3M ADFLO (01) PDF DOCUMENT

The 3M ADFLO PAPR Assembly is designed to be used with certain 3M™ Headgear to form a complete NIOSH approved respiratory system. When used in accordance with its NIOSH approval, 3M ADFLO PAPR Assemblies can help provide respiratory protection against certain particulates, organic vapors and acid gases.

The assembly consists of a blower unit, high efficiency filter, waist belt, breathing tube, and lithium-ion battery pack. Optional components like a nuisance odor pad assembly and an acid gas/organic vapor cartridge are also available. The motor/blower unit draws ambient air through its filter/cartridge and supplies filtered air to the headgear via a breathing tube.

The blower motor speed is automatically regulated to compensate for the battery’s charge state, particle filter loading, and higher altitudes. The system includes audible and visual alarms for low airflow and low battery to warn the user to leave the contaminated environment.

1. The 3M ADFLO PAPR 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 to ensure correct system operation. Failure to do so may result in injury, sickness, or death.

2. The 3M ADFLO PAPR System is not intrinsically safe. Do not use in flammable or explosive atmospheres; doing so may result in serious injury or death.

3. Always correctly use and maintain the lithium-ion battery packs. Failure to do so may cause fire or explosion or could adversely affect respirator performance and result in injury, sickness, or death. This includes not charging with unapproved chargers, not using outside recommended temperature limits, charging in a safe area, using only the specified 3M ADFLO charger, and preventing water from entering the battery case.

4. Dispose of lithium-ion battery packs according to local environmental regulations. Do not crush, disassemble, dispose of in standard waste bins, in a fire, or send for incineration.

5. Do not repair or modify any component of this system or use it with parts not manufactured by 3M as described in the user instructions.

6. Always correctly use and maintain the filter assembly. This includes inspecting the filter and seal before each use, not pressing on the filter grill during installation, keeping the seal clean, and never attempting to clean filters by knocking or blowing out material.

7. The filter-loading indicator reflects particle clogging only and does not provide information about gas & vapor service life.

8. The nuisance odor pad should only be used for concentrations of organic vapors not exceeding the OSHA permissible exposure limit (PEL) or applicable government limits, whichever is lower.

9. The service life of the optional organic vapor/acid gas cartridge must be pre-determined. It must be replaced according to a change-out schedule or if contaminants are detected.

10. Do not use the 3M ADFLO PAPR system with a heavily loaded spark arrestor or without the spark arrestor screen properly installed, as it may damage the filter or cause the filter/blower housing to ignite.

Do not wear the 3M ADFLO respirator system to enter areas where:

• Atmospheres are oxygen deficient.

• Contaminant concentrations are unknown.

• Contaminant concentrations are Immediately Dangerous to Life or Health (IDLH).

• Contaminant concentrations exceed the maximum use concentration (MUC) determined using the Assigned Protection Factor (APF) for the specific respirator system or the APF mandated by specific government standards, whichever is lower.

Additionally, you must immediately exit the contaminated area if any of the low battery or low airflow alarms activate. The OV/AG cartridge and nuisance odor pad assembly must always be used with the HE filter, pre-filter, and spark arrestor. Do not use them alone or in combination with one another.

• Below 5000 feet mean sea level (MSL), the 3M ADFLO PAPR can be used with the HE Particulate Filter by itself or in combination with the Nuisance Odor Pad Assembly or Organic Vapor/Acid Gas Cartridge.

• Between 5000 feet and 10,000 feet MSL, the 3M ADFLO PAPR should only be used with the HE Particulate Filter.

A. Not for use in atmospheres containing less than 19.5 percent oxygen.

B. Not for use in atmospheres immediately dangerous to life or health.

C. Do not exceed maximum use concentrations established by regulatory standards.

F. Do not use powered air-purifying respirators if airflow is less than four cfm (115 lpm) for tight-fitting facepieces or six cfm (170 lpm) for hoods and/or helmets.

H. Follow established cartridge and canister change schedules or observe ESLI to ensure that cartridge and canisters are replaced before breakthrough occurs.

I. Contains electrical parts that may cause an ignition in flammable or explosive atmospheres. J – Failure to properly use and maintain this product could result in injury or death.

L. Follow the manufacturer’s User’s Instructions for changing cartridges, canister and/or filters.

O. Refer to User’s Instructions, and/or maintenance manuals for information on use and maintenance of these respirators.

P. NIOSH does not evaluate respirators for use as surgical masks.

New 3M ADFLO battery packs should be charged upon receipt. The battery can be charged separately or while attached to the PAPR Assembly. A full charge takes approximately 6.5 hours.

1. Inspect the battery pack before each charge. If any cracks or damage are noted, do not charge it. Replace it and dispose of it properly.

2. Place the charger and battery pack in a cool, well-ventilated location free of airborne contaminants.

3. Connect the charger output into the battery’s charging socket.

4. Plug the charger into a suitable source of AC power (110-120V).

IMPORTANT: 3M recommends disconnecting the battery pack from the charger once it is fully charged. Leaving the battery pack connected for prolonged periods may damage the battery cells. A fully charged battery can be left in trickle-charging mode for a short time (3-4 days).

The 3M ADFLO PAPR motor/blower has a three-bar battery indicator that is operational when the unit is turned on.

• Three solid bars: 80-100% capacity

• Two solid bars: 20-80% capacity

• One solid bar: 5-20% capacity

• Flashing bottom bar: Less than 5% capacity (approximately 15-30 minutes of charge remaining). The audible alarm will also sound.

To install the battery pack:

1. Inspect the hinge and latch on the battery pack to ensure they are clean and undamaged.

2. Hook the left edge of the battery pack into its holder on the bottom of the unit and press the battery pack into the motor/blower until the catch fully engages with two audible clicks.

3. Gently tug on the battery pack to verify it is secure.

To remove the battery pack:

Press the battery pack latch on the right of the battery pack. Pull the battery pack down and out.

The high efficiency (HE) filter, pre-filter, and spark arrestor must always be used with the 3M ADFLO system.

• Pre-filter: Designed to extend the service life of the HE filter by capturing larger particles. It CANNOT be cleaned and must be replaced.

• Spark Arrestor: A metal screen that should be inspected each time the filters are changed. If it is dirty, it can be cleaned with a solution of clean water and mild detergent. Dry it completely before reinstalling. If damaged, replace it with a new one.

• HE Filter: CANNOT be cleaned. Do not attempt to remove contamination from the HE filter or pre-filter using compressed air or other means. Replace when necessary.

1. Inspect the HE filter to be installed. Ensure the filter material is intact and dry, and the filter gasket is present and intact with no damage. Wipe the gasket with a clean, dry cloth if dirty. Dispose of and replace the filter if any damage is noted.

2. Remove the filter cover.

3. Place the spark arrestor, pre-filter, and HE filter into the filter cover. Ensure the ribs on the HE filter are aligned with the slots on the latch side of the filter cover. Ensure all components are squarely seated. Do not press on the filter grill when installing.

4. To reinstall the filter cover, hook the left side of the filter cover into the left side of the 3M ADFLO PAPR. Press down on the right side of the cover until the catch fully engages with an audible click.

The filter components are identified as follows:

The OV/AG cartridge and nuisance odor pad assembly must always be used with the HE filter, pre-filter, and spark arrestor.

1. Remove the filter cover.

2. Inspect the HE filter, pre-filter, and spark arrestor, replacing as needed.

3. Inspect the OV/AG cartridge or nuisance odor pad assembly. Ensure the gasket is present and intact. Wipe clean if dirty, or dispose of and replace if damaged.

4. Place the spark arrestor, pre-filter, and HE filter into the filter cover, ensuring proper alignment.

5. Hook the left side of the OV/AG cartridge or nuisance odor pad assembly into the left side of the PAPR and press the cartridge down until its catch engages with an audible click.

6. Reinstall the filter cover assembly by hooking its left side into the left side of the OV/AG cartridge. Press down on the right side of the cover until the catch fully engages with an audible click.

The nuisance odor pad can be replaced by pressing the expired pad out of the assembly from the backside (the side with the gasket). It is easiest to press on the vertical edges nearest the frame. Once the old pad is removed, install a new nuisance odor pad by pressing it into the assembly. Replace the pad when smell or taste occurs.

1. Select an approved breathing tube for the headgear to be used.

2. Inspect the PAPR end of the breathing tube to confirm the rubber “O” ring is in place and not damaged. Replace if missing or damaged.

3. Insert the 2 prongs on the PAPR end of the breathing tube into the parallel slots in the air outlet of the motor blower and twist 1/4 turn to the right to lock it into place.

1. Remove the old belt from the 3M ADFLO PAPR by unfastening the belt’s two hook and loop straps and pulling the PAPR away from the belt.

2. To replace the belt:

a. Thread each hook and loop strip through the slot on the back of the unit, and then through the slot on the leather belt. The “UP” arrow on the unit should be pointing towards the top.

b. Tightly pull the two hook and loop strips before fastening them to one another. When attached properly, the PAPR will sit tight against the belt and stay in place.

To turn ON:

Press and hold the ON button on the top of the motor/blower for 2 seconds. The unit will perform a self-diagnostic. All three LEDs (2 green, 1 red) on the power switch and the audible alarm will come on for 1 second, after which the 2 green LEDs will remain on. The Battery Pack and filter LEDs will light up sequentially to show the current status of each.

To turn OFF:

Press and hold the OFF button on the top of the motor/blower for 2 seconds. The red LED will come on, and the audible alarm will sound for 1 second as the unit turns off.

Visual Inspection:

1. PAPR Assembly: Visually inspect the entire assembly, including the motor/blower, cover, filter/cartridge, breathing tube, battery pack, belt, and headgear. Replace any missing or damaged parts with genuine 3M ADFLO replacement parts.

2. Battery Pack: Confirm the battery is fully charged and securely latched to the motor/blower.

3. Breathing Tube: Examine the entire tube for tears, holes, or cracks. Ensure the o-ring on the PAPR end is present and intact.

4. Filter/Cartridge: Inspect the pre-filter and spark arrestor to ensure they are intact and clean. Inspect the HE filter and gasket for damage. Ensure the filter cover is securely latched. If using a nuisance odor pad or chemical cartridge, ensure it is securely attached.

Air-flow Check:

After the visual inspection, you must perform an air-flow check to ensure the unit is providing adequate airflow.

1. Ensure the ball in the flow indicator (15-0099-05 or 15-0099-21) moves freely in its tube. Rinse with clean water if stuck, and allow to dry completely.

For standard breathing tubes (using 15-0099-05 Indicator):

2. Insert the breathing tube into the air outlet.

3. Turn the 3M ADFLO PAPR on.

4. Insert the airflow indicator onto the end of the breathing tube.

5. Allow the PAPR to run for 2 minutes to stabilize airflow.

6. With the indicator held vertically, ensure the bottom of the ball rests at or above the minimum flow mark. If it fails, refer to the troubleshooting guide.

7. Check the low airflow alarm: With the PAPR on, remove the indicator and tightly cover the end of the breathing tube with your palm. The motor will speed up. After 15-30 seconds, an audible alarm will sound and the red LED on the ON/OFF switch will light up. Remove your hand; the alarm and LED should stop.

For L-122SG breathing tube (using flow indicator adapter):

8. Insert the airflow indicator adapter onto the end of the Air Flow Indicator.

9. Insert the adapter unit into the outflow port on the PAPR.

10. Turn the PAPR on and let it run for 2 minutes.

11. Hold the indicator vertically at eye level and ensure the ball is at or above the minimum flow mark.

12. Check the low airflow alarm as described in step 7 above, but cover the PAPR outflow port with your palm instead of the breathing tube end.

If the PAPR does not operate as described, refer to the troubleshooting guide before use.

Prior to entering the contaminated area, complete the full pre-use inspection procedures.

1. Turn the motor/blower on.

2. Check the airflow and alarms.

3. Don the 3M ADFLO PAPR Assembly and headgear. Enter the work area.

4. Leave the contaminated area immediately if any of the specified conditions occur (e.g., system damage, low airflow, alarms).

5. Do not remove the respirator or reach inside the headgear while in the contaminated area.

6. Follow your facility’s specific exiting and decontamination procedures for turning off and removing the respirator system.

Leave the contaminated area immediately if any of the following conditions occur:

a. Any part of the system becomes damaged.

b. Airflow into the respirator decreases or stops.

c. The low airflow or low battery alarms trigger.

• The airflow alarm activates when flow falls below 6 CFM (170 lpm) for more than 15-30 seconds. The PAPR will shut down 2 minutes after continuous alarm activation.

• The battery alarm activates in the last 15-30 minutes of charge. The bottom battery LED will flash, and an audible alarm will beep. In the final 15-60 seconds, the alarm will fast beep, and the unit will shut down 30 seconds after the quick beep starts.

d. In the event only an audible or only a visual alarm triggers, the user should still immediately leave the contaminated area.

e. Breathing becomes difficult.

f. You feel dizzy or your vision is impaired.

g. You taste or smell contaminants.

h. Your face, eyes, nose or mouth become(s) irritated.

i. You suspect that the concentration of contaminants may have reached levels at which this respirator may no longer provide adequate protection.

Cleaning:

To avoid damage, do not use solvents for cleaning. Do not immerse in water or spray directly with water. Detach the battery pack, breathing tube, and headgear before cleaning.

1. Motor/blower and battery pack: Clean the outer surfaces with a soft cloth dampened in a solution of water and mild, pH-neutral detergent. Ensure electrical contacts are dry.

2. Breathing tube: Clean the exterior and connection sites with the water and detergent solution. Ensure the tube is completely dry before using or storing. The L-122SG and SG-50W breathing tubes contain sound-absorbing material and cannot be immersed in liquids; they must be replaced if wet.

3. HE filter: Open the filter cover and inspect the HE filter, pre-filter, and spark arrestor. Replace if excessively dirty, wet, or damaged. The HE and pre-filters cannot be cleaned. The spark arrestor can be cleaned with a cloth and mild detergent solution and must be completely dry before reinstallation.

Storage:

• Motor/Blower: Store at a temperature between -4°F to 131°F (-20°C to 55°C) in a clean environment out of direct sunlight.

• Battery Pack: Store at -4°F (-20°C) to 115°F (45°C), R.H. < 85%. For long-term storage, disconnect from the motor/blower. Battery packs not in regular use should be charged upon receipt and placed on a regular recharge schedule (every 3 months of non-use) to prevent cell damage.

Charger LED Codes:

• Chemical Cartridges: The useful service life of the 3M ADFLO PAPR Organic Vapor/Acid Gas Cartridge depends on the specific type, volatility, and concentration of contaminants, as well as environmental conditions like humidity and temperature. Replace cartridges according to an established change schedule, regulations, or sooner if smell, taste, or irritation from contaminants is detected.

• Nuisance Odor Pad Assembly: The service life depends on environmental conditions and contaminant concentration. It should only be used for organic vapor concentrations not exceeding the OSHA PEL. Replace if smell or taste is detected.

• Particle Filter: The 3M ADFLO motor/blower has a five-step particle filter-loading indicator (three green, two red). Each illuminated light signifies increased filter clogging. When the red indicator(s) are lit, battery run time is significantly reduced, and replacement of the HE filter and pre-filter is recommended. The HE filter should also be changed if it becomes wet or damaged, if battery pack operating time is shortened, or if the low airflow alarm is activated. The pre-filter should be changed at least as frequently as the HE filter.
