1. Pureflo ESM Cleaning & Maintenance

2. Pureflo ESM Respirator
Pureflo Respirators are NOT like any other Powered Air Purifying Respirator unit on the market
They have a HIGHER level of Protection – APF 1000
The Operator should always stay cleaner when using a Pureflo
WHY IS THIS?

3. Pureflo ESM Respirator What makes the Difference?
The NECKCAPE
But why is this?

4. Conventional PAPR
Lack of a Neck Cape means the inside of the helmet WILL get dirty and need cleaning.

5. Pureflo ESM Respirator Neck Cape
Provides a mechanical barrier to the filth
Enables HIGHER level of Protection
Provides a “stored” volume of respirable purified air
The entire inside of the helmet is the “Breathing Zone” as defined by OSHA

6. Breathing Zone The clean side of the Filters
Could be the inside of a Disposable or Half Mask Respirator
Conventional PAPR Respirators, the zone immediately in front of the mouth

7. Pureflo ESM with Neckcape
Major benefit of the neckcape is to prevent Gross Contamination in use of the inside of the helmet

8. VERY IMPORTANT! The inside of the helmet MUST be kept clean WHY?
This is the Breathing Zone
It contains the Air Flow Sensor that sends the control signals to the PCB that controls the motor providing the airflow

9. VERY IMPORTANT! Failure to keep the inside of the helmet clean will:
• Dramatically REDUCE the level of Respiratory Protection
• Contamination of the Air Flow Sensor will send false control signals to the PCB

10. Most common causes of Gross Contamination inside of the helmet.
• Incorrect use by Operators
• Careless temporary storage at break times
• Incorrect Cleaning Procedure (cleaning it like a conventional PAPR!)

11. Correct Use
Ensure headband is correctly adjusted, helmet is level and no more than “1 finger of forehead” is exposed
Visor Down!
Neckcape Drawstring Closed so that the neckcape puffs up like a balloon.

12. Correct Storage Break times, at the end of the Shift & after Cleaning
In hot climate wipe out excess sweat
Visor Down!
Neckcape Drawstring Closed!
Helmet Sat Upright!

13. Correct Cleaning – Cardinal Rules!
ALWAYS Clean Gross Contamination from the outside of the unit BEFORE disassembly or removing the filter
NEVER use compressed air on any part of the respirator
NEVER immerse respirator in liquid
Visor Down!
Neckcape Drawstring Closed!

17. Correct Cleaning
In extremely dusty environment dry wipe excessive dust from helmet & collar or vacuum
Do NOT use compressed air

18. Correct Cleaning
Sit unit on a Draining Board and use a damp sponge and mild liquid detergent solution to clean the outside of the respirator

19. Correct Cleaning
For ingrained dirt on the outside of the respirator, use a nail brush, ultrasonic brush or scouring pad
*not on the visor

20. Correct Cleaning Rinse with a clean damp sponge
Dry unit before disassembly

21. Correct Cleaning
Remove filter with the filter at the lower most point. This will ensure any dislodged dirt particles fall away from the respirator

22. Correct Cleaning
Wipe motor plenum with Purewipes or similar Iso Propyl Alcohol.
NEVER immerse in liquid

23. Correct Cleaning Remove neckcape and hand wash with liquid soap.
Machine wash with laundry soap, warm water, and hang to air dry or tumble dry with no heat

24. Correct Cleaning
Remove interior comfort pads and put into laundry

25. Correct Cleaning
Remove batteries if they are to be re-charged remotely. Leave if they are to be charged in situ.
In either event, wipe with Purewipes or similar Iso Propyl Alcohol wipes.

26. Correct Cleaning
Remove suspension assembly and dry wipe all sweat from inside of helmet.
Do not use spray bottles or apply excessive amounts of cleaning solution to towels

27. Correct Cleaning
Wipe all internal surfaces of the helmet with Purewipes or similar Isopropyl Alcohol wipes.
NEVER immerse in liquid

28. Correct Cleaning
If inside of PAPR is wet from cleaning store in a dry, clean, well ventilated area prior to reassembly
Re-assemble Pureflo unit with new or newly laundered Comfort Pads and Neckcape
Fit new or Re-fit filter. Ensure this is done with the filter at the lowest point to ensure dislodged particles cannot fall into the respirator

29. Correct Storage Remember: Inside helmet should be dry prior to storage
Visor Down!
Neckcape Drawstring Closed!
Helmet Sat Upright!
