2. Description
2.1 System Overview
The Pureflo Models PF50ESM+ (bump cap and the P-Series or Pharmaceutical variant) and
PF60ESM+ (hardhat model) are self-contained powered air purifying respirator (PAPR).
2.2 Components
2.2.1 Powered Air Purifying Respirator unit (PAPR)
The Pureflo incorporates an Electronic Systems Management (ESM) which monitors both the filter
state and battery power assuring continuous airflow above 170 lpm for the entire period of use. Should
airflow or power drop, these units will alert the user.
2.2.2 Filter(s) and Cartridge(s)
The Pureflo Models PF50ESM+ and PF60ESM+ should only be used with original Pureflo ESM filters.
When equipped with a High Efficiency Particulate Air (HEPA) HE filter (order number PR02020SP), they
are effective against solid and liquid aerosols (particulates).
When equipped with an HE/HF/HC cartridge (order number PR02026SP), these respirators are effective
against Hydrogen Chloride (HC) and Hydrogen Fluoride in addition to particulates. This cartridge is
also effective for nuisance level removal of most organic vapors, inorganic vapors, acid gases and
ozone, where ‘nuisance level’ refers to concentrations not exceeding the OSHA PEL or other applicable
government occupational exposure limits, whichever is lower. NIOSH does not approve filters for
Nuisance level protection.
The use of any other filter(s) is prohibited.
2.2.3 Rechargeable Battery Pack
The Pureflo ESM+ is powered by rechargeable battery packs held inside the respirator
2.2.4 Battery Charger
The Pureflo ESM+ comes with two (2) battery chargers (part number PR02230).

Visor Lock Installation
1. Refer to the pictures above and identify the top side, the Over-Visor locking channel, and the tail end of
the visor clip.
2. Ensure the visor is completely in the down position during the following steps.
3. Refer to drawing of figure above; locate the center of the rubber gasket attached to the primary
visor and using your fingers, pull outward and downward and hold. Identify the visor lock insertion
channel in the main chassis.
4. Ensure the visor locking channel is facing down toward the top of the visor and fully insert the tail
end of the visor clip into the slot of the unit’s frame.
5. With your fingers, simultaneously push the top of the visor downward and lift the locking clip
upwards. Pull outward on the visor to locate the visor into the visor locking channel of the clip.
Release the rubber gasket.
Visor Lock Removal
1. Repeat step 3 from above.
2. Using your fingers, push downward on the top of the visor and lift the locking clip upward. The visor
should release from the locking channel but may require inward pressure on the top of the visor
while lifting the locking clip upward.
3. Slide the locking clip out from the slot of the main frame.
4. Release the rubber gasket.

2.2.6 Storage Bag
The Pureflo ESM+ comes with one (1) Storage Bag (part number 838003).
2.2.7 Instructions for use USA/Canada
The Pureflo ESM+ comes with one (1) Instructions for Use- this document.
2.2.8 Product Limited Warranty
The Pureflo ESM+ comes with one (1) Product Limited Warranty card (part number QC057).
2.3 Functional Description
The powered air purifying respirator is a respiratory protective device depending on circulating air.
It filters the ambient air and makes it available as breathable air. The device continuously takes in
ambient air through the filter. The filter absorbs harmful particulates. In this way, the ambient air is
recycled and finally reaches the face/breathing zone. There it is available as breathable air.
An adjustable neck cape ensures that continuous positive pressure is maintained within the respirator,
preventing ambient air from penetrating.
The Pureflo ESM+ provides head, face and eye protection. (Depending on the installed accessory
components)
The Pureflo ESM+ is powered by rechargeable battery packs held inside the respirator.
The Pureflo ESM+ contains an adjustable headband and crown strap ensuring a comfortable fit for most
head sizes from sizes.

2.3.1. Warning Devices
Malfunctions during operation are indicated by warning devices.
The warning devices include:
•optical warning (LED status indicator on the right inside of the helmet)
•acoustic warning (sounder)
If in the fan unit is no longer able to deliver the default flow rate (e.g. due to increasing saturation of the
particle filter), a warning is triggered.
2.4 Intended use
When equipped with a HE filter (Order number PR02020SP), they protect against solids and liquid
aerosols (particulates).
When equipped with an HE/HF/HC cartridge (Order number PR02026SP), these respirators are effective
against solid and liquid aerosols (articulates), Hydrogen Fluoride (HF) and Hydrogen Chloride (HC). This
filter is effective for nuisance level of most Organic Vapors, Inorganic Vapors, Acid Gases and Ozone,
where ‘nuisance level’ refers to concentrations not exceeding OSHA PEL or other applicable

19
government occupational exposure limits, whichever is lower. NIOSH does not approve filters for
Nuisance level protection.
Note that the Pureflo ESM+ does not monitor remaining service life for HF, HC, or other vapors or
gases. Users must determine an appropriate cartridge change out schedule.
2.5 Limitations on use
The device is not suitable for use:
•in atmospheres that are oxygen deficient;
•where contaminant concentrations are unknown;
•where contaminant concentrations are Immediately Dangerous to Life or Health (IDLH);
•where contaminant concentrations exceed the maximum use concentration (MUC) determined
by using the Assigned Protection Factor (APF) for the specific respirator system or the APF
mandated by specific government standards, whichever is lower;
•in unventilated areas;
•outside the intended temperature range of 40°F to 105°F (+5°C to +40°C);
WARNING
Immediately exit the contaminated area if any of the low battery or low airflow alarms activate.
The recommended altitude range of the PureFlo ESM+ is approximately sea level to 2600 feet (800
meters).
2.6 Respiratory Program Management
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 standards. For additional
information on this standard contact OSHA at www.OSHA.gov. In Canada, CSA standard Z94.4
requirements must be met and/or requirements of the applicable jurisdiction as appropriate.
