Run Times for Example Systems
TR-600-ECK (Easy Clean Kit): Run time: 9.5 – 12.5 hours
The pieces in the TR-600-ECK (Easy Clean Kit) that may influence run times include a TR-6710N HE filter, TR-6600
prefilter, BT-30 breathing tube, S-433L hood, and TR-630 standard capacity battery. The run time for the TR-600-ECK
using the supplied TR-630 standard capacity battery is between 9.5 hours and 12.5 hours, depending on the selected airflow
setting. If the TR-630 was replaced with the TR-632 high capacity battery, the run time would be between 13.5 hours and 19
hours, depending on selected airflow setting.
TR-600-HIK (Heavy Industry Kit): Run time: 10.5 – 15 hours
The pieces in the TR-600-HIK (Heavy Industry Kit) that may influence run times include a TR-6530N HE/OV/AG/HF
cartridge, TR-644 spark arrestor, BT-30 breathing tube, M-307 respiratory hardhat, and TR-632 high capacity battery. The
run time for the TR-600-HIK using the supplied TR-632 high capacity battery is between 10.5 hours and 15 hours,
depending on the selected airflow setting. If the TR-632 was replaced with the TR-630 standard capacity battery, the run
time would be between 7 hours and 10 hours.
System Run Times as Affected by Filter Loading
The 3M™ Versaflo™ PAPR TR-600 automatically compensates for the level of filter loading to help ensure the selected
airflow setting is delivered. A new clean (unloaded) filter has a lower pressure drop than a loaded filter, meaning it is easier
to draw air through a new filter than a loaded one. This also means that the PAPR system has to continuously work harder
and use more battery power to maintain a consistent airflow as the filter loads, which decreases the run time. There is an
inverse relationship between run time and filter loading, as shown in Figure 2.
When used in accordance with the
User
Instructions, the PAPR system works by filtering out air contaminants in the work
environments and delivering filtered air to the wearer. The characteristics and airborne concentration of each type of
contaminant influence how quickly a filter will load. Because of this, it is difficult to calculate how quickly a filter will load
in any given environment.

scale.
System Run Times as Affected by Battery Age
The available maximum capacity of a rechargeable battery decreases as the battery ages. 3M™ Versaflo™ battery packs
provide approximately 250 full capacity charge/discharge cycles while maintaining 80% of the original charge capacity over
the course of the first year of service when used under recommended conditions. As the battery ages its available capacity
decreases, which reduces the system’s run time per charge. For more information on battery aging and charge/discharge
cycle counting, see 3M Technical Data Bulletin #223 – Battery Maintenance for 3M™ Versaflo™ PAPR.
