e-breathe e-Flow
1. General Information
The e-breathe e-Flow system is a battery-powered blower unit which is, along with respiratory filters, a breathing hose
and a head piece, part of a blower-assisted breathing system in accordance with EN 12941: 2009 or EN 12942: 2009.
The blower is equipped with filters. The e-breathe e-Flow is a respirator system designed to supply filtered air for use
in dangerous environments. Air is drawn through the filters by an electronically controlled fan and led through the
breathing hose into the face piece. The overpressure prevents the ingress of pollutants from the environment into
the head piece.
The usage of a respirator has to be part of a respiratory protection program. You can find more information about the
issue in EN 529:2005.
The instruction manuals enclosed to the mentioned standards refer to important aspects of the respiratory protection
program; however, they do not apply as replacement for national and local regulations (e.g. BGR 190-rules for the use
of respiratory protection devices / BGI 504-26 – selection criteria for special occupational-medical provision according
to the guideline G26 “respirators” of the trade association)
If you are unsure about the selection and handling of the equipment, contact your supervisor or the point of sale. You
can also contact the e-breathe Safety Technical support or selected service centers at any time.
1.1 Warnings
The equipment must not/should not be used:
EN 12941 Blower with Hoods, Head Pieces and Suits
•
when the blower is switched off or goes off during operation. If the blower turns off by accident, the device
ceases to function as a respirator, and carbon dioxide levels may instantly rise. This is considered an exceptio-
nal situation. Exit the hazardous area immediately.
EN 12942 Blower with Full Face Mask and Half Face Mask
•
when the blower is switched off or goes off during operation. If the blower turns off by accident or the power
supply is interrupted, the respirator should not be taken off because it continues to function as an underpres-
sure device. Immediately leave the hazardous area and report the defect.
•
in case of heavy breathing, dizziness, nausea or other types of discomfort.
•
if the smell or taste of contaminants is noticeable.
•
The filtering device must not be used if the environment and contamination is unknown. In case of doubt,
isolating respirators (air supply) which function independently of the atmosphere must be used.
•
in environments that are directly dangerous to life and health (IDLH).
•
The filtering device must not be used in confined spaces (e.g. cisterns, tunnels) because of the risk of oxygen
deficiency or presence of heavy oxygen-displacing gases (e.g. carbon dioxide).
•
The filtering device may be used only if the oxygen content of the air is 18–23 vol.%.
•
in atmospheres with oxygen or oxygen-enriched air.
•
The blower and accessories must not be used in areas where there is a risk of explosion.
•
If you are unsure about the selection and handling of the equipment, please contact your supervisor or the
point of sale.
1.2 Limitations
2.1 Blower Unit
2. System Components
The e-breathe e-Flow PAPR consists of a basic blower unit with integrated motor and electronics, an exchangeable
Li-Ion battery, a carrying system / strap, a charging station, an exchangeable filter adapter for use with round thread
filters or for use with the e-breathe ecoPAD filter media / filter cartridges.
The following characteristics distinguish the e-Flow PAPR system:
• at least 4 hours operating time
• up to 400 times rechargeable lithium-ion battery
• Switch on/off and select menu items using one and the same control button
• three-stage adjustable airflow via one push-button
• Colour display with clear symbols
• automatic airflow control with integrated air pressure and temperature monitoring
• monitoring of the airflow, remaining filter capacity and battery charge level by the intelligent system
• 2 stage warning / alarm system:
- Warning: visual signal through flashing display with illustration of the warning and acoustic signal tone
- Alarm: visual signal through flashing display with illustration of the warning and acoustic signal tone and mechanical
alarm by vibration
The respirator must be used with at least two particle filters, gas filters or combination filters!
•
Only qualified persons, who are absolutely aware of the work-related dangers and are familiar with the use and
operations of the device, may use the product.
•
Respiratory protective devices must be selected according to the type and concentration of the hazardous sub-
stances.
•
Insufficient warning characteristics of hazardous substances require special rules of engagement.
•
Only filters, which are approved by e-breathe, may be used. The use of other filters is not allowed and can lower
the protection class.
•
Carefully check the identification of the filters to be used together with the blower and make sure not to confu-
se the classification according to EN 12941 or EN 12942 with the classification of the blower according to other
classification standards.
•
The blower must always be used with at least two filters of the same type. If several filters are used, replace them
at the same time.
•
Gas filters do not protect against particles. Similarly, particle filters do not provide protection against gases or
vapours. In case of doubt, use combination filters.
•
Particle filters are only allowed for single use if they are applied against radioactive agents or microorganisms
(virus, bacteria, fungi and spores).
•
Gas and combination filters have to be exchanged when recognizing smell or taste.
•
Filters should not be attached directly to the face piece or breathing hose.
•
Normal filtering devices do not protect against certain gases such as CO (carbon monoxide), CO2 (carbon dioxide)
and N2 (nitrogen).
•
When working with open flames or liquid metal droplets, there is a risk of ignition of the activated carbon filter
(gas or combination filter) and the associated occurrence of acutely hazardous concentrations of toxic substances.
•
At a very intense working pace, the pressure in the face piece can change into negative pressure at peak inhala-
tion.
•
Make sure that the breathing hose does not get caught in surrounding objects.
•
The equipment may never be carried or lifted at the breathing hose.
•
Before the application of the blower, a check of the minimum airflow volume should be conducted.
