-3810N-SG HE fi lters are 3M recommended for
relief against nuisance level organic vapors. Nuisance level organic vapor refers to concentrations not
exceeding OSHA PEL or applicable government occupational exposure limits, whichever is lower.
The TR-3600 prefi lter is an optional accessory for select 3M™ hoods and headcovers. Check the
TR-300 NIOSH approval label to determine if the prefi lter is approved for use with your specifi c system
confi guration.
The TR-362 (TR-362-SG) is a spark arrestor/prefi lter for select 3M™ industrial headgear and 3M™
Speedglas™ welding headgear. Check the TR-300 NIOSH approval label to determine if the spark
arrestor/prefi lter is approved for use with your specifi c system confi guration. Use of the TR-362 or
TR-362-SG is mandatory for welding and in all situations where the TR-300 may be exposed to sparks,
molten metal, or other hot particulates. Failure to use the spark arrestor/prefi lter may allow the fi lter to
be damaged and allow contaminants to enter the respirator.
The TR-3600 cannot be used in combination with the TR-362 or TR-362-SG.
Refer to the TR-300
NIOSH approval label to confi rm which product can be used with your system confi guration. If there
is any question regarding use of the HE fi lter, prefi lter or spark arrestor/prefi lter consult a supervisor,
occupational safety and health professional or call the 3M Technical Services help line.
Install HE fi lter and if using the TR-3600 prefi lter or TR-362 (TR-362-SG) spark arrestor/prefi lter:
1. Inspect the HE fi lter to be installed:
o
Filter material is intact with no tears or other damage.
o
Filter seal is present and intact with no particles, cuts, distortions or indentations present. Wipe
the fi lter seal with a clean cloth if necessary. Dispose of and replace fi lter if damage is noted or
suspected.
