Introduction
A blower filter device is a device designed to supply filtered fresh air to a welding
helmet or a grinding helmet (safety helmet) approved in conjunction with this device.
By following these instructions and the instructions of the safety helmet used for this
purpose, the user is protected against dust and particles in the air he/she breathes.
Safety instructions
Please read these operating instructions carefully before using the device.
Unintended use may endanger life and health and void any warranty claims against
Optrel.
Warnings & and safety limitations / risks
Wear the helmet only when it is connected to the blower and the blower is in
operation. The blower may only be used in conjunction with breathing apparatus
that meets the requirements of the European and Australian Standards. This PAPR
does not protect against gaseous substances. Before you start working, put the
device on and switch it on� You can only enter the danger zone safely after doing
so. In the event of a malfunction of the blower, leave the danger zone immediately.
As soon as the battery alarm (red LED and audible signal) is activated, you must
leave the danger area immediately. Charge or replace the battery. As soon as the
air flow alarm is activated (the red LED lights up and an audible signal is output),
immediately leave the danger zone and replace the filter.
If there is a strong wind from the side or from behind, the protective function of
the helmet may be impaired. In environments with a very high level of particle
contamination, negative pressure can develop in the protective helmet when
breathing in. This could impair the protective effect. In this case, do not remove the
helmet or switch off the blower until you have left the danger zone� When taking off
the helmet, take all necessary precautions to avoid inhaling dust or contaminated
material that may have accumulated on the outside of the helmet� Never immerse
the fan or battery in water as this may damage the unit� Prevent water ingress into
the unit during cleaning. Used filters cannot be cleaned or reprocessed. Attempts
to clean the filter with compressed air or water may damage the filter. Do not short-
circuit the battery; this can cause serious damage�
The hose cover should be replaced every 6 months. Due to intensive UV and
IR irradiation, the tube cover loses its flame retardant effect. Before use always
examine the hose cover carefully to determine whether bleached, light or brown
areas have formed in the textile. As soon as light or matt areas are visible, the hose
cover must no longer be used and must be replaced.
The PAPR must not be used:
- in flammable or explosive atmospheres,
- if the oxygen content in the breathing air is too low (Europe: <17%, Australia: <19)
or if the toxin concentration is so high that a higher protection class than TH3P
(Europe and Australia) is required,
- at temperatures below -5 °C or above +55 °C,
– in environments where there is an imminent danger to health and life�
If you have questions about the specific application, use, or suitability of the e3000
system, please contact Optrel Customer Service.
Warranty & liability
Optrel will repair or replace the product as needed if a defect in materials or
workmanship occurs within 24 months of the date of purchase, provided the product
has been used as directed in the instruction manual� The warranty is void if the serial
number has been changed, removed or made illegible, or if the product has been
intentionally damaged, misused, opened or modified. The warranty also expires in
the event of incorrect use, use of non-original spare parts or lack of maintenance.
The warranty only covers the repair or replacement of defective parts. Under no
circumstances shall Optrel be liable for any general failures or consequential
damages�
Expected Lifetime
The e3000 has no expiration date. The product can be used as long as no visible or
invisible damage or malfunctions occur�
Field of application
The e3000 is a blower filter unit (PAPR) for protection against dust and particles.
This system is TH3P certified according to European Standard EN 12941:1998 and
TH3P certified according to Australian Standard AS/NZS 1716:2012. The e3000
is used to support the ventilation process. This reduces the effort of inhaling and
thus the fatigue. The electronic flow control system monitors the blower to ensure a
constant air flow of at least 150 Nl/min*.
The effective operating time of the e3000 with a fully charged battery depends on
the battery type and filter condition (see table "Technical data").
Before you carry out the test before commissioning
Carefully remove the packaging of the individual parts.
●
Check that the unit is complete as supplied and that nothing has been damaged. If
●
there is any damage or parts are missing, contact customer service immediately.
Never use damaged or incomplete equipment.
The battery is not fully charged on delivery. Therefore, fully charge the battery
●
before using it for the first time.
Testing before commissioning
Before each use, make sure that the e3000 is in perfect condition and proceed
as follows:
1. Make sure that the main filter and prefilter are correctly installed and that the
release lever firmly fixes the cover (the cover must snap into place with an
audible click when closed) (Fig� 1)�
2. Check the air hose and the air connection for damage (holes, cracks, cuts).
Connect the air hose to the helmet and blower by pressing the hose on to the
mating part until it snaps into place with an audible click (Fig. 2).
3. Switch on the e3000 by pressing the On/Off button for about 0.5 seconds (Fig.
3). During the 3-second start-up phase, all 5 LEDs light up (3 LEDs for setting
the air flow level in green and 2 LEDs in red, one indicating the battery status
and the other the filter status - Fig. 4) and an audible alarm (3 beeps) is output.
The e3000 is then ready for operation.
4. In addition, the e3000 performs a self-test during the start-up phase to ensure
that the unit is generating a sufficient air flow of above 150 l/min. If the red filter
LED goes out after the 3-second switch-on phase, an air flow of at least 150 l/
min is maintained. Using a built-in flow meter, the e3000 constantly monitors
the air flow throughout operation and maintains it above 150 l/min.
5. As described above, the e3000 has a visible and audible alarm (Fig. 5) for low
battery capacity and missing, clogged or incorrectly inserted filters. In the event
of an alarm, leave the danger zone immediately!
Make sure that the low air flow/filter clogging alarm works by simulating a low
airflow as follows.
While the e3000 is switched on, remove the hose from the helmet and press
the ball of your hand against the end of the hose� The motor then accelerates
automatically to compensate for the low airflow. Continue to press the ball of
your hand firmly against the end of the hose to seal it tightly. When this occurs,
the unit emits an audible alarm and the red filter LED lights up.
6. To stop the alarm, press the On/Off button for about 3 seconds and connect the
hose to the helmet�
7. Make sure the helmet is undamaged, put it on and fasten the PAPR around your
hips.
8� Start the blower and make sure that the air in the helmet is circulating normally�
In the event of damage, you must replace defective parts before using the PAPR.
Operating mode
Adjusting the belt size: Put on the belt (Fig� 6) and adjust the size so that the blower
unit sits comfortably on your hips.
Removing the air hose: Push in the hose connection on both sides and pull it off
the mating part (Fig. 7).
Inserting the rechargeable battery: The battery must be inserted into the
appropriate guide on the right underside of the e3000. Push the battery forward
until it audibly snaps into place (Fig. 8).
Removing and charging the battery: Pull the battery release lever back and
slide the battery along the guide and completely out of the blower unit (Fig. 9). Then
connect the battery to the charger (Fig. 10). The charging process is indicated by
the yellow LED on the charger. When charging is complete, the LED shows green
and trickle charge mode is activated�
Adjusting the air flow: The blower has three air flow levels: 150/200/250 Nl/ min*.
To change the air flow level, press the air flow button and scroll through the different
levels until the desired level is reached (Fig� 11)�
Replacing the main filter and prefilter: If a filter alarm is output, the prefilter must
be replaced (Fig. 12). Please monitor the time between filter alarms. This becomes
shorter each time the prefilter is replaced. If you have the impression that the change
intervals are too short (this is a personal impression), it is recommended to replace
the main filter and the prefilter (Fig. 13).
