Pureflo ESM Cleaning & Maintenance

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?

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

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

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

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

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

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

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

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!)

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.
