Assigned Protection Factor

Refer to the User Instructions for the specific head gear to be used to determine the assigned protection factor
(APF) for the TR-300 PAPR system. Consult 3M Technical Data Bulletin #175 for additional information on APFs and
supporting test data.

HE Filter, Prefilter, Spark Arrestor Service Life

The HE filter must be changed if the low airflow alarm is activated, the air flow as shown by the air flow indicator falls
below 6 CFM or the HE filter becomes damaged or wet. The TR-3600 should be replaced when it is dirty or damaged
and whenever the HE filter is replaced. The TR-362 should be replaced whenever it is damaged.
An excessively loaded HE filter, prefilter or spark arrestor/prefilter may also reduce battery pack run time. If run time is
shorter than expected replacing the filters may resolve the problem.

Range: 32°F (0°C) to 104°F (40°C)
NOTE: Consult a transportation specialist for any requirements or
limitations prior to transporting lithium ion battery packs.
Activates when airflow falls below 6 CFM (170 lpm) for greater than
approximately 30 seconds. If alarm condition continues (airflow remains
below 6 CFM) for approximately 15 minutes, the TR-300 system will
automatically shut down.
Activates when approximately 10-15 minutes of power remains. Power down
the motor/blower and replace the battery pack to reset alarm. This alarm
will also activate if the battery pack temperature reaches 130°F (55°C). See
Troubleshooting section of these User Instructions.
