Application
The WSH AIR III fan unit is a powered air purifying
respirator (PAPR) for protection against dust
and particulates. This system is TH3P-certi-
fied according to the European Standard EN
12941:1998, EN 12941:1998/A1:2003, EN
12941:1998/A2:2008, EU Regulation 425/2016
and TH3P-certified according to the Australian
standard AS/NZS 1716. The WSH AIR III fan unit is
used to assist breathing by the wearer. Inhalation is
simplified and the user can operate for longer with-
out becoming tired when compared to working with
a passive filtering system. The electronic flow control
system monitors the fan and ensures a constant
airflow of at least 170 L/min. The actual operating
time of the WSH AIR III fan unit with a fully charged
battery depends on the battery type and filter condi-
tion (see the "Technical data" table).
First use
Checking before first use
Prior to checking before first use:
▸
Fully charge the battery before first use.
▸
Check whether the device as supplied corre-
sponds to the scope of delivery and that it is free
from damage.
▸
Never use a damaged or incomplete device.
Please check the following components carefully:
▸
Check the battery for damage.
▸
Check the hose for damage.
▸
Check the belt/shoulder strap for damage.
Checking before first use
Prior to every use, ensure that the WSH AIR III
fan unit is in a fault-free condition and proceed as
follows:
1. Ensure that the main and pre-filter are correctly
installed and that the unlocking lever of the cover
is tightly secured (the cover must engage with an
audible click when closing) (fig. 1).
2. Check the air hose and the air connection for
damage (holes, cracks, cuts, etc.). Connect the air
hose to the helmet and the fan by pressing the
hose onto the counter piece until it engages with
an audible click (fig. 2).

3. Switch the WSH AIR III fan unit on by pressing
the on/off button for about 0.5 seconds (fig. 3).
During the three-second switch-on phase, all five
LEDs come on (three green LEDs for the airflow
setting and two red LEDs, of which one indicates
the battery status and the other indicates the filter
condition (fig. 4), and an audible alarm (three
beeps) sounds. Thereafter, the WSH AIR III fan
unit is operational.
4. In addition, the WSH AIR III fan unit carries out a
self-test during the switching-on phase to ensure
that the device has created a sufficient airflow of
over 170 L/min. If the red filter LED goes out af-
ter the 3-second switch-on phase, an airflow of at
least 170 L/min is being maintained. The WSH
AIR III fan unit monitors the airflow continuously
during operation and maintains it above 170 L/
min.
5. As described above, the WSH AIR III fan unit
has a visible and an audible alarm (fig. 5) for
low battery capacity as well as for a missing,
clogged or incorrectly inserted filter. In the event
of an alarm, leave the danger zone immediately!
Ensure that the alarm for low airflow/filter clog-
ging is functioning by simulating a too low airflow
as follows. With the WSH AIR III fan unit switched
on, disconnect the hose from the helmet and press
the palm of your hand onto the hose end. The mo-
tor then accelerates automatically to compensate
for the low airflow. Press the palm more tightly
against the hose end to form a tight seal. Once
the seal is formed, the device outputs an audible
alarm and the red filter LED comes on.
6. To stop the alarm, press the on/off button for
about three seconds and connect the hose to the
safety helmet.
7. Check that the safety helmet is undamaged, put it
on and strap the PAPR around the waist.
8. Start the fan and ensure that the air circulates nor-
mally around the safety helmet.
If damaged, the defective parts must be replaced
before the PAPR can continue to be used.
