Step Down Feature
To conserve battery power when in the high airflow setting, the motor/blower will automatically step down to the standard
airflow setting when the filter loading reaches approximately 90% or the battery run time remaining is less than 4 hours.
This can be over-ridden by the user by pressing the flow control button to move the airflow back to high flow. The low
battery alarm and low flow alarm will always operate as described above, when either alarm sounds, users must
immediately exit the hazardous area and replace either the battery or filter, whichever alarm is activated.

INSPECTION

Failure to follow these User Instructions may reduce respirator performance, overexpose you to
contaminants, and may result in injury, sickness, or death.
a. Do not use with parts or accessories other than those manufactured by 3M as described in these User
Instructions or on the NIOSH Approval Label for this respirator.
b. The 3M™ Versaflo™ Powered Air Purifying Respirator TR-300+ Assembly is one component of an approved
respiratory protection system. Always read and follow all User Instructions supplied with your 3M™ Headgear
and other system components in order to ensure correct system operation.
c. Do not turn off the motor/blower, remove the facepiece or headgear, or reach your hand into the headgear while
inside the contaminated area. This could allow contaminants to enter the respirator and may result in sickness
or death.
Before each entry into a contaminated area, the following inspection must be performed to help ensure proper function
of the respirator system. Respirator systems are intended to help reduce exposures to certain contaminants and
should always be handled with care and fully inspected prior to use. Refer to the specific "Assembly" subsection of
these User Instructions for proper assembly procedures.
1. PAPR system:
• Closely inspect the entire PAPR system including the motor/blower, cover, filter/cartridge, breathing tube,
battery, belt, and headgear. Pay particular attention to component connection points for wear or damage. If parts
are missing or damaged, replace them only with 3M™ Versaflo™ Powered Air Purifying Respirator TR-300+
Replacement Parts before proceeding.
2. Filter:
• Closely inspect filter plastic housing including the corners and latches, outer rectangular barrier, and inner
circular filter seal gasket for cracks, tears, cuts, distortion, indentations or debris. Replace filter/cartridge if
damaged. If the filter/cartridge has been mishandled or dropped, re-inspect fully. If you have any concerns,
contact 3M Technical Service for guidance.
• Ensure the filter is properly installed in the cover and then on the PAPR unit.
• If sparks or other hot particles are present, the spark arrestor must be in place in front of the filter and prefilter
(if used). Failure to use the spark arrestor when needed may allow the filter to catch fire, or be damaged and
allow contaminants to enter the respirator, and may result in injury, sickness, or death.
