System Description

Before use, the wearer must read and understand these User Instructions. Keep these User Instructions for reference.

This product is part of a system that helps protect against certain airborne contaminants. Misuse may result in sickness or death. For proper use, see supervisor, User Instructions or call 3M in U.S.A., 1-800-243-4630. In Canada, call Technical Service at 1-800-267-4414.

The 3M™ Versaflo™ Powered Air Purifying Respirator (PAPR) TR-300 Assemblies are part of the 3M™ Versaflo™ Family of respiratory protection products. The Versaflo TR-300 PAPR assemblies are designed to be used with the 3M headgear listed on the approval label to form a complete National Institute of Occupational Safety and Health (NIOSH) approved respiratory system. When used in accordance with its NIOSH approval, TR-300 PAPR assemblies help provide respiratory protection against particulates. The TR-300 does not provide protection against vapors or gases and is not an intrinsically safe system. See NIOSH Approval section of this User Instruction for additional information on approvals.

The TR-300 belt mounted assemblies consist of a motor/blower unit, high efficiency filter, waist belt, and lithium ion battery pack. The motor/blower unit draws ambient air through its high efficiency filter and supplies filtered air to the headgear via a breathing tube. The blower unit is equipped with automatic flow control; the motor speed is regulated during operation to compensate for the charge state of the battery pack and the increasing level of airflow resistance caused by filter loading. Should the airflow fall below the minimum design flow rate, an audible alarm will sound and the red fan shape LED on the blower unit user interface will flash to warn the user to immediately leave the contaminated environment. Similarly an audible and visual low battery alarm will activate when the battery pack has approximately 10-15 minutes of charge remaining to warn the user to leave the contaminated area.

The TR-300 is available with a variety of accessories, belt options, and choice of standard or high capacity battery pack and single or multi-station charger. Consult the Listing of Components, Accessories, and Replacement Parts in this User Instruction for additional information including a listing of Versaflo TR-300 PAPR part numbers.

Properly selected, used, and maintained respirators help protect against certain airborne contaminants by reducing concentrations in the wear's breathing zone below the Occupational Exposure Limit (OEL). It is essential to follow all instructions and government regulations on the use of this product, including wearing the complete respirator system during all times of exposure, in order for the product to help protect the wearer. Misuse of respirators may result in overexposure to contaminants and lead to sickness or death. For proper use, see supervisor, refer to the product User Instructions or contact 3M Technical Service at 1-800-243-4630. In Canada, call Technical Service at 1-800-267-4414.

High capacity – TR-332	Approximately 8 -12 hours* * Estimated system run time based on testing with a new battery and a new clean filter at 68ºF (20ºC). Actual system run time may be extended or shortened depending on system configuration and environment.
Time to recharge:
Standard – TR-330	< 3.0 hours
High capacity – TR-332	< 3.5 hours
Internal charging temperature	Optimal: 60ºF (20ºC) to 95ºF (35ºC) Range: 32ºF (0ºC) to 104ºF (40ºC) NOTE: Consult a transportation specialist for any requirements or limitations prior to transporting lithium ion battery packs.
Motor/blower Alarms:
Low air flow	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.
Low battery pack voltage	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.
System Alarm	Audible alarms – 85 dBA at 4 inches (10 cm)
Intrinsic Safety	The TR-300 assembly is not an intrinsically safe system.
Latex	The TR-300 assembly does not contain dry or natural rubber latex

For additional specifications refer to the 3M™ Versaflo™ Powered Air Purifying Respirator TR-300 Technical Specifications sheet.

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.
