Inspection, Cleaning, and Storage Procedures for 3M TR-300+

PAPR Assemblies

Introduction

The 3M™ Versaflo™ TR-300+ Powered Air Purifying Respirator (PAPR) assemblies are designed to be used with certain 3M

breathing tubes and headgear to form a complete respirator system.

Occupational use of respirators must be in compliance with applicable health and safety standards. By United States regulation

employers must establish a written respirator protection program meeting the requirements of the Occupational Safety and

Health Administration (OSHA) Respiratory Protection standard 29 CFR 1910.134 and any applicable OSHA substance specific

standard. OSHA 1910.134 states that employers shall ensure that respirators are inspected, cleaned, and properly stored.

This Technical Bulletin will review the 3M recommended cleaning procedures as well as inspection and storage guidelines for

the 3M™ TR-300+ PAPR assemblies. Refer to the TR-300+ PAPR User Instructions as well as the User Instructions for your

specific headgear for proper assembly, use and limitations of your specific respirator system.

Inspection

The 3M™ TR-300+ PAPR must be inspected before each use to ensure good operating condition. Detach the battery pack,

breathing tube, headgear, filter cover, filter, and prefilter or spark arrestor/prefilter (if used) from the motor/blower. If any

damage, non-functionality, or signal observations as noted below are discovered during the inspection, remove PAPR system

from use and service or replace as appropriate.

Motor/blower

IMPORTANT NOTE

Except for removing the filter cover, high efficiency filter, and prefilter or prefilter/spark arrestor the main housing of

the motor/blower cannot be opened and has no user serviceable parts.

• The filter cover must be intact with no cracks or other damage.

• The main housing or case of the motor/blower unit must be intact with no cracks, holes, or other damage. The plastic

should not be discolored, chalky, or soft as these may be signs of deterioration of the housing.

• The area of the motor/blower unit under the filter should be clean and free of contaminants. Contamination noted here may

indicate improper/lack of filter installation or damage to the filter or filter gasket.

• The user interface (motor blower display) should be clean. All LED segments should be lit and clearly visible during initial

start-up of the motor/blower. Excessive build-up of materials on the display may mask a visual alarm from the wearer. The

ON/OFF switch should be intact with no cuts, tears or holes.

• The filter release button should function smoothly and hold the cover securely onto the motor/blower.

• The outlet of the motor/blower (i.e. where the breathing tube attaches) should be inspected for any damage, dirt, debris,

or other contamination which may interfere with proper attachment of the breathing tube.

• The belt loops on the back of the motor/blower should be intact and undamaged.

Filters and Filter Accessories

• The high efficiency (HE) filter should be intact with no cracks, tears or other damage noted. If the filter is wet or appears

heavily loaded with particulate, it should be replaced. Never attempt to clean the filter by any means as intentional

manipulation can easily damage the filter media
