High Efficiency (He) Particulate Filter, Prefilter And Spark Arrestor - 3M Versaflo TR-300 Series User Instructions

High Efficiency (HE) Particulate Filter, Prefilter and Spark Arrestor

A 3M TR-300 high efficiency (HE) filter must always be used. The TR-3600 prefilter is an optional accessory for select
3M hoods and headcovers. Check the TR-300 NIOSH approval label to determine if the prefilter is approved for use
with your specific system configuration. The TR-362 is a spark arrestor/prefilter for select 3M industrial headgear
and 3M Speedglas welding headgear. Check the TR-300 NIOSH approval label to determine if the spark arrestor/prefilter is
approved for use with your specific system configuration. Use of the TR-362 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/prefilter may allow the filter to catch fire, or be damaged and allow contaminants to enter the respirator.
The TR-3600 cannot be used in combination with the TR-362. Refer to the TR-300 NIOSH approval label to confirm
which product can be used with your system configuration. If there is any question regarding use of the HE filter,
prefilter or spark arrestor/prefilter consult a supervisor, occupational safety and health professional or call the 3M
Technical Service help line.
