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

The 3M™ Versaflo™ TR-300+ Powered Air Purifying Respirator (PAPR) is designed to be used with specific 3M breathing tubes and headgear to form a complete respirator system, providing respiratory protection in occupational settings. Its primary function is to filter ambient air and deliver clean, breathable air to the user's headgear, ensuring protection against particulates and other contaminants.

Function Description:

The TR-300+ PAPR system operates by drawing air through a high-efficiency (HE) filter, which removes airborne particulates. This filtered air is then delivered through a breathing tube to the user's headgear, creating a positive pressure environment within the headgear. This positive pressure helps prevent unfiltered air from entering the breathing zone, even if there are minor leaks in the headgear seal. The motor/blower unit is the core component, housing the fan that draws air and the electronics that control its operation. A rechargeable battery pack powers the motor/blower, providing portability and extended use. The system is designed for ease of use and maintenance, with clear indicators for battery status and filter condition.

Important Technical Specifications:

IP Rating: The TR-300+ PAPR has an International Protection (IP) rating of IP53 (EN 60529: 1992). This rating signifies protection against the infiltration of dusts and against water falling as a spray from overhead at an angle no more than 60 degrees on either side of vertical (up to 120 degrees total spread) that would interfere with normal operation. This allows for use in environments with moderate dust and light spray, and permits passage through decontamination showers under specific conditions.
Filter Type: The system utilizes a high-efficiency (HE) filter, designed to capture a wide range of particulate contaminants. Prefilters and spark arrestors are also available as accessories to extend the life of the HE filter and provide additional protection in specific work environments.
Battery Life: While not explicitly stated in terms of hours, the manual indicates that a fully charged battery pack should illuminate all five LEDs when the "Test" button is pushed, and fewer than five may suggest reduced capacity. Battery packs are designed for extended use, with recommendations for storage at approximately 40% charge to maximize pack life.
Operating Conditions: The system is designed for use in various occupational settings, with considerations for temperature and chemical exposure during storage and operation. Battery packs should not be used, charged, or stored where temperatures exceed 122°F (50°C).

Usage Features:

User Interface: The motor/blower unit features a clean user interface with LED segments that should be fully lit and clearly visible during initial start-up. This display provides visual alarms to the wearer. An ON/OFF switch controls the unit's operation.
Filter Release Button: A smooth-functioning filter release button ensures secure attachment and easy removal of the filter cover.
Breathing Tube Attachment: The outlet of the motor/blower is designed for proper attachment of the breathing tube, which should be inspected for any damage or contamination that might interfere with this connection.
Belt Loops: Integrated belt loops on the back of the motor/blower ensure secure attachment to the user's belt.
Decontamination Shower Compatibility: The TR-300+ PAPR, when assembled as a system with headgear and a breathing tube, can be worn through a decontamination shower with a spray angle of up to 60 degrees from vertical, provided it remains in a vertical (upright) position as worn around the waist. The unit can remain running or be turned off during the shower.

Maintenance Features:

Pre-use Inspection: Before each use, the PAPR system must be inspected. This includes detaching the battery pack, breathing tube, headgear, filter cover, filter, and prefilter/spark arrestor. Checks include inspecting for cracks, holes, discoloration, or softness of the motor/blower housing, filter cover, and battery pack. The HE filter should be inspected for cracks, tears, or wetness, and replaced if damaged or heavily loaded. The user interface LEDs and ON/OFF switch should be functional.
Cleaning Procedures:
- Motor/Blower and Battery Pack: Outer surfaces can be wiped with a soft cloth dampened in a solution of water and mild, pH-neutral detergent. Organic solvents, abrasive cleaners, compressed air, or vacuum cleaners should not be used. Liquid should not enter the outlet port or motor housing. The motor/blower and battery pack cannot be submerged or put in a respirator washer.
- Filters and Filter Accessories: The HE filter and foam prefilter cannot be cleaned and must be replaced if damaged or beyond service life. The metal spark arrestor/prefilter can be cleaned with a mild, pH-neutral cleaner and thoroughly dried.
Storage Guidelines:
- Motor/Blower: Store in a clean, contaminant-free environment, protected from prolonged exposure to heat, sunlight, radiation, and chemicals. For prolonged storage, the motor/blower should be run for 5 minutes at least once per year to ensure proper motor lubrication.
- Filters and Filter Accessories: Store HE filters, prefilters, and spark arrestors in their original 3M packaging at temperatures and conditions similar to the motor/blower. HE filters have a shelf life of 5 years. They should not be stored long-term on the motor/blower to prevent damage to the filter gasket.
- Battery Pack: Store off the charger with approximately 40% charge for storage greater than 30 days. Recharge before next use. For infrequently used packs, fully charge and then run down to 40% charge every 6 months.
Monthly Inspection for Emergency Use: Respirators used for emergency purposes require monthly inspection, including running the motor/blower, as per OSHA 29CFR1910.134.
