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.
Install HE filter and if using, the TR-3600 prefilter or TR-362 spark arrestor/prefilter:
1. Inspect the HE filter to be installed:
° Filter material is intact with no tears, cracks, distortion or other damage.
° The bottom gasket(s) are intact with no cuts, distortions or indentations. Wipe the filter seal with a clean cloth if
necessary. Dispose of and replace filter if damage is noted or suspected.
2. With the unit off, remove the filter cover. Do not replace the filter, prefilter, or spark arrestor/prefilter with the
unit running.
° Hold the unit so the filter cover faces you
° Press the cover latch on the right side and lift off (Fig. 5).

3. Place the HE filter and the prefilter or spark arrestor (if either is being used) into the filter cover according to Fig
6. Ensure the HE filter label can be seen in the filter cover view window. NOTE: 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.

4. Reinstall the filter cover in the TR-300 unit:
Hook the left side of the filter cover into the left side of the TR-300 unit.
°
Press down on the right side of the cover until the latch fully engages.
°
The HE filter label must be visible through the filter cover window (Fig. 11).

Removal of HE filter, prefilter or spark arrestor
Ensure the unit is off. Do not replace the filter, prefilter, or spark arrestor with the unit running. Repeat step 2
in the previous section, Installing the filter, to access the HE filter and if using the prefilter or spark arrestor. Remove
each by lifting out. Alternatively the user may wish to hold the PAPR motor blower facing downward (cover towards the

ground) during removal of the cover and filters. This will help minimize the potential for contamination of the interior of
the motor blower during cover and filter removal.
Filter Notes
° The HE filter may be left in place on the motor/blower for storage. Alternatively, remove the HE filter and seal dry in
a closed container.
Filter Surround Gasket (optional)
The TR-380 Filter Surround Gasket may be used in conjunction with a complete TR-300 system to help facilitate
cleaning of the motor blower unit by helping to reduce dust and particles from accumulating around the edges of the
filter housing. The filter surround gasket does not affect the filtration capability of the system. To install:
1. Remove and discard center support (A) from filter surround gasket (B) (Fig. 7a).
2. Carefully fit the filter surround gasket around the filter (Fig. 7b).
3. Place filter with filter surround gasket into the filter cover (Fig. 7c). Carefully tuck filter surround gasket material
between the top of the filter cover and filter housing.
4. Install filter as directed, being certain the hinge side of the filter cover is set in the motor/blower prior to latching (Fig. 7d).

Breathing tube

Select an approved breathing tube.
1. Insert the end of the breathing tube with the bayonet fitting (two small prongs) into the parallel slots in the air outlet
of the motor/blower (Fig. 8).
2. Twist the breathing tube 1/4 turn to the right to lock it into place.
3. Refer to the User Instructions for the headgear to be used for procedures to connect the breathing tube to the
head gear.
